Does Stylet-Oil have activity against Botrytis bunch rot and can the oil be tank mixed with Rovral or Vangard fungicides?
Yes and yes. Stylet-Oil has activity against Botrytis bunch rot. Extensive testing since 1993 has shown an excellent treatment for bunch rot to be a tank mix of Rovral at 1 lb/Acre + Stylet-Oil at 1% spray concen- tration. This tank mix is as effective as Rovral sprayed alone at the 2 lb/Acre rate. A similar performance boost occurs when Stylet-Oil is tank mixed with a label rate of Vangard or Elevate. NOTE: Using the oil at the 1% rate will control powdery mildew at the same time.
