Buying Guide
- Spectrum of diseases covered: For tomato blight, prioritize products that explicitly list blight, leaf spot, and powdery mildew as covered diseases, or that provide broad-spectrum protection against fungal pathogens.
- Safety and suitability for edible gardens: If you grow edible crops, consider products marketed as safe for fruits and vegetables, with minimal harmful residues.
- Application method and timing: Ready-to-use sprays simplify application; apply early in the season or at first signs of disease for best results. Check label directions for frequency and coverage.
- Organic vs. conventional: Organic options may rely on biological or natural ingredients, while conventional products may use synthetic fungicides. Choose based on personal preference and crop needs.
- Impact on beneficials: Some products may impact beneficial insects; consider using targeted, site-specific applications and avoiding flowering plants when possible to protect pollinators.
- Resistance management: Rotate products with different active ingredients to reduce the risk of resistant fungal strains developing.
- Safety precautions: Follow PPE recommendations, especially for open containers or concentrates, and store products away from children and pets.
