Developed from a naturally occurring bacteria, Streptomyces griseoviridis, Mycostop Biological Fungicide thrives in the root zone of plants. When applied as a drench or spray the dried spores and mycelium of the Streptomyces culture in Mycostop germinate and begin to grow on and around the plant roots. In doing so they create a biological defense against root infecting pathogenic fungi which cause disease such as wilt and root rot.
Mycostop is used by growers for diseases caused by pythium, fusarium, botrytis, alternaria, phomopsis, and to a lesser extent for rhizoctonia and phytophthora. It has particularly good activity against fusarium.
Mycostop has been shown to increase plant vigor and yields even in the absence of obvious root pathogen activity. The explanation is that the Streptomyces produce plant root stimulating hormones (which has been demonstrated in the lab) or the Streptomyces control minor root pathogens which slowly feed on and damage roots.
