5 Control Methods - ansCultural Control, Mechanical Control, Biological Control, Preventative Control,
Chemical control
Active ingredient - anspart of the formulation that is effective against the targeted pest
Adjuvants - anschemical that modifies a pesticide's physical properties and/ or enhances its performance
Aesthetic Injury Level - ansnumber of pests that might cause enough damage to the appearance of a
plant to warrant the cost of control
antagonism - ansDecreased activity or effectiveness
Band applications - ansTreat only a narrow strip over or alongside a row of desirable plants
Biological control - ansUses living organisms to reduce pest populations to economically acceptable
levels. EX: predators, parasites, pest diseases
Broadcast applications - ansTreat the entire area or field
Buffering agents - ansmay be added to reduce pesticide inactivation due to the pH of the carrier
chemical control - ansHerbicides, insecticides, fungicides, repellents, fumigants
contact pesticides - anscontrol by direct contact with the pest
Cultural control - ansimproves plant health so that they plants are able to compete better against pests.
EX: soil preparation, fertility, proper planting, plant selection, crop rotation, mulching, mowing
Directed Postemergence - ansLess- selective herbicides are directed away from the crop and onto the
weeds to minimize crop injury
Drift reduction additives - ansthickening agents that increase the droplet size and reduce spray drift.
Early Preplant (EPP) - anspesticides are applied several weeks before a crop is planted
Economic Injury Level - ansbreak- even point at which the cost of pest control equals the revenue loss
caused by a pest.
emulsions - ansmixtures in which one liquid is suspended as tiny drops in another liquid.
Federal insecticide, fungicide, and rodenticide act (FIFRA) - ansApproved in 1947. It provides a
framework for pesticide registrations an is the pesticide users assurance that the product, if used correctly
will provide some helpful service without endangering the user, other persons, or the environment
formulations - ansSalable forms of pesticide, including active and inert ingredients.
fumigants - anssubstances or mixtures of materials that produce gas, vapor, fumes, or smoke intended to
control pests.
Hydraulic agitatoin - anssome of the solution circulates through the pump and back into the tank to mix
the solution
Inert ingredient - ansdoes not have a direct effect on the pest
Mechanical control - ansPhysically eliminates the pest. EX: Cultivating, pruning, hoeing, weed pulling,
mowing, hand picking
,Pesticide Applicator Test 2023 Questions and Answers Verified Answers
nonselective (broad- spectrum) pesticides - anscontrol nearly all related organisms
Pest - ansany insect, mite, rodent, nematode, fungus, weed, or other organism that is injurious to humans
or their structures, or to plants, or animals of interest to humans.
Pesticide - ansany chemical used to destroy, prevent, or control any form of like declared to be a pest
Postemergence (PoE - ansPesticides are applied to the foliage of plants
Preemergence (PrE) - anspesticides are applied during or soon after planting but before weeds emerge
Preplant incorporated (PPI) - anspesticides are applied prior to planting and worked into the soil
preventative control - ansHelps prevent the entry and spread of pests. EX: quarantines, inspections,
certified seed
residue - anspesticide or its breakdown products that remain in or on plants or animals or in the soil after
treatment
Resistance - ansdevelop s when a few individuals in a pest population survive a pesticide treatment
because of their slightly different genetic makeup
resurgence - ansoccurs when these predator or parasite populations rebound more slowly than the target
pest
Scouting - ansRegularly monitoring pest populations and plant or crop conditions. Could be the owner,
maintenance technician, or grower.
selective pesticides - anscontrol certain pests with little or no injury related to organisms
spot applications - ansTreat only a portion of the total area and are used to control pests that are grouped
or clustered
Stickers - ansUsed to increase the adherence of the chemical to the treated surface, thus increasing its
persistence, particularly under adverse weather conditions
Surfactants (spreaders or wetting agents) - ansSurface- action agents that decrease the surface tension
of water, allowing the water carrier to spread over the surface rather than forming droplets
synergism - ansincreased activity or effectiveness
Systematic pesticides - ansmove within the plant or animal from the site of uptake to other parts of the
plant or animal
tolerance - ansamount of pesticide residue that may legally remain on or in the food or feed crop when
harvested
Two general types of ingredients - ansActive, Inert
What is the Goal of IPM? - ansTo optimize, NOT maximize pest control
5 Control Methods - ansCultural Control, Mechanical Control, Biological Control, Preventative Control,
Chemical control
