Pesticide Types & Formulations Flashcards

A pesticide label states the formulation is an 'EC.' What does this abbreviation stand for?

Answer: Emulsifiable Concentrate

EC stands for Emulsifiable Concentrate, a formulation in which the active ingredient is dissolved in an organic solvent with an emulsifier added.

Which class of pesticide is used primarily to control fungal diseases on crops?

Answer: Fungicide

Fungicides are pesticides that inhibit or kill fungi, protecting crops from diseases like blight, mildew, and rust.

What is a key disadvantage of dust (D) formulations compared to liquid sprays?

Answer: Dusts are highly prone to drift and off-target movement

The fine particles in dust formulations are very light and easily carried by wind, making precise application difficult and increasing off-target risks.

Systemic pesticides are unique because they:

Answer: Are absorbed and move through the plant's vascular system

Systemic pesticides are taken up by the plant and translocated through its tissues, making all parts of the plant toxic to pests.

Which fumigant application method involves covering treated soil with a tarp after application?

Answer: Tarped fumigation

Tarped fumigation retains the gaseous fumigant in the soil by sealing it under a tarp, increasing efficacy and reducing atmospheric escape.

Adjuvants are added to pesticide formulations or tank mixes primarily to:

Answer: Improve application characteristics such as spreading, sticking, or penetration

Adjuvants enhance the performance of pesticide applications by improving coverage, adhesion, or uptake without being pesticides themselves.

Rodenticides used in bait formulations are categorized as which type of pesticide based on their target pest?

Answer: Rodenticide

Rodenticides are pesticides specifically designed to kill rodents such as mice, rats, and voles.
