11.1 Categories 1(a), 1(b), 2 & 4: Agricultural, Forest & Seed Treatment

11.1 Categories 1(a), 1(b), 2 & 4: Agricultural, Forest & Seed Treatment

[!NOTE] Read the regulation, not the brochure. Section 5 of 302 KAR 26:020 states, in its own words, what each category exam must test. Everything below begins with that language and then applies it to Kentucky conditions.

---

Category 1(a): Agricultural Pest Control - Plant

Section 3(1)(a) scope. Persons applying or supervising the application of pesticides in production of agricultural commodities including, for example, tobacco, peanuts, cotton, feed grains, soybeans and forage, vegetables, small fruits, tree fruits and nuts, grasslands, non-crop agricultural lands, and greenhouses.

Section 5(1)(a) competency. Practical knowledge of crops and the specific pests of those crops, plus practical knowledge concerning:

Kentucky's dominant Category 1(a) pest complexes are herbicide-resistant marestail, waterhemp, and Palmer amaranth in soybeans; corn rootworm and stalk borers in corn; foliar disease in wheat and double-crop soybean; and the specialty pest and residue rules of burley and dark tobacco.

Category 1(b): Agricultural Pest Control - Animal

Section 3(1)(b) scope. Persons applying or supervising the application of pesticides on animals - beef cattle, dairy cattle, swine, sheep, horses, goats, poultry, and livestock - and to places on or in which animals are confined.

Section 5(1)(b) competency. Practical knowledge of agricultural animals and their associated pests, and the relative hazards associated with such factors as formulation, application technique, the age of animal, stress, and extent of treatment. Practical knowledge is also required concerning specific pesticide toxicities and residue potentials because host animals will frequently be used for food.

The five hazard factors the regulation names are the exam's structure for this category:

Layered on top are the two residue clocks from Section 10.1 - the slaughter withdrawal interval and the milk discard period - and the commingling problem that makes a bulk milk tank so unforgiving. Premise treatments in confinement housing add ventilation, feed and water protection, and manure-handling considerations.

[!WARNING] Category 1(b) is Animal, not Agricultural Fumigation. Stored-grain and commodity fumigation is Category 13 (Non-Soil Fumigation) and pre-plant soil fumigation is Category 12. The old Category 1(b) Agricultural Fumigation was converted into those two by Section 10(2) of the 2022 regulation.

Category 2: Forest Pest Control

Section 3(2) scope. Persons applying or supervising the application of pesticides in forests, forest nurseries, and forest seed producing areas.

Section 5(2) competency. Practical knowledge of the types of forests, forest nurseries, and seed production within the department's jurisdiction and the pests involved, including:

• The cyclic occurrence of certain pests and specific population dynamics as a basis for programming pesticide applications - forest pests run on multi-year cycles, so the decision is a program decision, not a single-season decision;
• The relevant harmful organisms and their vulnerability to the pesticides to be applied;
• How to determine when pesticide use is proper;
• Selection of application method and proper use of equipment to minimize non-target exposures;
• Appropriate responses to meteorological factors and adjacent land use;
• The potential for phytotoxicity across a wide variety of plants to be protected, for drift, for persistence beyond the intended period of pest control, and for non-target exposures.

Kentucky forest work centers on invasive woody plant control (bush honeysuckle, tree-of-heaven, kudzu, autumn olive), bark beetle and defoliator management, forest nursery and Christmas tree production, and herbicide site preparation and release. The adjacent-land-use requirement is not abstract in Kentucky: forest tracts sit next to tobacco, gardens, and headwater streams, and the Kentucky Agriculture Water Quality Act reaches silviculture as well as agriculture.

Category 4: Seed Treatment

Section 3(4) scope. This category "applies to commercial applicators using or supervising the use of restricted use pesticides on seeds in seed treatment facilities." Note how narrow that is - it is a facility-based, restricted-use-based category.

Section 5(4) competency. Practical knowledge including:

• Recognizing types of seeds to be treated;
• The effects of carriers and surface active agents on pesticide binding and germination - the single most technical requirement in the category, because a coating that binds poorly dusts off in handling and a coating that binds too aggressively can impair germination;
• The hazards associated with handling, sorting and mixing;
• Misuse of treated seed;
• The importance of proper application techniques to avoid harm to non-target organisms;
• Proper disposal of unused treated seeds.

Two facts drive the practical exam questions:

1. Treated seed must never enter food or feed channels. Treated seed is dyed a conspicuous, contrasting color specifically so that it cannot be mistaken for commodity grain. Feeding treated seed to livestock or delivering it to an elevator is a serious violation and a food-safety event.
2. Dust-off is the non-target pathway. Abraded seed treatment dust carried on planter exhaust is a recognized route of pollinator exposure, which is why fluency agents, planter modifications, and handling discipline matter.

Disposal of surplus treated seed follows the label - typically planting it at a labeled rate on a labeled site, or disposal as pesticide waste. It is never landfilled casually, burned, or dumped, and in Kentucky it is never put in a sinkhole.

Exam Alert: For 1(a), memorize the seven Section 5(1)(a) knowledge areas. For 1(b), memorize the five hazard factors - formulation, technique, age, stress, extent - plus the residue clocks. For 2, the distinctive phrase is cyclic occurrence and population dynamics as the basis for programming applications. For 4, the distinctive phrase is carriers and surface active agents affecting binding and germination, and the distinctive rule is that treated seed never enters food or feed channels.
