Problems solved by technology

The number of plant viruses is large, the damage is wide, the economic loss is large, and it is difficult to prevent and control. At present, the effectiveness of the agents used to prevent and control viral diseases in production is generally 30%-60%. It is difficult to effectively control the harm of viral diseases. New agents are needed

Abstract

The invention discloses a composition for preventing and treating plant nematode and virus diseases, and an application of the composition, belonging to the technical field of biopesticide. The composition takes chitosan oligosaccharide and lentinan as active ingredients and can be made into liquid or effervescent tablets. The composition can be used for separately and simultaneously preventing and treating the plant nematode and the virus diseases of plants, and has good using effect on pumpkins, winter squashes, pepper, alfalfa, lily, strawberries and gingers, thus effectively reducing the crop diseases and pest and improving the yield and the quality of crops.

Description

technical field [0001] The invention belongs to the technical field of biological pesticides, and in particular relates to a composition for preventing and treating plant nematodes and viral diseases and its application. Background technique [0002] Root-knot nematodes (Meloidogyne spp.) are a class of plant pathogens that parasitize the roots of crops and seriously endanger the world's agricultural production. There are more than 3000 species of host plants. Diseases can cause crop yield reduction of 10%-20%, and can reach more than 75% in severe cases. The damage to plants is second only to fungal diseases, causing about US$100 billion in losses every year. Nematodes not only directly harm host plants, but also transmit bacteria and viruses. Chemical control plays an important role in the control of root-knot nematodes, but most of the chemical nematicides currently used are single or compound preparations of organophosphorus or carbamates, and most of them are highly ...
