Lentinan is a broad-spectrum biological agent for the treatment of plant viral diseases

Lentinan is a kind of sugar protein complex composed of linear molecules with special structure, which can strongly kill crop viruses. It can react to virus infection and cell damage to enhance the accumulation in their cell wall, participate in plant disease resistance and defense response, synthesize polypeptides in plant cytoplasm, and then secrete them into cell space through plasma membrane channel. After various factors, it can be deposited on different cells of vascular bundle, so that this product has strong resistance to infection and expansion of various pathogens, Repair cell damage. While synthesizing polypeptides in plant cells, the product can parasitize in plant cells for a long time to form a protein sustained-release agent. At the same time, this product is rich in a variety of amino acids, which can prevent and resist viruses . Lentinan is a broad-spectrum biological agent for the treatment of plant virus diseases. It is an efficient biological pesticide for the treatment of virus diseases extracted from mushroom culture medium to inhibit the replication of virus disease RNA. It has good wettability and permeability on the plant surface, can be quickly absorbed and degraded by plants, and is safe for people, livestock and the environment. It is suitable for green pollution-free bases. Lentinan directly inactivates TMV virus particles in vitro, making them lose their infection ability, but this passivation effect is reversible; Inhibit the proliferation of viral RNA in plants, reduce the number of viral RNA, inhibit the replication of viral RNA and protein synthesis, so as to control the virus. Lentinan can induce plants to produce resistance factors to virus, enhance the disease resistance of crops, and will not relapse after cure; It can promote the synthesis of plant protein, make crops more robust and significantly enhance disease resistance. Lentinan also has disease resistance and antibacterial activities, and can induce plants to produce and accumulate disease resistant substances such as salicylic acid, phytoalexin and chitinase. Previous studies have shown that lentinan can not only induce crops to produce good induced resistance to viruses, but also inhibit plant pathogens, promote crop seed germination and growth, and improve crop stress resistance. It can be widely used to control virus diseases of rice, tomato, pepper, cucumber, tobacco, potato, flowers and other crops.

Lentinan is an efficient agricultural fungicide. It not only has a good inhibitory effect on crop viral diseases, but also has a certain preventive effect on crop fungal and bacterial diseases. It can significantly improve crop immunity, improve crop yield and crop quality, and is conducive to the production of green pollution-free food. It can be widely used in wheat, corn, rice, peanut, soybean, tomato, pepper, cucumber, tobacco, citrus, jujube, apple, pear, peach and other crops.

Functional characteristics of lentinan:

Inhibit virus spread in plants: Reduce the number of viruses and induce plants to produce resistance factors.

Stimulate the immune system of crops
