This fungicide guide is based on the latest

information available from the North Dakota

Agricultural Experiment Station, U. S. Department

of Agriculture, U.S. Environmental Protection

Agency (EPA) and agricultural chemical industry.

The information conformed to federal and state

regulations at the time of printing. The user should

determine that the intended use is consistent with

label directions. Designation that a product is

labeled for control of a crop disease does not

imply endorsement by the authors of use of that

product or the degree of efficacy of that product

for that use.

Always follow label directions, making certain to

check instructions on how to apply, when to

apply, waiting periods prior to harvest, whether

treated crops can be fed to livestock, and

important safety precautions.

LABEL PRECAUTIONS, RESTRICTIONS

Field re-entry, handling and loadingprecautions

Most fungicide labels state that workers either shouldnot enter a sprayed field until the sprays have dried orshould not enter for 24 hours unless they wearappropriate protective clothing. Information on use ofprotective clothing during mixing and loading also is givenon the label. See the label for details.

Replant restrictionsLabels for all formulations of Ridomil have restrictions

on what crops can be planted in less than a year followingapplication of the product. These restrictions may varysomewhat depending on the formulation. Check the labelbefore application to determine if replant restrictions willcause problems when determining what crop to plant nextseason.

DosagesAll dosages given in this guide are stated as the

amount of formulated product (lb., oz., fl. oz., quarts) touse.

Restricted use fungicidesFungicides containing triphenyltin hydroxide are

restricted-use fungicides. These include Super Tin, AgriTin and Super Tin 4L. These are designated as RUP andRestricted-use Pesticide in the tables.

DisclaimerThe information given herein is for educational

purposes only. North Dakota State University does notendorse commercial products or companies, even thoughreference may be made to trade names, trademarks orservice names. Omission of labeled products ispossible if information about the product was notavailable at the time of printing or if it hadquestionable efficacy. Products not normallyavailable in North Dakota are omitted from the guide. Seed treatment chemicals that are primarilyinsecticides with subminimal amounts of fungicideare also omitted.

The plant pathology faculty at North Dakota StateUniversity assumes no responsibility for property damage,personal injury or other loss due to the use of fungicideslisted in this publication, as they have no control over theuse or misuse of these products.

FUNGICIDE FORMULATIONS

Most fungicides are solids that are not soluble inwater. To use them, they must be made into a formulation(preparation). Some of the more common formulations arelisted below. The common abbreviation for eachformulation is given in parentheses following the name.

Wettable powders (WP)Many fungicide are wettable powders consisting of

solid fungicide and a wetting agent. When mixed withwater, they form a suspension. Many of these suspensionssettle out quickly, so an agitator is needed in the spray tankto keep the particles in suspension.

Water Soluble Pouch (WSP)Some fungicides are available in water-soluble pouch

containers. These pouches dissolve in the mixing tank andrelease the fungicide. This reduces the exposure of mixerand loader personnel to dust from the fungicide.

Dusts (D)Dusts are powders that are mixed with inert

ingredients to form a product with a low percent of activematerial. These are used around the home garden, and afew formulations are used in commercial applications.

Granules (G)The active ingredient is incorporated into small

granules of inert material such as clay. Granules areincorporated into the soil.

Emulsifiable concentrates (EC)A fungicide that is insoluble in water is dissolved in an

organic solvent. An emulsifying agent is incorporated inthe formulation, so an emulsion is formed when the productis mixed with water. An emulsion is a suspension of verytiny drops of the solvent/fungicide in the water. It usuallyhas a milky appearance (milk itself is an emulsion of fats inwater).

Flowables (F)Flowables are insoluble fungicides ground into a very

fine product, usually by a wet grinding process. Theseparticles are nearly colloidal in size and are suspended inwater to form a thick liquid. They remain suspended inwater for relatively long periods of time, but should beagitated before use. They are dust-free, easy to mix,remain in suspension longer than wettable powders, andalso may resist washing off the plant better than thewettable powders. Examples of flowables include ChampFlowable, Kocide 4.5 LF, Vitavax 200, and Dithane F-45. They need to be protected from freezing.

