2) Earlier this week, I had some questions about peanut fungicide tank-mixes with Cobra and Strongarm. Here is what I know based upon some older data (not much though):
a) Cobra + Fungicides: Results from a field trial conducted in 2005 suggested no problems with Cobra + Bravo or Folicur. When Abound was tank-mixed with Cobra, Florida beggarweed control was reduced by 12%. When Headline was tank-mixed with Cobra, annual morningglory control was reduced by 8%. All treatments also included COC @ 1% v/v. Peanut injury was not increased with Cobra + fungicide tank-mixtures. All treatments were applied to Georgia Green at 28 DAP.
b) Strongarm + Fungicides: From another field trial conducted in 2005, annual morningglory control was not reduced when Strongarm was tank-mixed with Bravo WS, Abound, Folicur, and Headline. Florida beggarweed control with POST applications of Strongarm was poor in general (<70%) and control was further reduced by 15% when tank-mixed with Headline. NIS @ 0.25% v/v was included with all treatments. Peanut injury was not increased with Strongarm + fungicide tank-mixtures. All treatments were applied to Georgia Green at 23 DAP.
3) Someone asked me about the tolerance of soybeans to dicamba drift. As with most drift situations, it all depends upon rate and stage of growth. Generally, soybeans are less tolerant of dicamba drift at reproductive stages of growth.
