There is Agro-climatic concern that the widespread use of dicamba-based herbicides in Dicamba-Tolerant (DT) soybeans can result in un-intended drift onto non-DT crops in nearby field due to windy conditions and volatility. New dicamba-based products such as Engenia® and XtendiMax® with Vapor Grip technology were developed to reduce volatility, however, they are not completely volatile-free. A study was conducted to evaluate the sensitivity of pot-grown grape and tomato to six micro-rates of three dicamba-based products (Clarity®, Engenia® and XtendiMax®) in 2016 and 2017, at Haskell Ag Lab, Concord (42.37oN, 96.68oW), NE, USA. The tested dicamba formulations negatively impacted growth of grape and tomato as measured by vine length and plant height respectively, as well as by plant biomass. About 2% of the label rate was high enough to cause 50% injury and reduction.. View More»
