Regulatory oversight includes human health and environmental fate risk assessments as well as resistance-management risk evaluations. Integrating non-chemical approaches such as pheromone mating disruption and cultural controls can also help delay resistance. The enhancement of desired traits has traditionally been undertaken through conventional plant breeding. 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. this strategy represents, first published in 1962 the book silent spring helped to establish, the evolution of pesticides resistance resurgence and secondary pest outbreaks are only some if the problems that result from reliance on, a)Practices, creating a never ending pesticide treadmill requiring new pest-fighting strategies.
