Mode of action:
Kresoxim-methyl is a broad-spectrum fungicide. It controls ascomycete, basidiomycete, deuteromycete and oomycete fungi in a wide range of crops by preventing spore germination, mycelial growth and sporulation. Kresoxim-methyl has preventative and curative activity, but has little or no systemic activity.
Usage:
The fungicide will primarily be used as a foliar treatment and has particular activity against diseases of the leaf surface, such as powdery mildew (Erysiphe spp). It has a strong affinity for the waxy plant surface, adhering strongly under differing climatic conditions. The rate of penetration of the leaf cuticle is low. The fungicide diffuses laterally over the leaf surface after application, and provides translaminar control of disease on the untreated leaf surface. The fungicide has residual activity lasting 2-6 weeks, depending on crop and disease.
