Researchers report on a study to confirm the level of sensitivity of grapes and tomatoes to 1/10 and 1/100 of the label rate of dicamba. The studies were conducted with pot-grown grape and tomato plants during the summers of 2016 and 2017 at the Haskell Ag Lab.
With a delayed or compressed planting season, this week several growers asked whether they could immediately plant soybeans after a dicamba application. See how Extension Weed Scientist Amit Jhala replied.
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.
New RUP dicamba Q&A: Since I must record how and when the spray system cleanout was done, how should I do this when using the same RUP dicamba product on Xtend soybeans for multiple loads and/or over several days?