Dry flowable (DF)See dispersible granules.

3

Dispersible granules (DG)Dispersible granules also are called dry flowable

formulations. They are small-sized granules that pourfrom a container like a liquid, but do not stick to the sidesof the container and do not need to be protected fromfreezing. They are virtually dust-free and disperse readilyin water to form a suspension. Examples include BravoUltrex DG, Dithane DF, Rainshield NT, Manzate 75 DF,and Penncozeb DF.

FumigantsFumigants are liquids that turn into a gas after

application. They generally are used for soil fumigation.

MODE OF ACTION OF FUNGICIDES

The action of most fungicides takes place outside thehost and is called "protection.” A fungicide that actsoutside the host is called a "protectant fungicide.” Mostolder fungicides sprayed on leaves and fruit are of thistype. "Therapy" is chemical action inside the host. Triadimefon (Bayleton) has several days of therapeuticaction against wheat leaf rust and also reduces theproduction of viable spores; that is, spores capable ofgrowing. Propiconazole (Tilt) has several days oftherapeutic action against wheat leaf rust, tan spot andseveral other diseases and reduces the production ofviable spores.

Most protectant fungicides are relatively stable bythemselves. Generally they are relatively insoluble inwater and resist removal or chemical change by water, yetmust be toxic to fungi. Often a chemical change isbrought about by the fungus, the host, or the environmentbefore toxicity occurs. Toxicity simply means the ability todamage the fungus cells.

Fungicides may act to produce a toxic reaction in thefungus in several different ways. (l) Some may inhibit(slow down or stop) cell wall formation. Propiconazoleand triadimefon act this way on cereal rusts. (2) Thepermeability of the cell wall may be affected, causing aleaking of nutrient materials from the cell. (3) Somefungicides may combine with essential metals in a waythat they become unavailable for normal cell functions,including the functioning of essential enzymes. (4) Otherfungicides may inhibit respiration, or nuclear division, ormay break dormancy of spores.

Some fungicides also may be toxic to plants if appliedat rates too high, or if applied under unfavorableenvironmental conditions. This is called phytotoxicity.Formulations of maneb + zinc are less phytotoxic to manyvegetables than formulations that contain only maneb. Sometimes the method of formulation may make afungicide less phytotoxic.

TOXICITY OF FUNGICIDES

Toxicity ratings of pesticidesPesticides generally are categorized according to

acute oral toxicity (the toxicity when taken by mouth), butbecause users may absorb a significant quantity of thepesticide through their skin, dermal toxicity (toxicity whenabsorbed through the skin) is of equal or greater practicalimportance.

LD50 values generally show relative toxicities amongthe chemicals and are not truly representative of effects onhumans, especially since they usually are obtained on rats. Actual toxicities do not constitute the only hazardsassociated with exposure to the chemicals. For instance, achemical with low toxicity may be hazardous due toconcentration, high volatility, careless use, or effects oflong-term exposure.

LD50 depends upon body weight. Thus, a givenamount of chemical would have greater effect on a childthan on an adult. LD50 also is proportional to the percent ofactive ingredient. A material only 50 percent activerequires twice as much to produce a toxic effect as l00percent pure material.

The lower the LD50 value, the greater the toxicity. Acommon standard for comparison is aspirin, which has anLD50 of l,200 mg/kg and is considered slightly toxic.

The following table illustrates the various toxicity classes:Oral Toxicity Dermal (Skin) Toxicity

LD50-mg/kg Toxicity Class LD50-mg/kg Toxicity Class

1-50 High 1-200 Severe

50-500 Moderate 200-2,000 Moderate

500-5,000 Low 2,000-20,000 Mild

Over 5,000 Very Low Over 20,000 Very Mild

Low and very low orders of toxicity generally are considered to be of low hazard. Most fungicides are inthese toxicity classes. The toxicity of various fungicides isshown on the following table.

