Background Of Fungicide Production

According to surveys, there are more than 80,000 pathogenic microorganisms (fungi, strong bacteria, rickettsia, mycoplasma, viruses, algae, etc.) that are harmful to plants worldwide. Plant diseases cause huge losses to agriculture, and the average annual reduction in crop production worldwide is about 500Mt. In history, there have been many disasters in which a certain plant disease epidemic caused severe famine and even a large number of people starved to death. The use of fungicides is an economical and effective method to prevent and control plant diseases.
