Larry Steckel New research looks at why junglerice escapes are on the rise in soybean and cotton. A new study by the University of Tennessee Institute of Agriculture suggests dicamba is reducing the effectiveness of both glyphosate and clethodim to control junglerice. Featured in the journal Weed Technology, the recent study explores the prevalence of junglerice in cotton and soybean crops and whether dicamba interferes with the effectiveness of herbicides used to control the weed. "We found glyphosate plus dicamba mixtures reduced junglerice control by 25 percentage points compared with glyphosate alone,” said Clay Perkins, a member of the UTIA research team. “Clethodim plus dicamba provided 6.5 percent less control than with clethodim alone."