Handling chemicalsAvoid splashing and spilling. Wear a mask especially

when handling dusts or powders. Some chemicals, whencombined, have increased toxicity (potentiation).

Rinse containers several times after using chemicals. Pour rinsate into spray tank when using the samechemical. Dispose of containers as indicated in nextsection. Keep a record of plant disease control chemicalsused and methods of handling.

Fungicide Labels

Fungicides are named according to their chemicalcomposition or the chemical name. An example of achemical name is a coordination production of zinc ionand manganese ethylene bisdithiocarbamate; thechemical names are required on the label. Sincechemical names are frequently long, common names frequently are used; for example, the common name forthe above chemical is mancozeb. Manufacturers usetrade names to identify their specific products. Forexample, there are various trade names for mancozebsuch as Dithane, Manzate, and Penncozeb.

In addition to the names on labels, various other requiredlabel information includes: precautions in handling,antidotes or telephone contacts to use in case ofaccidental poisoning, recommendations for use, materialscontained in the package and their percentages, the

manufacturer's or distributor's name and address, and theEPA registration number.

Some fungicides are made up in various formulationsfor different uses or methods of application such as: wettable powders, dusts, emulsifiable concentrates,granules, flowables, dispersible granules, or solutions. The nature of the chemical sometimes restricts it to one ora few of these formulations.

Note: Although maneb and mancozeb are very similarproducts, there are some differences in registration. Besure to consult and follow label directions.

Protecting Groundwater

Pesticides differ in their persistence and mobility insoil. Those which are highly persistent or highly mobileare more liable to contaminate groundwater than thosethat are not. Areas of the state where groundwater ismost at risk are areas with coarse-textured soils, are lowin organic matter and have a high water table. Mostfungicides are relatively immobile, especially in clay soilswith high organic matter because they are adsorbed onclay particles or on the organic matter.

A few fungicides are somewhat mobile. Take care inthe use of these fungicides, particularly the application ofthese products through a sprinkler irrigation system inhigh-risk areas. Risks may be reduced by minimizing theamount of water used for application through a sprinklersystem, more use of ground or aerial application insteadof application through the sprinkler system, and use of adifferent fungicide that is less mobile.

The persistence and mobility of fungicides commonlyused in North Dakota are shown in the accompanyingtable. For more information, consult NDSU ExtensionService publication EB-49 “Persistence and Mobility ofPesticides in Soil and Water.”

Seed Treatment

Cereals Fungicidal seed treatment helps protect the seed

from rotting and the emerging seedlings from damping offand seedling blight. These are caused by soil-bornepathogens. When seeds germinate under favorable soilconditions, there is less danger of seed and seedlingattack from soil-borne pathogens unless seed is of poorquality. Treatment of seed with a protectant fungicidemay help protect against soil-borne pathogens and thushelp stand establishment when seeds are germinatingunder unfavorable conditions, such as cold wet weather.Many products are available for protection againstseedling blight.

Treating seeds with a fungicide also helps protectthem from diseases that are seed-borne. These includethe covered smuts, bunt, scab, black point, and blacksemi-loose smut of barley, and loose smuts of wheat,barley and oats. Loose smuts of wheat and barley areinternally seed-borne. Loose smut of oats is seed-borneas spores under the hulls. These smuts cannot becontrolled by conventional protectant seed treatmentfungicides, but are controlled by systemic seed treatmentproducts. The embryo test can be used by the NorthDakota State Seed Department to determine if loose smutis present in barley seed. This test cannot be used for the

loose smuts of oats or wheat or black semi-loose smut ofbarley. All current barley varieties are susceptible toloose smut. An embryo test is recommended for barleyseed; if infection is 2percent or greater, seed treatment ofbarley with carboxin or triadimenol is advised.

Common (Bipolaris, Helminthosporium orCochliobolus) root rot of wheat and barley is a chronicproblem in North Dakota, causing average yield losses of5 to 11 percent, with much greater losses in some fields incertain years. Several seed treatment products arelabeled for suppression of common root rot.

