Questions to ask

To confirm phytotoxicity, we suggest you ask yourself at least the following questions:

• Was the previous crop weeded with residual herbicides ?
• Have herbicide treatments been carried out near your crop ?
• Did you rinse your treatment equipment wel ?
• Do you take good care of your spraying equipment (cleaning, calibration) ?
• Did you use the right product, at the right dose ?
• Did you follow the recommendations for use indicated on the packaging ?
• Have you mixed incompatible products or too many products together ?
• Did the applications take place under good conditions, particularly wind and temperature ?
• Has manure with straw been brought into the crop ?
• Are you sure of the quality of the irrigation water, could it not have been polluted by a herbicide in particular ?
