Botany and PlantingPotato—Solanum tuberosum, Solanaceae
CultivarsThe University of Florida Potato Variety Evaluation Program screens new germplasm from public and private breeding programs and identifies the most promising cultivars for commercial potential, considering broad adaptability to Florida climate and conditions and market purpose: processing, fresh-market, and specialty-type varieties. The Florida Potato Variety Trial Report is avail-able at https://hos.ifas.ufl.edu/extension/variety-trials/. A summary of the most popular potato clones for Florida is presented below. Key reference: total yield: high >300 cwt/A, medium-high 250–299 cwt/A; medium 200–249 cwt/A; low-medium 150–199 cwt/A. Tuber specific gravity (SG): high >1.075, medium-high 1.070–1.074, medium 1.065–1.069, low <1.064.
1. Chipping TypesAtlantic. Mid-season, high yield, high SG. Mostly round; shallow eye depth; tan skin color; cream flesh; good appear-ance; susceptible to internal heat necrosis and hollow heart. https://edis.ifas.ufl.edu/publication/HS1278

Table 5. Nonfumigant nematicides for potatoes in Florida.Product Broadcast or overall rates Row rates
Per acre Per 1000 sq ft Per acre, 36” row spacing Per 1000 ft of row, any row spacing
Mocap 15G (a.i. ethoprop) 40 to 60 lb 0.9 to 1.4 lb 20 lb 1.4 lb
Mocap EC* (a.i. ethoprop) 1 to 1.5 gal 2.9 to 4.4 fl oz 2 qt 4.4 fl oz
Vydate C-LV** (a.i. oxamyl) --- --- 1 to 2 gal 9.8 to 19.5 oz
Nimitz (a.i. fluensulfone) All applications must be incorporated either physically or via drip or overhead irrigation. Make preplant applications at a rate of 3.5 to 7 pints (56.0 to 80.0 fl oz) per acre, a minimum of seven days before planting. Do not plant any unlisted crops into treated land for 365 days after application of the product. Do not apply more than one application per crop and no more than 112 fl oz of product per acre per year (365 days). Provides control only for nematodes. Growers applying Nimitz must consult the product label to observe the plant-back (recropping) intervals for a variety of leafy vegetables and brassica crops, onions, bananas, sugarcane, and other crops.
Velum (a.i. fluopyram) Apply max 6.84 fl oz/acre using overhead chemigation equipment. Do not apply more than 13.7 fl oz of Velum (0.446 lb fluopyram) per acre per year regardless of formulation (Velum or Luna) or method of application (soil or foliar). Do not apply within 7 days of harvest. For soil application, to limit the potential for development of disease resistance to this chemical class, the first foliar fungicide application after Velum should be a product from a different FRAC group.
*Do not apply Mocap in furrow, because it can cause crop injury when in contact with the seed piece. Do not apply Mocap where sorghum will be grown during the same year, because its residual activity may cause serious injury to sorghum. Mix into the top 2 to 4 inches of soil. Do not exceed 9 lb a.i./A Mocap 15G and 12 lb a.i./A for Mocap EC. **Vydate C-LV has registration for nematode suppression in potatoes as an in-furrow and foliar treatment program only. Each application of Vydate C-LV should be applied in a minimum of 20 gals of water per acre, the spray solution water always buffered to a pH of 5.0 or lower. Do not apply more than 2.4 gallons (9 lb a.i.) per acre per season or make more than 8 applications of Vydate C-LV per crop; the last application should be made at least 7 days prior to harvest.
Mocap and Vydate are insecticide-nematicides; Velum is a fungicide-nematicide; Nimitz is a true nematicide. Unlike fumigants, these products are not volatile and will move through the soil via water; depending on the water solubility, these products will have different recommendations as for how to best apply them (see specific label recommendations); when nematode pressure is high, they may not be as consistently effective against root nematodes as the fumigants.

Telone II2,3 9 to 12 gal 26 to 35 For any row spacing, application rates given may be concentrated in the row but shall never exceed the labeled maximum for broadcast applications. Consult the product label for additional detail.
Telone C-172,3 10.8 to 17.1 gal 31.8 to 50.2 For any row spacing, application rates given may be concentrated in the row but shall never exceed the labeled maximum for broadcast applications. Consult the product label for additional detail.
Telone C-352,3 13 to 20.5 gal 38.2 to 60.2 For any row spacing, application rates given may be concentrated in the row but shall never exceed the labeled maximum for broadcast applications. Consult the product label for additional detail.
Pic-Clor 60 19 to 31.5 gal 57 to 90 For any row spacing, application rates should never exceed the labeled maximum for broadcast applications. Consult the product label for additional detail.
Chloropicrin 99% 150–350 lb - For any row spacing, application rates should never exceed the labeled maximum for broadcast applications. Consult the product label for additional detail.
Vapam HL 75 gal - For drip or in-row chisel fumigation, consult product label for proportionately reduced overall rates, drip concentration, and flow-modifying directions and procedures.
KPam HL 60 gal - For drip or in-row chisel fumigation, consult product label for proportionately reduced overall rates, drip concentration, and flow-modifying directions.
Allyl isothiocyanate (AITC) Dominus
40 gal - For drip or in-row fumigation and crop termination, consult product label for proportionately reduced overall rates, drip concentration, and flow-modifying directions
1Gallons/acre and fl oz/1,000 feet provided only for mineral soils. Higher rates may be possible for heavier-textured (loam, silt, clay) or highly organic soils. 2All the fumigants mentioned are for retail sale and use only by state certified applicators or persons under their direct supervision. New supplemental labeling for the Telone products must be in the hands of the user at the time of application. See new label details for additional use restrictions based on soil characteristics, buffer zones, requirements for Personal Protective Equipment (PPE), mandatory good agricultural practices (GAPs), applicator training certification, and other new rate modifying recommendations. 3Higher application rates are possible in the presence of cyst-forming nematodes.
Rates are believed to be correct for products named, and similar products of other brand names, when applied to mineral soils. Higher rates are required for muck (organic) soils. However, the grower has the final responsibility to see that each product is used legally; read the label of the product to be sure that you are using it properly.
