MYCOSTOP main image


A natural way to combat root disease in your crops

MYCOSTOP® contains a high concentration of Streptomyces K61, a soil Actinobacteria that is naturally found in peat moss and that was isolated by researchers at Lallemand Plant Care due to its fungicidal properties. It effectively prevents the development of a complex of root fungus that causes damping off and dieback in agricultural and horticultural crops ( Fusarium, Pythium and Phytophthora).
