Mixing formulations of diazinon or Danitol with Captan or Captec have caused crop injury in the past. Therefore, diazinon and Captan formulations should not be tank-mixed. This type of phytotoxicity results from either a direct interaction of the active ingredients or an interaction of the “inert” ingredients in one formulation that enhances the toxicity of the other one.
