Liquid Copper Fungicide is a residential-use fungicide containing 27.15% copper diammonia diacetate. It is designed for the control of various bacterial and fungal diseases on vegetables, ornamentals, and fruit crops. The product works by providing a protective layer on plant surfaces. It can be used on a wide variety of plants including apples, avocados, citrus, grapes, mangoes, peaches, and more, as well as various vegetables like beans, cucumbers, and tomatoes. Application involves mixing the liquid concentrate with water and applying it via a sprayer. Note that this product can stain metal surfaces and should not be used on certain plants like melons or certain citrus varieties during specific growth stages. It is important to follow specific dilution rates based on the target crop and disease to avoid phytotoxicity. Always observe weather conditions, as application should be avoided if rain is expected shortly after treatment.
