Kocide 3000-O is a dry flowable fungicide/bactericide containing 46.1% Copper Hydroxide (equivalent to 30% metallic copper). It is used to control a wide variety of bacterial and fungal diseases across diverse crops, including citrus, field crops (like corn, soybean, and sugar beet), small fruits (such as berries and grapes), and tree crops (including almonds, apples, and avocados). The product is applied via spray, granular, or concentrate methods. It is highly effective for managing diseases like citrus canker, bacterial leaf spot, and various blights. When handling, technicians must wear long-sleeved shirts, long pants, and closed-toed shoes. If using specialized equipment like sprayers, ensure they are properly cleaned and maintained to avoid contamination. Note that the product can be reactive on certain metals like galvanized roofing. Always follow specific application rates and timing instructions provided in the crop classification tables to ensure efficacy and prevent plant injury.
