Much like glyphosate, these new varieties of GE corn and soybeans are set to usher in dramatic increases in 2,4-D. Dow AgroSciences produces these new GE crops under the brand name Enlist which will be stacked with glyphosate resistance. The "pesticide trap" is when farmers are forced to use more and more chemicals to control insects and weeds that are resistant to pesticides. MOA is the specific process by which an insecticide kills an insect, or inhibits its growth.

Recommendations for successful resistance management (Modern Crop Protection Compounds, Wolfgang Kramer and Ulrich Schirmer): To prevent the pest from building-up resistance to the chemical, you should not use chemicals from the same resistance group over and over. herbicide-resistant weeds are rapidly increasing. We believe that managing the development of pesticide resistance, in conjunction with alternative pest-management strategies and integrated pest management (IPM) programs, is an important part of sustainable pest management.

The neonicotinoids are a class of insecticides with a common mode of pesticidal action that affects the central nervous system of insects, causing paralysis and death. Insects develop this type of resistance by expressing multiple resistance mechanisms. Pests can develop resistance to the pesticides if the effectiveness is decreased. Which of the following categories includes all the others? Development of organic insecticides, such as DDT, has given little hope that insecticide resistance was an issue of the past.
