Should the cold spring delay cover crop termination? Growers walk a fine line between growing cover crops long enough to get the biomass they want without reducing yield in the following grain crop. This discussion from an agronomist, entomologist and weed scientist looks at various factors to consider.
Finding a good time for burndown herbicide applications has been a little tricky this spring, given the below-normal temperatures the first half of April and intermittent snow and rain, all of which can decrease herbicide efficacy. Checking the forecast can help identify an optimal window for application.
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.
Even with new dicamba-resistant soybeans, pre-emergence, residual herbicides are needed to mitigate yield loss due to weed competition, provide a longer time for soybean to establish, and reduce selection pressure for weeds resistant to post-emergence herbicides.
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.
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.
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.
