Collis

Collis is a fungicide for the control of powdery mildew and rust diseases in a wide range of crops. The product contains two active ingredients from two different chemical groups with distinct modes of action, helping to delay the development of fungicide resistance. In areas where resistance to strobilurin fungicides has developed, Collis should not be applied more than twice per season and not in consecutive applications. Where resistance to both active ingredients in Collis has been confirmed, the product should not be used. To minimize the risk of resistance development, do not apply Collis more than three times per season in the same field, and avoid consecutive applications whenever possible. Collis provides the highest level of efficacy when used preventively for the control of powdery mildew.
