2,4-D and Dicamba Found to Have Lethal and Sub-lethal Effects on Lady Beetles
As weeds develop resistance to glyphosate, GM crops resistant to the 2,4-D and dicamba are poised to enter the market. However, these herbicides and the formulations containing them can cause lethal and sublethal effects on beneficial insects.

Largest-Ever Study of GE Crops and Pesticide Use Finds Negative Environmental Impact in the U.S.
The largest-ever study on GE crops and pesticide use in the U.S. has found that adopters of GE glyphosate-tolerant soybean and maize have used increasingly more herbicides than non-adopters to deal with the proliferation of glyphosate-resistant weeds.
