Control Powdery Mildew and Black Mold in Fruiting Vegetables

July 7, 2020

This time of year, both powdery mildew and black mold can grow quickly and reduce the quality of fruiting vegetable crops. The rapidly expanding canopy provides an ideal environment for disease, largely because of additional moisture from irrigation and humidity. These factors create perfect conditions for both pathogens to begin infection.

According to the University of California IPM Program, black mold fungal spores only need 3 to 5 hours of moisture to germinate and begin infecting crops. You can see damage as soon as 4 to 5 days after heavy irrigation and high humidity. Meanwhile, powdery mildew appears gradually, as thin layers of mycelium appear on the plant, after heavy rainfall or irrigation. Both diseases can cause reduced yield potential, shortened production times and less flavorful yields. Early disease prevention is the best way to reduce the impacts of both black mold and powdery mildew.

Miravis® Prime fungicide, which recently received CA registration, has shown good crop safety in CA after years of trials and research. Miravis Prime contains 2 active ingredients, Adepidyn® technology and fludioxonil, each of which  offers a unique mode of action to control powdery mildew and black mold. Miravis Prime is the only FRAC 7+12 fungicide mixture in fruiting vegetables. With this unique mixture, it is an excellent rotation option in a market where triazoles (FRAC 3) and strobilurilins (FRAC 11) are relied upon heavily.