ChickpeasTreating chickpea seed to protect against Pythium is

essential for good emergence. A seed treatment to protectagainst seed-borne Ascochyta is important as this is acommon and serious disease.

Dry beans and soybeansTreating seed may reduce seedling blight during

weather that is unfavorable for emergence. Do not usestreptomycin with Rhizobium inoculant. If using captanseed treatments, in-furrow inoculant is preferable,because inoculant does not survive well on captan-treatedseed. Several products can be used to reduce the root rotpotential.

FlaxTreating flax seed with a fungicide helps protect

against seed rot, damping off, and seedling blight. Seedtreatment is especially important in cases where the seedcoats are broken, allowing entry of pathogens. Seed fromfields heavily infected with Pasmo (Septoria linicola) maybe susceptible to seedling blight and should be seedtreated.

Potatoes Treatment of cut seed-pieces helps protect the cut

surface against seed-piece decay. Most seed treatmentsare fungicides that will protect against fungi such asPythium, Rhizoctonia and Fusarium. Fungicides do notprotect against bacteria such as Erwinia or Clavibacter. However, control of fungi indirectly helps control Erwiniabacteria because seed decay is greater in seed infectedwith fungi. The addition of streptomycin to fungicide haslimited value because it will control only bacteriacontaminating cut surfaces and may inhibit woundhealing. Seed treatment will reduce or help control newinfections but will not cure existing decay, prevent lenticelinfection or prevent infection of roots and stolons awayfrom the seed piece due to soil or environmentalinoculum. Seed treatment is no substitute for using goodsound healthy seed. Seed should be stored at 40F duringthe winter. In the spring, warm the seed to 60-70F for 11/2-2 weeks before planting. Do not handle the seed untilit is warm. Plant the cut seed in warm (50-58F at plantingdepth) moist soil. If cut seed must be held, store in a well-ventilated area for suberization at 60-70F with a relativehumidity of 85 percent. Hold for 1 week, then lower thetemperature to 50-60F.

8

SafflowerSafflower rust is both seed-borne and soil-borne. The

most devastating phase of the disease is a seedlingblight, and root and foot rot. Typical rust pustules developlater on the leaves. Seed-borne safflower rust iscontrolled by seed treatment.

SunflowerSoil-borne downy mildew infections were controlled

with metalaxyl or mefenoxam seed treatment in the past.The downy mildew fungus, however, has developedinsensitivity to metalaxyl and mefenoxam in much of NorthDakota, South Dakota, and Minnesota, so thesefungicides are not always effective. Several fungicides orfungicide-insecticide combinations have received state orfederal labels for seed treatment of sunflower for seed rotand seedling blights.

Application of Seed Treatment

Seed may be treated commercially or it may betreated on the farm. Commercial seed treatment may usea slurry treater or various automatic seed treaters. Thevarious automatic seed treaters differ considerably and socannot be discussed here. Commercial operators usingflowable fungicides should be sure to clean off thechemical metering cups every day to prevent a buildup offungicide which reduces delivery rates.

On-farm treatment may use various home-type orslurry mixers. Drill-box seed treatment is popular becauseno extra steps are required because the seed is treated inthe drill-box at planting time. Use caution when usingdrill-box seed treatment. Good disease control dependson uniform fungicide coverage of the seed. This is moredifficult to accomplish in drill-box treatment becausethere’s an inadequate means of mixing the seed andfungicide. For effective drill-box treatment, fill the box withone-third the quantity of seed and fungicide and mixcarefully with a paddle; repeat with the next third, and thenthe final third. The paddle should not be used for anyother purpose and should be stored in a safe place, out ofreach of children and animals.

The most common and satisfactory on-farm seedtreatment method is to meter fungicide into the base ofthe auger used to fill the drill box. This assures fairly goodmixing and coverage. If a powder is used, dust may be anirritating problem; adequate protective clothing and achemical respirator should be used. If a liquid is used,there is no dust problem.

