Cymoxanil is a local systemic fungicide.It is effective to downy mildew and late(or early) blight on vegetables and fruit trees.When combined with other protective fungicides,e.g.,Mancozeb,other formulations which contain the element cuprum,and so on,it can effectively prevent and cure diseases mentioned above and the effect may keep longer.The recommended dosage to control grape downy mildew and potato late blight is 100-120gAI/ha.
Cymoxanil can decompose rapidly in crops,e.g.,the residues detected in grapes on the seventh day of the last application is only 0.1ppm after 8 times' application of 15g/100L dosage.Its half time in soil is shorter than two weeks.
