Copper-based Fungicide
Description
Copper-based fungicide is a natural product made from copper that protects your plants from both fungal and bacterial diseases. When you spray it on your crops, it forms a protective layer or coating on the leaves and stems, like a shield. This shield prevents disease-causing fungi and bacteria from getting into your plants and making them sick. It works especially well against common problems like downy mildew (white or gray fuzzy growth on leaves), bacterial blight (dark spots and wilting), anthracnose (dark sunken spots on fruits and leaves), and leaf spots (brown or black spots on leaves). You can use it on vegetables like tomatoes, cucumbers, and peppers, as well as on fruit trees and field crops. The best way to use it is to spray before you see any disease symptoms - this is called preventive spraying. If you already see some disease starting, you can still use it, but you'll need to use a higher amount. It's very safe for the environment and is even approved for organic farming in many places. However, be careful when using it in very hot weather because it can sometimes burn the leaves. Also, don't mix it with alkaline products. Always wait 7 to 14 days after spraying before harvesting your crops.
