Pesticide use has brought only good things to humans d. Pesticide use is a relatively modern phenomenon 2. How can pesticide use result in a positive feedback loop? Product rotations, de-registrations, modes of action, oh my! Over time many pesticides have gradually lost their effectiveness because pests have developed resistance - a significant decrease in sensitivity to a pesticide, which reduces the field performance of these pesticides. For many reasons, the availability of pesticidal products that can be used in rotation against pests is decreasing. b. genetically changes (through natural selection) and is no longer affected by the chemicals. 4, no.
