Frequently Asked Questions

What diseases does Fosphite control?

It's labeled to control Phytophthora, Pythium, and Downy Mildew on food crops, turf, and ornamentals, with additional label coverage for Phytophthora in conifers and Pythium specifically in turf. That range makes it a broad systemic option against common water-mold pathogens.

Is Fosphite an EPA Reduced Risk Pesticide?

Yes, JH Biotech's own product documentation confirms Fosphite carries the EPA's 'Reduced Risk Pesticide' designation under registration number 68573-2, and it's registered for use in all 50 states plus Washington, D.C. That designation reflects a lower environmental and toxicological risk profile relative to conventional fungicide alternatives.

How does a systemic fungicide differ from a contact fungicide?

A systemic fungicide like Fosphite moves through the plant's own tissue after application, providing protection beyond just the treated surface, while a contact fungicide only protects where it's directly applied. That systemic movement is part of why Fosphite is also described as having a growth-promoting function alongside disease control.

What crops is Fosphite approved for?

Beyond food crops, turf, and ornamentals on the core label, Fosphite carries additional FIFRA 2(ee) recommendations covering citrus, grapes, and tree/nut crops. Always confirm current label directions for the specific crop and application method before use.
