When I first joined this site I was desperately looking for something to help my plants that had fusarium wilt.
This wilt fungus came from bags of soil from Lowe's.
All I found was this great natural product.
"MYCOSTOP
A biological fungicide developed from a naturally occurring biocontrol microbe
The organism was discovered by researchers at a leading European University and developed into a user friendly product by the biocontrol team at Verdera Oy in Finland . It is now an approved product in over 15 countries.
Key Highlights:
Control or suppression of many root rot and wilt pathogenic fungi. Pythium, Fusarium, Alternaria, Phomopsis, Rhizoctonia, Phytophthora, Botrytis. Plants often respond with increased vigor and yield, like a vitamin boost. Safe to apply. Organic approved. Non- phytotoxic. Use on all crops such as vegetables, herbs, ornamentals. Easy application. Small packets store for 1 yr. when refrigerated.
EPA registered since 1994. Increasingly used by large and
small growers.
Recent price reduction makes it very affordable.

Product Detail
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. Mycostop 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."
All natural and coupled with the fact that it benefits already healthy plants makes it a no brainer for me.
