by pests, AND volatility? (all four!) - ANSWER-temperature
What are the drawbacks of planting transgenic crops on a pest management
plan? - ANSWER-increase in pesticide usage, emergence of secondary pest
,problems, repeated use of the same pesticide in an area, and weeds that develop
resistance to same pesticide as the crop

plants are physically stressed by overwatering or nutrient deficits
Using transgenic plants without employing other IPM methods may increase a
pest's... - ANSWER-resistance to the inserted genes
Why do integrated pest management programs work better than programs
relying on just one management method? - ANSWER-a diversity of approaches
to managing pests increases the long-term effectiveness of each individual
control measure

ANSWER-tomato, alfalfa, and cotton
What must you do to protect surface water near the field where you are applying
a pesticide? - ANSWER-create a buffer zone near the water, and avoid spraying
in that zone
When a pest has several distinct mechanisms to withstand pesticide chemicals,
allowing them to tolerate several classes of pesticides that are not related to
each other chemically, they have developed . . . - ANSWER-multiple resistance
How can you tell if pesticide coverage is adequate in an area? - ANSWER-
check foliage for visible residue
