Liqui-Cop Copper Fungicide is formulated to prevent a broad spectrum of plant diseases, including anthracnose, brown rot, blight, downy mildew and leaf spots. It offers complete protection when used across fruit trees, nut crops, and ornamentals. The gel formulation helps it adhere and remains rain-fast after drying, providing longer-lasting coverage and reducing wash-off during wet conditions.

This gallon-size copper fungicide provides durable disease control for citrus and other fruit and nut trees. It is designed for protective use across a broad range of plant diseases and is suitable for outdoor fruiting trees and containers.

It complements pest management by promoting robust tree health and better fruit quality.
Farmer’s Secret Citrus Tree Booster Fertilizer (8 oz)
Farmer’s Secret Citrus Tree Booster is a super-concentrated plant food designed for all citrus trees. It recommends diluting one teaspoon per gallon of water and applying weekly along the drip line. For first-season trees, light weekly feeds are advised, while mature trees may use up to two teaspoons per week. This product supports vigorous growth and abundant fruit production as part of a broader tree-care strategy.
Farmer’s Secret Citrus Tree Booster (32 oz)
This larger bottle provides a cost-effective option for households with multiple citrus trees or larger specimen trees.

Buying Guide: Key Considerations For Citrus Tree Pesticide And Care Purchases
- Target pests and diseases: Identify the primary threats in your region—aphids, scale, whiteflies, fungal diseases like blight or powdery mildew—and choose products that address those issues specifically.
- Mode of action and timing: Consider whether you prefer contact sprays, systemic treatments, or copper-based fungicides. Plan applications around planting cycles, fruit set, and seasonal weather patterns to maximize effectiveness and minimize risk to pollinators.
- Compatibility with fertilizer: If you use soil amendments or organic fertilizers, ensure the pesticide product is compatible and won’t impede nutrient uptake or soil biology. Some organic options may be gentler on beneficial insects when applied correctly.
- Container vs. field trees: For potted citrus, select products suitable for container-grown plants and follow label directions for smaller root systems and potential drift concerns.
- Environmental considerations: Copper-based fungicides can accumulate in soil; use sparingly and rotate with other modes of disease control to prevent buildup and resistance.
- Safety and application: Always wear recommended protective gear, apply during appropriate weather (avoiding rain immediately after application), and follow dilution instructions to minimize phytotoxicity and runoff.
- Regulatory and label compliance: Confirm product labels are current and compatible with edible crops. Some products may have specific restrictions on harvest intervals or use near fruiting trees.
- Integrated approach: Combine resistant varieties, proper pruning, sanitation, and timely feeding along with targeted pesticides to create a holistic citrus-care plan.
- Longevity and coverage: For longer protection, consider products with rain-fast properties or longer residual control, especially in humid climates where disease and pest pressure remains high.
- Cost and availability: Compare per-area coverage and concentrate vs. ready-to-use formats to match your budget and garden size while avoiding waste.
