Researchers report on a study to confirm the level of sensitivity of grapes and tomatoes to 1/10 and 1/100 of the label rate of dicamba. The studies were conducted with pot-grown grape and tomato plants during the summers of 2016 and 2017 at the Haskell Ag Lab.
If you're considering planting winter wheat next fall, be sure to review the corn and soybean herbicide programs you plan to use this spring to avoid rotation restrictions that would limit your cropping options.
Results from a 2017 weed management trial on glyphosate-resistant ragweed indicated two applications were often more efficient and cost effective than either three applications or one application of herbicide.
Thoroughly cleaning your sprayer both before and after applying dicamba is required and can help reduce the potential for off-target damage. Check these recommended practices and see what research at Mississippi State University found when testing sprayer hoses.
Factors leading to dicamba injury and how growers will need to practice best management practices with all dicamba applications in 2018 to help reduce injury to susceptible crops and other plants. This article discusses key practices to implement.
While the new soybean dicamba herbicides were often blamed for injury to sensitive plants in 2017, a deeper look at the timing of injury and the weather conditions at those times suggests dicamba applications in corn may have contributed to plant injury in many areas. Increased management for all dicamba applications will be needed in 2018.
Nebraska university weed scientists conducted research in 2017 to identify the effect of preplant tillage on weed emergence in an effort to develop an integrated weed management plan to control glyphosate-resistant weeds. Here's what they found.
Research at the university's Haskell Ag Lab at Concord in 2016 and 2017 studied the effects of microrates of two dicamba products applied at one of three soybean growth stages. The trials showed that non-dicamba tolerant soybeans were sensitive to even very low micro-rates of Engenia and XtendiMax; response varied according to amount and growth stage, with exposure at later stages having less effect.
