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
Economic Injury Level -ANSWER-break- even point at which the cost of pest control equals
the revenue loss caused by a pest.
Aesthetic Injury Level -ANSWER-number of pests that might cause enough damage to the
appearance of a plant to warrant the cost of control
Scouting -ANSWER-Regularly monitoring pest populations and plant or crop conditions.
Could be the owner, maintenance technician, or grower.
What is the Goal of IPM? -ANSWER-To optimize, NOT maximize pest control
