QAL & QAC UPDATED ACTUAL Exam
Questions and CORRECT Answers
Pesticides are - CORRECT ANSWER - Substance that control pests, they may be either
naturally-occurring compounds like sulfur or synthetic (i.e. man-made) compounds like the
insecticide malathion.
Pesticides are - CORRECT ANSWER - 1. Compounds that control pests
2. Plants defoliants
3. Plant growth regulators
4. Adjuvants
Plant defoliants are in - CORRECT ANSWER - use to remove leaves from plants, most
often to aid in the harvest of crops.
Plant growth regulators (PGR) are - CORRECT ANSWER - used to alter plant growth or
development.
Adjuvants - CORRECT ANSWER - a product added to the tank to improve a pesticides
performance.. it may improve the wetting ability of the mixture, increase the pesticides
penetration in to plants or insects tissue or may prevent pesticide drift.
Although adjuvants have no significant pesticidal activity, DPR regulates them in almost the
same way it regulates pesticides.
examples of adjuvants - CORRECT ANSWER - Surfactants... helps pesticides get inside
target plants like weeds.
Stickers... helps the pesticide stay on the target plant's leaves.
Buffers... makes acidic or alkaline mix water more neutral.
, Drift control agents or deposition aids... Prevent spray drift.
Defoamers... reduce tank-foaming
Spreader- stickers
Pesticide Formulations - CORRECT ANSWER - A mixture of 2 or more compounds.
Pesticides formulations are made up of an active ingredient and 1 or more inert ingredients.
Active ingredients have pesticidal activity.
Pesticide Formulations - CORRECT ANSWER - Liquids- High compatibility with other
pesticides. No agitation needed. BUT... they can be a splash hazard, and can be easily absorbed
through the skin.
Wettable powders- Are usually very compatible with other pesticides. BUT... they can be a
inhalation hazard. Because they are not soluble in water they can be abrasive to equipment and
they usually require agitation.
Soluble powders- Are similar to the wettable powders, except they dissolve more easily in water.
for that reason, they're not as abrasive to equipment and they usually require agitation.
Emulsifiable concentrates- these pesticides/petroleum solvents mixtures are formulated with an
emulsifier that helps the formulations with water. they penetrate plant tissue. BUT... they are
easily absorbed through human skin, they pair a significant eye hazard to handlers, and they
require agitation in the mix tank. They can be phytotoxic to plants.
Flowables- These pesticide formulations are made of finely ground pesticide particles with a
liquid carrier and an emulsifier. They are easy to handle and apply. BUT... they require tank
agitation and contribute to equipment wear.
