Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
The International Pesticide Application Research Consortium (IPARC), previously known as the International Pesticide Application Research Centre and before that the Overseas Spray Machinery Centre (OSMC), has focused on pesticide application methods appropriate for smallholder farmers since 1955.
Many newer pesticides are derived from plants or naturally occurring substances (e.g.—nicotine, pyrethrum and insect juvenile hormone analogues), but the toxophore or active component may be altered to provide increased biological activity or stability. Applications of pesticides must reach their intended targets.
The three categories have a similar application process, but have different data requirements and review policies. Depending on the category of pesticide, the review process can take several years. After a pesticide is registered with the EPA, there may be state registration requirements to consider.
The biological activity of a pesticide, be it chemical or biological in nature, is determined by its active ingredient (AI - also called the active substance). Pesticide products very rarely consist of the pure active ingredient. The AI is usually formulated with other materials (adjuvents and co-formulants) and this is the product as sold, but ...
Pesticide application can artificially select for resistant pests. In this diagram, the first generation happens to have an insect with a heightened resistance to a pesticide (red) After pesticide application, its descendants represent a larger proportion of the population, because sensitive pests (white) have been selectively killed.
Trunk injection or endotherapy also known as vegetative endotherapy, [1] [2] [3] is a method of target-precise application of pesticides, [4] [5] [6] plant resistance activators, [7] or fertilizers [8] into the xylem vascular tissue of a tree with the purpose of protecting the tree from pests, or to inject nutrients to correct for nutrient deficiencies.
AOAC International's technical contributions center on the creation, validation, and global publication of reliable analytical test methods.Their areas of focus include, but are not limited to, safety of foods, beverages, dietary supplements, fertilizers, animal feeds, soil and water, and veterinary drugs.
