What is an Adjuvant? What are the two types? - CORRECT ANSWER A
chemical that modifies a pesticide's physical properties and/or enhances its
performance.
1) Utility agent
2) Spray modifier
Utility agents - CORRECT ANSWER -Aid mixing in the spray tank
-Ex) Compatibility agents, pH buffering agent, anti-foaming agents
Spray modifiers - CORRECT ANSWER -Aid spray application & coverage
Drift reduction additives - CORRECT ANSWER Increase droplet size and reduce
drift
Surfactants - CORRECT ANSWER Help individual spray droplets spread out on
the treated surface
Stickers - CORRECT ANSWER Improve pesticide adherence to the treated
surface
Penetrants - CORRECT ANSWER Improve pesticide penetration into the treated
surface
When mixing two or more pesticides in the same spray tank, what steps and
considerations should you take to ensure a successful tank-mix? - CORRECT
ANSWER A. Pesticide compatibility
B. Are certain mixtures prohibited?
C. Consult technical staff (specialists or manufacturer)
D. Perform a jar test (if physical compatibility is a concern)
E. Add and thoroughly mix the products one at a time and in the proper order
What are the two types of incompatibilities? - CORRECT ANSWER 1) Physical
incompatibility
2) Chemical incompatibility
Physical incompatibility - CORRECT ANSWER Pesticides cannot be physically
mixed together
-May be related to the pH, Chemical composition, and/or temperature of the carrier
Chemical incompatibility - CORRECT ANSWER Altered activity of one or more of
the pesticides mixed together in a spray tank
Pesticides achieve useful pest control by their...(what two things?) - CORRECT
ANSWER A. Selectivity
B. Mobility
C. Residual activity
What are the two selectivities? - CORRECT ANSWER 1. Selective- Pesticides
control some related pests, but not others
ex) 2,4-D to control weeds in grasses
2. Non-selective- Pesticides control all related pests
ex) glyphosate to control all weeds along a fence row
What is pest resurgence? - CORRECT ANSWER A situation in which a pest
population, after having been suppressed, rebounds to numbers higher than before
suppression occurred
What are the two mobilities? - CORRECT ANSWER 1. Contact- Pesticides do
not move within the plant. Effective only where applied (local surface)
ex) Daconil fungicide, etc.
2. Systemic- Pesticides move within the plant. Effective against pests or plant parts
that your application methods can't reach
ex) Merit, Roundup
