Control of Herbicide-resistant Volunteer Corn in Herbicide-resistant Soybean

Glyphosate-resistant corn and soybean are grown in rotations in the Midwest, including Nebraska. Volunteer corn is a problematic weed in soybean fields because it causes harvest problems, reduces yield and seed quality, and potentially harbors insects, pests, and diseases. Several pre-packaged herbicides have been registered in soybean in recent years, but response of volunteer corn to these he...

Do Environmental Effects of Herbicide-Resistant GM Plants Differ from Effects of Other Herbicide Resistant Plants?

Genetic modification of crop plants has promoted concerns about potential environmental effects of this new technology. In this essay, I will discuss the environmental effects of genetic modification of crop plants using herbicide resistance as an example. Considering herbicide resistance as an old agricultural trait, it is difficult to find any reason to assess the environmental risks of genet...

Mechanism of Sulfonylurea Herbicide Resistance in the Broadleaf Weed, Kochia scoparia.

Selection of kochia (Kochia scoparia) biotypes resistant to the sulfonylurea herbicide chlorsulfuron has occurred through the continued use of this herbicide in monoculture cereal-growing areas in the United States. The apparent sulfonylurea resistance observed in kochia was confirmed in greenhouse tests. Fresh and dry weight accumulation in the resistant kochia was 2- to >350-fold higher in th...

Glyphosate and herbicide resistant plants

There is a common understanding that commercially traded formulations of glyphosate, such as Roundup, can be more toxic than glyphosate alone. Therefore, the EU has already taken measures to remove problematic additives known as POE tallowamine from the market. However, imports of genetically engineered plants resistant to glyphosate are exposed to high dosages of the herbicide in countries whe...
