Adopt all non-chemical techniques known to control or suppress pest populations, including biological sprays such as Bts, resistant varieties, within-eld refuges (untreated areas) and crop rotation. How quickly pesticide resistance develops depends on: the frequency of use, the mechanisms of resistance, the genetics of the resistance mechanism, the size of the gene pool and how quickly the organisms reproduce. This increase in glyphosate-resistant crops has led to an increase in herbicide use, herbicide-resistant weeds (also known as superweeds), and numerous other environmental and human health impacts. These rare resistant individuals can reproduce and pass on their resistance to the offspring. All of the neonicotinoids were registered after 1984 and were not subject to reregistration. However, there are some cases where even this strategy has resulted in resistance to both pesticide groups. In terms of agriculture, pesticides have lead to _____ for consumers.
