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.
A herbicide label is a legal document providing important information about a herbicide, its appropriate use, and the precautions needed to avoid off-target movement and to protect environmental quality. It can also help you achieve the most efficient and sustainable application. Learn more about what to watch for on herbicide product labels.
To avoid some of the off-target dicamba injury that occurred in 2017, new label requirements and application recommendations are being made for 2018. This is an article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics.
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.
In many areas fall herbicide applications were delayed due to the late harvest. Applications can still be effective, depending on weeds present, temperature, rate of herbicide and additives used. The article offers recommendations for these late-fall applications and their importance, particularly for control of herbicide-resistant marestail.
Forage cover crops after corn or soybean have restrictive plant-back restrictions. These two Nebraska Extension resources offer further information on what to check before planting cover crops this fall.
