PESTICIDE APPLICATORS TEST PAPER 2025/2026
QUESTIONS WITH ANSWERS MARKED A+
✔✔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.
✔✔Filtering face piece respirators - ✔✔Particulate respirator l. Traps dust mists and
welding fumes but not organic vapors
✔✔flow meter - ✔✔Measures volume of liquid flowing through nozzle in a given time
usually as gallons per minute.
✔✔Foliar applied pesticides - ✔✔To foliage
✔✔formulation - ✔✔Saleable form of a pesticide
✔✔fruiting bodies - ✔✔Tiny sacs (pyenida or peritheca) produces by fungi that releases
reproductive spores
✔✔Fungi - ✔✔Causes rusts, smuts, mildew and lead spot
✔✔General Use Pesticide - ✔✔A pesticide that can be purchased and used by the
general public
✔✔glandular effects - ✔✔A change within an animal similar to that caused by hormone
produced by organs
✔✔growth regulators - ✔✔Control plant or insect growth
✔✔half-life - ✔✔Length of time for microbial and chemical process to degrade pesticide
to one half its original concentration.
