The fungicide is divided into a protective, contact fungicide and a systemic fungicide. Protective, contact-killing fungicides can kill or prevent the invasion of pathogens before they invade plants. They are protected from damage by using plants. These fungicides do not enter the plant and only deposit on the surface of the crop to protect them. The disease prevention spectrum is wide, the control effect is stable, and it is not easy to induce the resistance of the bacteria. Systemic fungicides have systemic activity, have direct toxic effects on pathogens, inhibit or affect pathogenic processes; or affect plant metabolism, so that plant response to pathogens can be alleviated or prevented from occurring, such fungicides are planted After absorption, it runs in plants, killing invading pathogens, and easily attracting the resistance of pathogens.
