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.
With current corn prices and the limited availability of perennial grass, some producers are asking themselves if growing forages on cropland might be the answer to feeding the cow herd. A webinar to address these questions in addition to showing economic examples will be held Tuesday evening, February 13, from 6:00-7:30 p.m. CST.
In summer 2017, 312 Nebraska farmers from 60 counties responded to a survey on their perception on dicamba use in Xtend soybeans. The survey asked about outcomes of applying dicamba in Xtend soybeans and perceived injury in non-Xtend soybeans.
A review of multiple research studies indicates that where moisture is not limited, residue removal can result in no yield reduction to yield increases for the subsequent crop. However, long-term residue removal has been shown to affect other production factors and it's recommended that even in minimal erosion areas, removing residue does impact other production factors and it's recommended that 2.4 tons/acre of residue be left in the field.
Corn residue has a number of uses and thus its value as well as its impact on other systems may need to be estimated when evaluating post-harvest options. This article looks at how to estimate the nutrient value of the residue and potential impacts to the soil from removing the residue, based on Nebraska research.
