SoilTech Permatrol is an OMRI listed natural fungicide based on botanical oils. This is a contact fungicide for use in an I.P.M. program for control of Powdery mildews and it is labeled for all crops.
Permatrol kills on contact by smothering Powdery mildew mycelium and preventing spore formation and dispersal. It causes immediate lysis, or destruction of fungus cells, including strains resistant to other classes of compounds.
A rate of 0.5% v/v spray solution is optimum for control of light to moderate infestations of Powdery mildew. A higher concentration up to 1.0% v/v may be necessary for heavy infestations of Powdery mildew.
