Adsorption - CORRECT ANSWER: Adsorption is the binding of chemicals to soil
particles.
Pesticides that are strongly adsorbed (bound) are less likely to be carried from the
treated area by surface water or to leach through the soil; they may, however, be moved
readily by soil erosion.
Advantages and Disadvantages of B - CORRECT ANSWER: adv
-RTU
-attracts pest, dont need to cover huge area

disadv
-risk to children and pets
-may kill non-target wildlife
-requires careful placement/inspection
-dead vertebrate pests may cause odor problem
-must be removed when stops working
-may not always work if pest has other food sources
Advantages and disadvantages of C, LC, or WSC/WSL - CORRECT ANSWER: adv
-easy to handle, transport, store
