Herbicide resistant barnyardgrass in Iran and Turkey

Characterization of Herbicide- Resistant Biotypes of Barnyardgrass

Barnyardgrass (Echinochloa crus-galli) biotypes, resistant to different herbicides, have been reported. An experiment was conducted to compare the growth characteristics of various barnyardgrass biotypes, (i.e., propanil-resistant from Poinsett County, Ark., quinclorac-resistant from Louisiana., quinclorac/propanil-resistant barnyardgrass from Craighead County, Ark., and susceptible barnyardgra...

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...

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...

Herbicide Resistant Weeds and Crops

Modern herbicidal weed control often exploits physiological differences among plants and takes advantage of herbicide tolerance or resistance in crop plants to bring about the selective removal of susceptible weeds. The Weed Science Society of America defines herbicide tolerance as “the inherent ability of a plant to survive and reproduce after herbicide treatment” which suggests that herbicide...
