Rains + Heat = F ly Control Problems

Pasture flies (horn flies and face flies) and confinement flies (stable flies and house flies) need moist breeding materials. Horn flies and face flies develop in fresh cow manure; stable flies and house flies develop in mixtures of manure, decaying hay, and spoiled feed. Quick drying breeding sites can mean that that fewer fly eggs hatch, more maggots dehydrate, and fewer flies make up the next generation. The impact of this environmental control can breakdown if frequent rains keep valuable fly resources productive longer. High temperatures speed up the development of these pests, chopping several days off the development time from egg to adult. This can lead to an extra generation or two during the fly season and higher fly numbers to stress animals and potentially increase transmission of fly-borne diseases. The weather can be too hot and too dry for flies but above-normal rain can give flies the humidity that they need to cope with the heat. The combination of the two can strain usually effective fly control programs.

Pasture Flies Monitor pasture fly numbers on 10% of the herd weekly and record numbers. Good goals are to keep face fly numbers below 10 per head and horn flies below

100 per side. You can catch jumps in fly numbers more quickly with this information and then take steps to increase control. Addition of an oiler or forced-use dust bag can be an effective way to supplement pasture fly control.

Stable Flies Stable flies can be costly pests around dairy and confined beef cattle. These biting flies feed on lower legs and underbellies of animals. Count the numbers of stable flies on the legs of 10% of the herd. An average of 5 or fewer of these flies per leg is a good target. House Flies High populations of house flies are a nuisance that can lead to complaints from neighbors. More importantly, they can carry some diseases associated with animal and human health. Index cards (3 X 5 inches) make good fly monitoring tools. Cards can be pinned to surfaces where flies rest at night (rafters, joists, hanging lights). Resting flies will leave specks consisting of fecal spots and will regurgitate on these cards. Record the speck counts by card location and watch for increases that indicate a growing population. Count specks on the whole card or use square inch sub-sections as appropriate. Fewer than 100 specks per location per week should indicate an acceptable number of flies. Replace the cards at weekly intervals. Space sprays of fast acting insecticides, such as pyrethrins, can be used to knock back fly numbers. Increasing numbers frequently mean improvements in sanitation and water management are needed. Source: Lee Townsend, Extension Entomologist

Be Aware of Poison Hemlock Poison hemlock is toxic to a wide variety of animals including man, birds, wildlife, cattle, sheep, goats, pigs and horses. People are usually poisoned when they mistakenly eat hemlock for plants such as parsley, wild carrot or wild anise. The first notable example of human poisoning was the death of Socrates in 399 B.C. when he ingested a tea made from poison hemlock containing the toxic piperidine alkaloids coniine and gamma coniceine. Cattle seldom eat hemlock but they will if no other forage is available or it is incorporated in hay or silage. A question commonly asked is how much do cattle need to eat to kill them. Unfortunately, the answer is not clear cut. There is considerable variation in the toxic alkaloid content of the plant depending on stage of growth, season, moisture, temperature, time of day, and geographical region (southern plants are more toxic than northern plants). The conium alkaloids have two major effects: 1) rapid, sometimes fatal effects on the nervous system and 2) they are teratogenic agents (causing birth defects in calves and pigs). Cattle have died by eating as little as 0.2-0.5% of their body weight in green hemlock. Poison hemlock is teratogenic if it is eaten by a cow in the first trimester of pregnancy.

Nat ive Prair ies : Insta l lat ion and Management Native Grass and Pollinator prairies provide an environmental component that was traditionally found in much of Kentucky. The planting of these areas can vastly improve the habitat quality for many game species, songbirds, and beneficial insects. Join Extension and Conservation District professionals in a walk around the Boone County Environmental and Nature Center to learn about plant selection, installation, and management techniques for a successful planting of native prairies.

During the past months the evidence of poison hemlock (Conium maculatum) is widespread. Although this plant is often seen along roadways, abandoned lots, fencerows, and other non-cropland sites, in more recent years, it has expanded out into grazed pasture lands and hay fields. Poison hemlock is classified as a biennial that reproduces only by seed. It is capable, however, of completing its lifecycle as a winter annual in Kentucky if it germinates during the fall months. Flowers and new seed are typically produced in late May and June. Plants emerge as a cluster of leaves that form a rosette. Poison hemlock is most noticeable at this stage of growth in late fall through early spring with its parsley-like leaves which are highly dissected or fern-like (Figure 1). The individual leaves are shiny green and triangular in appearance.

