The frequency of resistant plants in the population increases, thus the population has evolved towards herbicide resistance. How do insects become resistant to pesticide? 4 points QUESTION 9 1. Resistance may develop to only a single insecticide. Microevolution is defined as changes in allele frequency that can be observed within a population. Scientists around the world have reported increased cancer risks in association with its use, especially for non-Hodgkins Lymphoma (NHL). Herbicides are the most widely used agricultural chemicals, and no new herbicide mechanism of action has been developed in the last 30 years, while herbicide-resistant weeds are rapidly increasing. The composition of the gene pool continually changes over time through a process called natural selection. All of the neonicotinoids were registered after 1984 and were not subject to reregistration.
