Survey Shows Dicamba may Reduce the Effectiveness of Junglerice Controls
In recent years, junglerice has become a significant problem in dicamba-resistant cotton and soybean crops. In Tennessee, for example, growers routinely find populations of the weed that escape applications of dicamba plus glyphosate and/or clethodim - two "go to" herbicide controls.
 
A recent survey featured in the journal Weed Technology explores the prevalence of junglerice in cotton and soybean crops and whether dicamba interferes with the effectiveness of herbicides used to control the weed.
 
In a two-year study, researchers from the University of Tennessee found junglerice was the most prevalent weed to escape treatment in the dicamba-resistant cotton and soybean fields. It was found 76 percent of the time in cotton and 64 percent of the time in soybean.
