Research has shown that soybeans are about 200 times more sensitive to dicamba than corn is to glyphosate.
That means the odds growers will have to deal with dicamba injury in their soybeans at some point are greatly increased compared to other situations involving misapplication of herbicides in crops.
Dr. Jim Griffin, a retired weed scientist with the LSU AgCenter, discussed the work he and graduate research assistant Matthew Foster have been conducting on a model designed to help growers make decisions in response to dicamba injury.
They both spoke during a session at the Louisiana Agricultural Consultants Association’s Louisiana Agricultural Technology and Management Conference, which was held in Marksville, La., earlier this year.
