Verdera Mycostop, 25 gDeveloped from a naturally occurring bacteria, Streptomyces griseoviridis, Mycostop thrives in the root zone of plants. In doing so it creates a biological defense against root infecting pathogenic fungi which cause disease such as wilt and root rot. Mycostop has been shown (in independent trials) to increase plant vigor and yields even in the absence of obvious root pathogen activity. The active bacteria produces plant root stimulating hormones which
