Buying Guide
- Formulation and application: Choose ready-to-use sprays for quick treatments or concentrates when you need larger-scale coverage or volume control. Consider the ease of mixing and compatibility with your spraying equipment.
- Active ingredients and mode of action: Systemic fungicides (e.g., propiconazole) provide internal protection but may require more careful rotation to avoid resistance. Contact fungicides act on the surface and can be effective when combined with other controls.
- Organic and safety considerations: If you prefer organic gardening, look for OMRI-listed products or those labeled safe for use around kids and pets. Citric acid-based options offer milder formulations with fewer residues.
- Scope of diseases: Match products to target pathogens (powdery mildew, rust, leaf spots, blight, Botrytis, etc.). Some products also address insect pests, which can be beneficial for integrated pest management.
- Environmental impact: Evaluate whether the product uses copper-free chemistry, peroxyacetic acids, or other materials that minimize soil and water contamination.
- Label instructions and safety: Always follow label directions for dilution, spray intervals, and pre-harvest intervals. Safety gear and storage considerations should be reviewed before use.
- Plant and landscape context: For turf, ornamentals, and edible gardens, ensure the product is labeled for the target plant types and check compatibility with beneficial organisms when applicable.
- Resistance management: Rotate products with different modes of action to reduce the risk of pathogen resistance and extend the efficacy of your fungicides over time.
