What is a fungicide? How many kinds are there? Please describe the use of certain doses or concentrations of chemicals called fungicides that can kill or inhibit the growth of some bacteria or fungi that cause plant diseases. There are two main principles of fungicides to control diseases: chemical protection and chemotherapy. Chemical protection is to spray fungicides before the disease occurs, to prevent the invasion of germs or to kill the bacteria to invade, so that the crops are protected. For example, spraying Bordeaux liquid on apple trees to control ring spot and anthracnose. Chemotherapy is the application of fungicides after crop disease to kill invaded bacteria or change the pathogenic process of bacteria, so as to achieve the purpose of reducing or eliminating the disease. For example, chlorothalonil has a good therapeutic effect on cucumber downy mildew and other diseases. According to the principle of fungicides to control diseases, fungicides are usually divided into three categories: protective fungicides, therapeutic fungicides and internal absorption fungicides.