As the plant begins to send up flower stalks, the leaves are alternately arranged on the main stem. Each individual leaf is pinnately compound with several pairs of leaflets that appear along opposite sides of the main petiole. As the plant matures, poison hemlock can grow upwards to about 6 to 8 feet tall (Figure 2). At maturity the plant is erect, often with multi-branched stems, and forming a deep taproot. Poison hemlock has hollow stems which are smooth with purple spots randomly seen along the lower stem that help distinguish it from other plants similar in appearance. The flowers, when mature, are white and form a series of compound umbels (an umbrella-shaped cluster of small flowers) at the end of each terminal

stalk. Although poison hemlock is often associated with areas that have moist soil conditions, it can also survive in dry sites. All classes of livestock are known to be affected by poison hemlock. Cattle, horses, and goats are considered to be the most susceptible domestic animals although other animals can be affected as well. Symptoms of poisoning can occur rapidly anywhere within 30 minutes to 2 hours depending on the animal, quantity consumed, and other ecologic factors. Toxicity varies depending on stage of plant growth, location and environment. Poison hemlock foliage has an unpleasant mouse urine-like odor, detectable when near the plant or when a stem or leaf is crushed. Livestock generally avoid it unless forage is scarce but it may be accidently consumed as a contaminant of hay or silage. Poison hemlock contains 8 piperidine alkaloids; the two major ones are coniine (major alkaloid in the seed) and gamma-coniceine (predominate in green, vegetative growth). These alkaloids cause paralysis of the muscles by acting as a neuromuscular blocking agent. Signs of acute poisoning include:

1. Nervousness, trembling, muscle weakness, incoordination 2. Salivation (slobbering) 3. Initial stimulation or excitement followed by depression 4. Dilation of the pupils 5. Weak heartbeat 6. Musty, mousy odor to breath and in the urine 7. Prolapse of the third eyelid across the cornea may cause temporary blindness 8. Death by respiratory failure due to paralysis of respiratory muscles

Although acute disease is a primary concern, an equally serious problem is subacute intoxication of pregnant livestock that causes deformed bones and joints in calves and pigs. The plants must be eaten for an extended period of time during the first trimester of pregnancy. The susceptible stage of gestation for maternal exposure for cattle is from 50-75 days for skeletal defects to occur. These alkaloids continuously reduce fetal movement during tissue formation, resulting in crooked legs, deformed necks and spines. Less commonly, cleft palate results from lack of fetal movement in the head and neck regions

at 30-50 days gestation, resulting in the tongue preventing normal palate closure during embryo development. Fortunately most animals tend to avoid grazing poison hemlock if other forage is readily available. However, animals may be more prone to consume green plants during the late winter and early spring when other forage species are limited. All parts of the plant, including the seeds, are considered to contain the toxic principles coniine and gamma coniceine. Gamma coniceine is considerably more toxic than coniine and is at its highest concentration in early growth. Ingestion of fresh, green plant material may quickly produce signs of intoxication within an hour and last for several hours. As the plant matures, gamma coniceine is reduced (chemically changed) to the less toxic alkaloid coniine. Seeds and dried plant material contain the highest concentrations of coniine. Toxicity may be somewhat reduced in dried plants due to volatility of the alkaloids, but the potential for toxicity still exists, particularly when a sufficient quantity is consumed in dried hay. Seeds are highly toxic and can be a source of poisoning when they contaminate cereal grains fed to livestock. Therefore, extreme caution should be considered before feeding animals hay or grain known to contain poison hemlock. Diagnosis is based on history of plant ingestion, clinical signs and chemical analysis for presence of alkaloids in rumen contents. No specific treatment for poisoning exists. If acute poisoning does not progress to respiratory failure and death, the prognosis for full recovery is good. Avoid overexcitement and stress that may exacerbate clinical signs and result in death. Public health is a concern when dealing with poisoned animals because of the possibility of alkaloid residues in meat. Elimination of plant toxicants through the milk is a minor route of excretion but may be important when consumed by a calf or a human. The principle strategy for poison hemlock control is to prevent seed production which can be a challenge since a fully mature plant is capable of producing 35,000 – 40,000 new seeds. It is too late to utilize herbicide control methods after plants have produced flowers. Therefore, mechanical control efforts (if feasible) such as mowing or cutting down individual plants should be initiated just before peak flower production to avoid or reduce the amount of new seed being produced. Make note of areas heavily infested with poison hemlock (Figure 3) and begin to look for emergence of new plants in the fall. During the late fall (November) or early spring (March) is the best time of year for herbicide treatment. In grass pastures and hayfields herbicide products containing 2,4-D can be effective when applied to young, actively growing plants that are in the rosette stage of growth. Spot treatments with products containing 2,4-D, triclopyr, or glyphosate can also be used depending on the location. Source: Michelle Arnold, Ruminant Extension Veterinarian, J. D.

The Cost of Keeping One Open Cow Can Pay to Have the Herd

Pregnancy Checked Recently the topic of pregnancy checking was discussed. There are several producers who use palpation, ultrasound, or blood test to determine the pregnancy status of cows in the herd. However, there are more producers who use either the eye test or fail to pregnancy check at all. Regardless of what one may think, every producer is faced with the cost of pregnancy diagnosis. On average, pregnancy diagnosis immediately following the breeding season using palpation, ultrasound, or blood test will cost $5 to $10 per head. Alternatively, unless actively looking for signs of a cow returning to estrous, the cost of pregnancy diagnosis is the cost of feeding the cow from the end of the breeding season until the end of the calving

season and then finding out the cow was not bred. That cost can vary depending on the time of year and weather conditions but will generally range from $200 to $400 per head. Thus, finding one open cow in a herd of 40 will essentially pay for pregnancy checking.

