It has a protective action, activating the plant's defense mechanisms. It is accepted by agroecology as an alternative product when used within the appropriate copper levels. Deficiency symptoms appear on the youngest leaves. The leaves initially acquire a dark green hue. Often, deficient leaves are deformed, crooked, and grow on scion branches, such as citrus trees. These scion branches are curved in an "S" shape. Plants treated with copper solutions rarely present copper deficiency. PREVENTIVE DISEASE CONTROL: Ferti-Protector 1. BORDEAUX MIX It has fungicidal and bacteriostatic effects when applied preventively and can also act as a repellent for many insects, such as leaf miners. Bordeaux mixture is an alternative pesticide prepared with a mixture of copper sulfate and hydrated quicklime. Each crop has a specific dosage. The classic formula is 0.5% in the seedling stage (500 grams of copper sulfate + 500 grams of quicklime and 100 liters of water) and 1.0% in the adult stage (1.0 kg of copper sulfate + 1.0 kg of quicklime + 100 liters of water). Apply with a high-pressure sprayer (100 pounds), covering the entire plant with micro-droplets. Apply in cool, windless weather. ALTERNATIVE CONTROLS RICE CULTURE: Many irrigated rice producers have reduced snail infestations by adding small amounts of copper sulfate to the water when the crop begins to flood. COMBATTING SAUVAS: An alternative method being used is to place small doses of copper sulfate in the openings of leaf-cutter ant burrows. With rain or irrigation, the product is carried deep into the snail nest, eliminating the fungi that the ants feed on.
