Actinovate biological fungicides offer growers and home gardeners a very powerful and versatile Organic (OMRI Listed) tool to control fungal pathogens. Actinovate works just like other biological controls (the classic example of a biological control is the use of ladybugs to control aphids), only the organisms in Actinovate act on a microscopic level. Actinovate uses a natural enemy of fungal pathogens to keep these pathogens from destroying your crops. This natural enemy is a beneficial bacteria called Streptomyces lydicus WYEC 108, which is a naturally occurring soil bacterium that was originally isolated from the roots of a linseed plant in England, and patented worldwide.
