Verdera Mycostop

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 produce plant root stimulating hormones which hasten root development and increase the plant's 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 preventative, reapplying on a monthly basis. The Streptomyces griseoviridis bacteria survive 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.
