Actinovate SP Fungicide - 18oz - OMRI Listed

Streptomyces-Based Biological Fungicide for Fungal Disease Management, 18oz

Fungal pathogens like powdery mildew, Botrytis, and Pythium can spread through a greenhouse or growing operation faster than a grower can react to visible symptoms, and synthetic fungicide options aren't always compatible with organic production. Actinovate SP is a biological fungicide built on the beneficial bacterium Streptomyces lydicus WYEC 108, which competes with and suppresses a broad range of fungal pathogens on contact.

This 18oz package is OMRI Listed for organic use and can be applied as either a foliar spray or a soil drench, depending on whether the target pathogen affects foliage or the root zone.

What pathogens does Actinovate SP target

It's labeled for powdery mildew, Botrytis, Pythium, Rhizoctonia, Fusarium, Phytophthora, Verticillium, and other fungal pathogens. Coverage spans both foliar diseases and root-zone pathogens depending on application method.

Should I apply this as a spray or a drench

Use a foliar spray for foliage-affecting diseases like powdery mildew and Botrytis, and a soil drench for root-zone pathogens like Pythium and Rhizoctonia. Check the label for the specific rate and method matched to your target pathogen.
