DIPLOMAT BIOFUNGICIDE
Diplomat is a biological fungicide derived from the natural fermentation of the soil bacterium Streptomyces cacaoi. Classified as a FRAC Group 19 fungicide, it works by inhibiting chitin synthesis, an essential component of fungal cell walls. Without chitin, susceptible fungi cannot grow, infect plant tissue, or spread within the crop. Diplomat is particularly effective against diseases such as powdery mildew, Botrytis, Monilinia, Anthracnose, and other fungal pathogens affecting fruit, vegetable crops, and ornamentals.
Key features and benefits of Diplomat include its unique mode of action, low resistance risk, suitability for integrated pest management (IPM) and organic production systems. As the only fungicide in FRAC Group 19, it provides an excellent rotational partner for resistance management programs and helps reduce cross-resistance concerns. The product offers strong preventative disease control, is safe on most crops, and generally has minimal impact on beneficial insects and natural enemies. Because it is derived from natural sources and has a favorable environmental profile, Diplomat is a valuable tool for growers seeking effective disease management while supporting sustainable crop production practices.