2018 Farm Bi l l ADVANCES After a period of uncertainty, the 2018 Farm Bill is back on track with both chambers passing their versions of the nation’s comprehensive farm/food policy legislation. On mainly a partisan vote, the House narrowly passed their version of the bill 213-211 on June 20th, following the defeat of a similar bill in May. The Senate overwhelmingly voted in favor of their farm bill 86-11 on June 28th. Now negotiations between an appointed conference committee will settle the differences among the House and Senate versions as legislators attempt to get a 2018 farm bill signed into law prior to the September 30, 2018 expiration of the 2014 farm bill. If this materializes, it would represent the first time a farm bill has passed on time in more than 20 years. In the midst of a depressed farm economy and trade tensions, leaders in both chambers have expressed their desires that conferees meet immediately after the July 4th recess to merge the two bills and send it to White House for President Trump’s signature prior to the August recess. Structurally, both bills are very similar to the 2014 farm bill, which introduced the Agricultural Risk Coverage (ARC) and Price Loss Coverage (PLC) as the centerpiece of farm program safety net. The House farm bill allows for a one-time election of PLC vs ARC covering the 2019 -2023 crop years, while the Senate bill would permit farmers to change their election in the 2021 crop year following their 2019 election. The Senate bill also contains language to pave the way for legalization of industrial hemp by removing it from the federal list of controlled substances. States would be the primary regulators for the crop, and the bill also allows hemp researchers to apply for USDA competitive grants and hemp farmers to be eligible for federal crop insurance. The Senate bill also gave greater attention to programs that promote organic agriculture and local foods and increased trade promotion efforts. The controversial crop insurance and sugar programs come out of the farm bill debate in both chambers relatively unscathed. In reality, work requirement provisions as part of the Supplemental Nutrition Assistance Program (SNAP, better known as the food stamp program) remain the major difference between the two bills. The House farm bill contains eligibility requirements that able-bodied adults (ages 18 to 59), without children under the age of 6 to either work or participate in a free work training program for a minimum of 20 hours per week in order to receive SNAP benefits. The House bill limits SNAP eligibility to individuals with incomes that are no more than 30% above the federal poverty level. The Senate version contains no language addressing work requirements, instead focused on efforts to reduce fraud within SNAP. In recent farm bills, SNAP has accounted for 70 to 80% of total farm bill expenditures. Selected Ag Provisions of the House and Senate Farm Bills 1/

Similar to House Bill

Kentucky farmers overwhelmingly signed up for the ARC program (vs the PLC) program under the 2014 farm bill given the level of

projected payments and the established reference prices for PLC. In 2015, Kentucky farmers received $49.8 million dollars of ARC

payments (7.8% of net farm income) and $59.1 million (13% of net farm income) in 2016. Last October, the Kentucky Farm Service

Agency (FSA) indicated that 32,787 Kentucky farms that enrolled in safety-net programs established by the 2014 Farm Bill received

$90.5 million in 2017, which covered the 2016 crop year. Preliminary indications are that payments in 2018 for the 2017 crop will

be significantly lower due to the structure of the ARC program calculations. Given current and projected price levels, it appears

more farmers will give greater attention to the PLC program in future crop years if the current structure of the 2018 farm becomes

law.

Don’t Trip on Tr iple -19 There are wrong ways to do right things. Repeated use of products like triple-10 (10-10-10) or triple-19 (19-19-19) on hay fields can ultimately make that field unresponsive to the fertilizer that is applied. Don’t get me wrong, fertilizing is a ‘right’ thing. People that fertilize their pasture and hay fields have a special place in my heart. But here is why triple-19 can trip you up. The nutrients in a hay crop are 100% removed from the field, unless that hay is fed back in the same field. It takes 18 pounds of P2O5 and 50 pounds of K2O fertilizer to replace the nutrients in one ton of grass hay (Table 1). Using triple-10 or triple-19 alone to replace these nutrients is guaranteed to over-fertilize with P or under supply K.

Soils have very different abilities to supply P and K from the mineral parent material. This fact alone is one of the best reasons for a current soil test from hay fields. Repeated use of 200 or even 300 pounds of triple-19 on hay fields will drain the soil of potassium, such that the other fertilizer nutrients are ineffective. To understand why low K fertility limits other fertilizer benefits, you have to understand what is called the Law of the Minimum, which states that growth only occurs at the rate allowed by the most limiting factor.

Think of your field as a barrel and your yield as water. The height of each stave is the level of individual soil nutrients. If your ‘K’ stave is excessively short, your barrel will not hold much water. Low K means low yield in spite of how tall the P stave is. Fertilizing with adequate K affects more than yield. Potassium is directly involved in stomatal function. Stomates are the openings in leaves where water exits the plant; low K forages cannot effectively regulate water status in drought. Potassium directly affects winter hardiness, especially in legumes like alfalfa. Finally, plants with low K status are more prone to disease when stressed. Don’t let triple-19 trip you up. Get a current soil test, especially from hay fields, and apply the needed nutrients. Make a visit to your preferred vendor for fertilizer and tell them what you need. Getting a blended fertilizer that fits your needs may take some extra work on their part, but they can do it.
