Glyphosate Resistance in Soybeans

Many weeds have developed glyphosate resistance in the past few years. Many producers who use Roundup Ready soybeans have a temptation to rely on glyphosate products to control post-emergent weeds, causing them to potentially become resistant to the chemical. If producers are unable to gain control over the weed, then weed competition will cause a significant yield loss.

Spring Dandelion Control In Soybeans

Dandelion has become much more of a problem as farming practices have changed. Less tillage and increased use of glyphosate resistant crops along with reduced use of residual herbicides have allowed some perennial weeds such as dandelion to prevail.

SDSU Research Shows Effects Of Volunteer Corn In Corn And Soybeans

In 2007, researchers at South Dakota State University indicated that volunteer corn is much less competitive in corn than soybean. The South Dakota study (Alms et al. 2007) evaluated the full season effect of a range of volunteer corn densities (800-14,000 plants/acre) on both corn and soybean and reported yield losses that ranged from 0% to 13% in corn and 0% to 54% in soybean.