All seed treatments have certain basic precautions.Use care in handling seed treatment products – if nothighly poisonous, many are at least irritating to the eyesand nose. Treated seed usually is identified by the dyeused in the chemical, and treated seed should not be fedto livestock or used for human food. Pesticide containersshould be disposed of properly in a landfill or buried in anarea where there is no surface drainage to nearby waterways. If seed treatment cannot be done outdoors, itshould be done in a well-ventilated room. Commercialseed treaters should have an adequate air exhaust

system for treatment rooms. Workers exposed to seedtreatment chemicals for long periods of time should havean approved chemical mask. The filter should bechanged frequently. Recommended rates of applicationshould be followed carefully as higher rates may injure theseed and lower rates may not give satisfactory diseasecontrol.

Forage legume seed should be treated well inadvance of planting and inoculated with nitrogen fixingRhizobia at planting time. If dry beans have been treatedwith streptomycin for control of externally borne blightbacteria, inoculating with Rhizobia is not available.

Field Crops Foliar SpraysFoliar fungicides are used to control fungal disease

organisms that attack the above-ground portions of plants. Fungicides are used to protect the potential yield andquality of a crop. The majority of these fungicides protectfoliage from infection; therefore, these fungicides must beon the foliage before the fungus spores germinate.

Several foliar fungicides act differently from theprotectants described above. The benzimidazolefungicides thiabendazole and thiophanate methyl areabsorbed by the plant and translocated up the plant by theconducting tissues. They are called systemic fungicides. They only move up the plant; they do not move down. Thus, to control white mold on dry beans, completecoverage of stems, lower leaves and blossoms isrequired. Spraying only the upper leaves is notsatisfactory because the fungicide will not move down tothe location where it is needed. Azoxystrobin, and propiconazole and other triazoles, are locally systemic,they have some upward mobility and translaminarmovement and have some limited therapeutic action. Metalaxyl will move down from potato foliage into tubers inlimited amounts to provide tuber protection againstmetalaxyl- sensitive strains of the late blight fungus andpink rot infection.

Spray control programs to prevent disease have beendeveloped from data through years of research. Becauseeach disease develops in a distinct manner, the decisionto use a disease prevention program is based on weatherconditions, disease development, potential yield of thecrop, and the dollars returned to management with use ofthe fungicides.

Many fungicides are registered for application througha sprinkler irrigation system, as well as by a spray. If afungicide can be applied through a sprinkler system(fungigation), this is noted under application.

Whenever possible, avoid the continuous use of asingle (or related) fungicide. This is especially importantwith the benzimidazole fungicides and metalaxyl (seebelow, Resistance to Fungicides).

Most fungicide labels contain information on field re-entry, handling and loading precautions. Most labels statethat workers either should not enter a sprayed field untilthe sprays have dried or should not enter for 24 hoursunless they wear appropriate protective clothing.

9

Information on the use of protective clothing during mixingand loading also is given on the label. See the label for details.

SprayingSpraying can be done with many different types of

ground and air equipment. Getting good coverage isimportant: use at least 5 gal/A should be used for aerialapplication and higher gallonages are required for groundequipment.

Droplet size for aerial application should be 200-400microns (l/64 to 1/128 inch) in diameter. Generally, ifnozzles are pointed back, appropriate nozzles are used,and pressures do not exceed 30 or 35 psi, the correctdroplet size will result. Application should be made withthe boom 6 to 8 feet above the crop.

Some plant surfaces have a waxy or hairy coating onthem, making good coverage difficult. The spray willcollect in large erect droplets which then run off. Wheatand cabbage leaves are good examples. Frequently,using a wetting agent with wettable powders is necessary.Usually this is a spreader-sticker. Certain fungicides maywork better with certain spreader-stickers than others. This type of information usually can be found on the labelor in supplemental brochures. Spreader-stickers usuallyare incorporated in flowable formulations, so adding aspreader-sticker to the spray tank is not necessary.

