NYSDEC PESTICIDE APPLICATORS TEST PAPER 2025/2026
ANSWERS AND QUESTIONS GRADED A+
✔✔Calibration - ✔✔Adjustment in size psi or other aspects in order to improve accuracy
✔✔Canister Respirator - ✔✔A respirator with a large filter that is contained in a canister
worn on belt or chest. 4..
✔✔Carbamates - ✔✔A group of insecticides that affects insects and people by
interfering with the nervous system. 4.
✔✔Carrier - ✔✔The material into which pesticides are mixed for application
✔✔cartridge respirator - ✔✔A respirator with a filter cartridge that attaches to the mask
of the respirator.
✔✔Check Valve - ✔✔Automatic valve that permits liquid flow in only one direction.
✔✔chemical control - ✔✔Using pesticides
✔✔chemical incompatibility - ✔✔Activity of a pesticide mixture is different than of the
products were applied separately. 2.
✔✔Cholinesterase - ✔✔An enzyme that occurs in the blood and nervous system.
Organophosphate and carbamate interfere with this function. 4.
✔✔chronic effect - ✔✔an effect that results from long,term exposure to low levels of
toxin.
✔✔Closed handling transfer system - ✔✔A mechanism that moves pesticide into spray
tank with out applicator coming into contact.
✔✔common name - ✔✔The official name of an active ingredient accepted by USEPA
✔✔Compatibly agents - ✔✔Adjuvants used to allow effective mixing of pesticde(s) with
fertilizers.
✔✔Compatibile - ✔✔Two or more pesticides safely mixing together
✔✔complete development - ✔✔Life cycle of an insect that passes the 4!stages of egg,
larva, pupa and adult.
✔✔Cone-Spray Nozzle - ✔✔Designed to produce circular spray pattern
, ✔✔Containment system - ✔✔Procedures and facilities established to contain pesticides
inadvertently released during mixing loading or in an emergency. 4.
✔✔cross resistance - ✔✔Resistance to a pesticide that the pest has not previously
been exposed to, but that has a mode of action similar to pesticide that allowed
resistance to develop.
✔✔cultural control - ✔✔Healthy plants= no pesticides needed.
✔✔damage threshold - ✔✔The maximum damage from infectious plant disease that a
crop can sustain without yield loss.
✔✔degradation - ✔✔The breakdown (decomposition) of a pesticide into a simpler
compound that is usually non toxic. Can be chemical physical or biological.
✔✔Particle Drift - ✔✔the airborne movement of particles such as pesticide dusts and
pesticide-contaminated soil from the application site
✔✔Vapor drift - ✔✔movement of pesticide vapors caused by chemical volatilization of
the product. After contact of plant. 4 & 5
✔✔Drift reduction additives - ✔✔Thickening adjuvant to increase droplet size and
reduce drift
✔✔Droplet Spectrum - ✔✔The range in droplet size that a spray nozzle produces.
✔✔Early Preplant (EPP) - ✔✔Application before crop is planted.
✔✔Economic Injury Level (EIL) - ✔✔the pest population density that causes losses
equal to the cost of control measures
✔✔Economic (or action) threshold (ET) - ✔✔The point which a control measure is
justified to prevent reaching economic injury level.
✔✔Effective Swath Width - ✔✔The span of spray or granules with enough pesticide to
control the pest., amount of overlap essentially
✔✔endemic - ✔✔A disease present every year but does not crest significant damage.
✔✔endocrine disruptors - ✔✔Chemicals that disrupt normal hormone functions
✔✔Even Flat-Fan Pattern - ✔✔A thin sheet of spray with uniform deposits
✔✔Fetoxic - ✔✔Causes harm to unborn fetus.
