Product Overview

Howler Lawn and Garden Fungicide is organic, specially formulated to provide a preventive and long-lasting activity of soilborne and foliar diseases. This revolutionary fungicide features multiple modes of action which work by producing natural antibiotics and enzymes that directly attack pathogens and break down the cell walls of fungi to keep the spores from attaching to leaves. It uses a new technology based on the plant microbiome, along with a proprietary platform which identifies and catches isolated microbials that help fight and suppress disease and pests. It is guaranteed to provide effective and broad-spectrum control of fungal diseases like anthracnose, brown patch, fusarium patch, pythium blight, pythium root rot, and pythium crown rot. It also has minimal pre-harvest and re-entry intervals.  Howler Lawn and Garden Fungicide is OMRI certified.

    Great for vegetable garden

    By Matt on 06/12/2020

    Super easy to use--just mixed in a spray bottle and applied to home vegetable garden. I've seen a big improvement in my melons and cucumbers---where I was seeing a lot of brown and wilting leaves, since applying Howler all the new growth has been really clean and healthy. Highly recommended!

Is this safe for pets -- no mention on label, just a warning ": Harmful if inhaled, absorbed through the ski..

Label does not give pet safety information. What if dog eats grass after treatment? What if he walks on treated lawn while wet? Heck, what about kids????


Howler Lawn and Garden Fungicide is safe if used as directed. Keep people and pets out of the treating area until the product has fully dried.
