A termiticide label calls for 4 gallons of finished dilution per 10 linear feet of trench for each foot of depth. The trench around a slab home is 180 linear feet long and 1 ft deep. How much finished dilution is needed?
Answer in gallons.
Show the answer
72 gallons
Units of 10 linear feet = 180 / 10 = 18. Volume = 18 x 4 gallons x 1 ft of depth = 72 gallons.

In IPM, the action threshold is the:
- Highest rate permitted by the label
- Pest level at which control is justified
- Number of sprays allowed in a season
- Point where the pest has been eliminated
Show the answer
B. Pest level at which control is justified
The action threshold is the pest density or damage level at which treatment is needed to prevent unacceptable injury or loss. Below it, monitoring continues without treatment.
