When it comes to mancozeb, almost every farmer is very familiar with it. It is a protective fungicide developed in the 1960s. Due to its wide fungicide spectrum, good safety, resistance to rain erosion, low price and many other advantages, it quickly became the most popular protective fungicide among farmers and became the fungicide with the widest application range and the largest dosage. Today I will introduce to you an excellent fungicide that is better than mancozeb, with a wider fungicide spectrum, longer lasting effect, better safety, and more convenient use. It not only has a protective effect, but also has a therapeutic effect.
