Verdera Mycostop, 2 Grams

Additional Images


Developed 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 hastens roots development and increases the plants natural resistance to attack from disease.

Uses for Mycostop in RDWC include control of diseases caused by Pythium, Fusarium, Botrytis, Rhizoctonia and Phytophthora in CEA and greenhouse applications.

The most effective way to use Mycostop is preventatively, reapplying on a monthly basis. The Streptomyces griseoviridis bacteria survives in the root zone for several weeks protecting the crop against invading pathogens.

Apply Mycostop in your RDWC system preemptively or any time your plants suffer heat or chemical stress.
