Products of science:Technology (all correct answers):1.C (To improve how people live) 2. Worldwide, more than 600 species of pests have developed some level of pesticide resistance. The hybrids were sterile, and microscopic observation of their pollen mother cells showed no chromosome pairing. The U.S. Department of Agriculture, the federal agency with responsibility for regulating pesticides before the formation of the U.S. Environmental Protection Agency in 1970, began regulatory actions in the late 1950s and 1960s to prohibit many of DDT's uses because of mounting evidence of the pesticide's declining benefits and environmental and Where larval stages are being controlled, target younger larval instars where possible because these are usually much more susceptible and therefore much more eectively controlled by insecticides than older ones. c. arithmetic, pioneer The pesticide type known as Botanicals are more specifically referred to as .

PRN 2017-1, Guidance for Pesticide Registrants on Pesticide Resistance Management Labeling offers general guidance on resistance management labeling for all conventional agricultural insecticides, fungicides and herbicides. Integrating non-chemical approaches such as pheromone mating disruption and cultural controls can also help delay resistance.

A .gov website belongs to an official government organization in the United States. Over time, many pesticides have gradually lost their effectiveness because pests have developed resistance which can be described as a significant decrease in sensitivity to a pesticide. The first step in this process is to identify desirable traits, such as flavor, color, tolerance, or resistance to a pest.
