Fungicides

Fungicides

When fungal disease strikes, it advances quickly, and an untreated crop can escalate from a few spots to significant loss within days. Growers rely on fungicides to stay ahead of these threats. Tractor Supply provides options for fields, orchards and home gardens of any size. As part of our broader line of agricultural (AG) chemicals designed to protect plants, lawns and gardens, fungicides are available in both organic and conventional forms.

Defend Plants Against Fungal Threats

Fungal pathogens attack all kinds of crops, showing up as rust, mildew, blight or leaf spot, and a helpful product either kills the fungus or holds it back. Different from insecticides, which target insects, fungicides target organisms that invade roots, stems, leaves and fruit. A few stop spores before they can germinate. Others take on an infection that is already underway and helps to keep it isolated to the affected area. Organic choices lean on copper, sulfur or biological agents, while conventional synthetics are built for tougher disease pressure. The right choice depends on what you grow, what you are fighting and where you sit in the season.

Liquids, Granules and Powders

Concentrated fungicides are mixed with water and fed into a sprayer, which is required for large fields. For a single plant or a problem corner, a ready-to-use spray gets it done. Granules scatter over the soil, work down to the roots and release on a slow schedule. Dusts stay dry and grip the leaf for quick coverage on small plots, and powders, despite the name, usually go into solution and spray out similar to a concentrate. Because the active ingredient shifts from form to form, the protection you get lines up with your equipment and your acreage.

Surface and Internal Protection

A fungicide guards a plant in one of two ways. Contact fungicides remain on the plant’s surface, forming a protective shield that prevents spores from germinating. Systemic types are absorbed into the tissue, then move through the plant and work on the infection from the inside out. Contact fungicides typically provide even coverage across exposed surfaces, whereas systemic fungicides penetrate areas a spray might miss and remain effective after rainfall.
