Can We Manage Dicamba Applications in 2018?
February 15, 2018
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.
Potential Off-Target Dicamba Movement from Corn Applications
February 15, 2018
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.
Preplant Tillage to Manage Glyphosate-resistant Common Ragweed
February 13, 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 on the Impact of Dicamba Micro-Rates on Non Dicamba-Tolerant Soybeans
January 10, 2018
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.
The Rise of Multiple-Resistance in Nebraska’s Weeds and Effects Of Dicamba Micro-Rates on Sensitive Crops
January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics on how to diversify weed control methods and modes of action to reduce potential development of resistance.
Dicamba Injury Symptoms on Sensitive Crops
June 28, 2017
Dicamba-resistant soybean, genetically engineered to provide resistance to dicamba and glyphosate, was made commercially available for the 2017 growing season. This article looks at potential dicamba injury to sensitive crops and plants.
Spraying the New Phenoxy Herbicide Formulations in Xtend and Enlist Soybeans Will Present Challenges
May 11, 2017
The new phenoxy herbicide formulations, including Enlist Duo™ (Dow), XtendiMax® (Monsanto), Engenia™ (BASF), and FeXapan™ (DuPont), offer growers new management options along with new application requirements. To alleviate problems related to applying new phenoxy herbicide formulations in soybeans as well as to increase herbicide performance, manufacturers have established application requirements. Here we discuss some of the key application factors to consider.
