◉ When do problems develop with turfgrass? Answer: When the
grass is unable to withstand environmental stress or when good
management cannot offset the effects of environmental stress
,◉ What are the steps of diagnosing a problem in turfgrass? (5)
Answer: Determine the kind of grasses involved
Find out why, if possible, the problem occurred
Determine if it can be corrected by management practices, soil
modification, or pesticides

Aesthetic
◉ What is an economic action threshold? Answer: Point at which
pest populations or environmental conditions indicate that pest
control action must be taken to prevent an economic loss
