Conquer Garden Fungus and Prevent Devastating Plant Disease
Safer Brand Garden Fungicide effectively controls a variety of damaging fungi and fungal infections that ruin the look and health of your precious plants. Fungi like powdery mildew, rust and black spot not only disfigure flowers, leaves and fruits, but when left uncontrolled they can cause plant diseases that completely overcome and kill vegetation. What’s more, fungi are infectious and easily spread to adjacent plants, so it’s very important to take control at the very first signs of fungus.
A Versatile Fungicide That’s Organic-Approved
This garden spray is OMRI-listed and compliant for use in organic gardening, which means you can apply it to plants, flowers and edibles without the damaging side effects otherwise caused by synthetic chemical fungicides. Use it up to the day of harvest to ensure your plants remain completely safe from spreading fungus.

A Simple Solution to Prevent Deep-Rooted Issues
Safer Brand Garden Fungicide uses the power of sulfur to stop the spread and growth of at least three types of harmful fungi, allowing your plants to continue to flourish. Fungi are living organisms that require specific environmental conditions, including a particular pH range, to live and advance. This carefully formulated solution of sulfur effectively changes the pH of plants to create an environment where fungus simply cannot thrive. Just apply Safer Brand Garden Fungicide at the first signs of powdery mildew, black spot or rust to prevent them from causing irreversible damage.

The Benefits of Organic Gardening
Besides preventing the harmful effects caused by synthetic chemicals, organic gardening offers a host of additional economic and health benefits. An organic regimen saves money in the long run by helping to create sustainable gardens that produce greater yields, reducing the need for fertilizers and pest controls over time. Furthermore, increased organic matter in your soil reduces erosion and conserves water, and organic produce is more flavorful and nutrient-dense. Because Safer products are third-party endorsed for use in organic gardening - both by OMRI and the USDA - you can be sure that you are using the healthiest and most economical solutions for you, your plants and your family.
