A bactericide is a compound that has a toxic effect on pathogenic microorganisms. It can sterilize fungicides killed by pathogenic microorganisms, and can also inhibit the bacteriostatic action of pathogen spore germination or growth, and achieve disease prevention. And the purpose of treatment.
The action of the Bactericides is different, and the method of use is also different. There are two ways of action of the fungicide, one is a protective fungicide, and the other is a systemic fungicide. The protective fungicide directly contacts the pathogenic bacteria in vitro or on the surface of the plant, killing or inhibiting the pathogenic bacteria, making it unable to enter the plant, thereby protecting the plant from the pathogen.
The systemic fungicide is applied to a part of the crop body and can be absorbed by the crop and transported to other parts of the crop body for action. The systemic fungicide has two kinds of conduction modes. One is the apical conduction, that is, the drug is absorbed into the plant body and then transmitted to the top of the plant, the top bud, the leaf and the leaf edge with the transpiration flow. The current systemic fungicide carbendazim fungicide is mostly of this type. The other is conduction to the base, that is, the drug is absorbed by the plant body and then transmitted downward along the transport of the photosynthesis product in the phloem.
