Compatibility

The product can be used in tank mixtures with other herbicides based on glyphosate and acetochlor. In onion crops, depending on the weed infestation, a mixture with herbicides containing fluroxypyr or clopyralid is recommended to broaden the spectrum of weed control. However, in each specific case, a preliminary compatibility test of the tank mix components should be conducted. Do not mix with micronutrients, growth stimulators, adjuvants, or graminicides in tank mixtures.

Application features