Resistance to fungicidesFungi may develop tolerance or resistance to certain

fungicides. The sugarbeet leafspot fungus (Cercospora)has developed resistance to the systemic benzimidazolefungicides (benomyl, thiabendazole, and thiophanatemethyl) in the Red River Valley and southern Minnesota. These fungicides should be not used at all in the southernRed River Valley and no more than once a season in atank mix with an unrelated fungicide in the northern RedRiver Valley.

Resistance to the benzimidazole fungicidesthiabendazole (TBZ or Mertect) and thiophanate methyl(Topsin M) has recently developed in the potato Fusariumdry rot pathogen, Fusarium sambucinum, and the potatosilver scurf pathogen, Helminthosporium solani. Thisresistance is common throughout the United States andCanada.

Resistance to iprodione has been reported from otherparts of the country. Cross-resistance to the chemicallyrelated product vinclozolin is common when resistance toiprodione develops. The potato late blight fungusdeveloped resistance to metalaxyl in Europe. The A2mating type of the late blight fungus, which is common inNorth Dakota and Minnesota, is resistant to metalaxyl andmefenoxam.

Reduced sensitivity to strobilurin fungicides have been observed in populations of the early-blight fungusAlternaria sp. on potato in ND.

Tolerance of the sugarbeet leafspot fungus totriphenyltin hydroxide was widespread in southern

Minnesota and the southern Red River Valley in 1999,and common in the northern Red River Valley. Tin-tolerantstrains have not survived well when an alternativefungicide was used.

In contrast, benzimidazole-resistant strains survivevery well when alternative fungicides are used, and persistfor a long time. The best way to combat resistance is toprevent or delay it by alternating the use of differentclasses of fungicides and by avoiding constant use offungicides known to trigger development of resistantfungi. Using tank mixes of unrelated fungicides also isreported to retard the development of resistance.

Fungicide Resistance Management Statem ents The following statements are recommendations fromthe Fungicide Resistance Action Committee (FRAC),whose website is: http://www.frac.info/

1. Methyl benzimidazole carbamates (MBC; Group 1)– High risk. Both mixtures and alternations with non-Group 1 fungicides are acceptable methods ofpreventing/managing resistance to Group 1 fungicides. For high risk pathogens, mixtures are preferred toalternations.

2. Dicarboximides (Group 2) – Medium to high risk. Minimize the selection pressure by minimizing the numberof applications. As a guide, do not apply more than two tothree per crop per season. Maintain regular prolongedtimes without exposure to Group 2 fungicides. Whenapplying for Botrytis control: Restrict applications to thosetimes when Botrytis infection pressure is high. WhereBotrytis resistance is well established, use combinationsto stabilize Botrytis control, but their application mustfollow the same rules as for Group 2 fungicides alone.

3. Sterol biosynthesis inhibitors (SBI; Groups 3, 5,17, and 18) – Low to medium risk. Repeatedapplications of SBI fungicides alone should not be usedon the same crop in one season against a high-riskpathogen in areas of high disease pressure for thatparticular pathogen. For crop/pathogen situations whererepeated spray applications are made during the season,alternation or mixtures with an effective non cross-resistant fungicide are recommended. Where alternationor the use of mixtures is not feasible because of lack ofeffective or compatible non cross-resistant partnerfungicides, then input of SBIs should be reserved forcritical parts of the season or crop growth stage. If SBIperformance should decline and sensitivity testing hasconfirmed the presence of less sensitive forms, SBIsshould only be used in mixture or alternation with effectivenon cross-resistant partner fungicides. The introduction ofthe new classes of chemistry offers new opportunities formore effective resistance management. The use ofdifferent mode of actions should be maximized for themost effective resistance management strategies. Usersmust adhere to the manufacturers’ recommendations. Inmany cases, reports of “resistance” have, oninvestigation, been attributed to cutting recommendedrates of use, or to poor or miss-timed application.

10

Fungicide input is only one aspect of crop management. Fungicide use does not replace the need for resistant cropvarieties, good agronomic practice, planthygiene/sanitation, etc.

4. Phenylamides (PA; Group 4) – High risk. TheGroup 4 fungicides should be used on a preventative andnot curative or eradicative basis. For foliar applications,Group 4 fungicides should be used in pre-packedmixtures with an unrelated effective partner and used in asound management program. Where using residualpartners, use between three-fourths and fullrecommended rates. The Group 4 fungicide dosage inthe mixture depends on its intrinsic activity and is definedby the respective company. The Group 4 fungicidesshould not be used as soil treatments against airbornediseases. When solo formulations are made available forsoil use, strategies that prevent any possibilities for foliarapplications must be implemented. For seed treatment,mixtures rather than straight Group 4 fungicides should beused whenever possible. The number of Group 4fungicide applications should be limited (two to fourconsecutive applications per crop and year). Theapplication intervals should not exceed 14 days and maybe shorter in cases of high disease pressure. If rates andapplication intervals are reduced, the total amount of theGroup 4 fungicide used per season should not exceedthat of the full rate, and the total exposure time shouldremain the same. The rate of the mixing partners shouldremain the same for both intervals. Group 4 fungicidesprays are recommended early season during the periodof active vegetative growth of the crop. The growershould switch to non-Group 4 products not later than thenormal standard application interval of the non-Group 4product.

5. Quinone outside inhibitors (QoI; Group 11) – Highrisk. When using a Group 11 fungicide as a solo product,the number of applications should be no more than one-third of the total number of fungicide applications perseason. In programs with tank mixes or pre-mixes of aGroup 11 fungicide, applications should be no more thanone-half of the total number of fungicide applications perseason. In programs in which applications of Group 11fungicides are made with both solo products and mixtures,the number of Group 11 fungicide-containing applicationsshould be no more than 1/2 of the total number offungicide applications per season.

Fungicide Groups

The Soil Application and foliar sprays tables in this guidehave a numerical or letter designation (in parentheses) foreach chemical component of the listed commercialfungicides. This number or letter code indicates thefungicide group to which the chemical belongs. Thefungicide groups have been designated by the FungicideResistance Action Committee (FRAC). FRAC is aSpecialist Technical Group of the Global Crop ProtectionFederation. The members of this committee arerepresentatives from all major crop protection companiesworldwide. The FRAC code of numbers and letters arewidely accepted in the literature.

The purpose of FRAC is to prolong the effectiveness offungicides liable to encounter resistance problems and tolimit crop losses should resistance appear. If fieldresistance is known to one member of the FungicideGroup, it is possible that cross resistance to otherchemicals within that Group will be present. ThisFungicide Guide is providing information on FungicideGroups so that users are aware of potential resistanceproblems with continued use of chemicals in the sameFungicide Group. The intrinsic risk for resistance todevelop to a given fungicide group varies amongchemistries; for example, resistance development amongthe strobilurins, Group 11, is much more likely thanresistance development among the mancozebs ormanebs, Group Y. For more information about FungicideResistance and the FRAC Fungicide list, see the followingwebsite: http://www.frac.info/frac_body.html.

1Spray = ground or aerial, Fungigation = application through sprinkler irrigation system.2Dosage = Amount of formulated product to apply.3X = Product labeled for crop and disease; Blank = product not labeled for specific disease.4Begin when disease is first observed in field. Higher rates are used when disease is severe on susceptible varieties. Use 5-10 gal. water airplane or 20-40 gal water and at least 100 psi with ground equipment. Repeat tin or copper at 10-14 days. Repeat maneb or mancozeb at 7- 10 days.5Because benzimidazole (Topsin M) resistant strains of Cercospora beticola have developed in many sugarbeet growing areas, Topsin M should only be used once per season and only in combination with a non-benzimidazole fingicide. 6Tolerance in the Cercospora fungus to TPTH is widespread in southern Minnesota and in the southern Red River Valley, and common in the northern Red River Valley. In areas where tolerance has been identified or is suspected based on poor performance of TPTH see currentSugarbeet Production Guide for management strategies.7See fungicide resistance management statements of page 9.*Designates restricted use pesticide.
