Abstract

The invention discloses a method for preventing and treating fruit tree meloidogynosis by adopting a carboxymethyl chitosan protective film, and relates to a formula of a novel biological pesticide for preventing and treating fruit tree meloidogynosis and a preparation method of the novel biological pesticide. The preparation method comprises the steps of: preparing solution A in the weight ratio of water to citric acid to sodium hydroxide to chitosan oligosaccharide citrate of being 100: (8-12): (4-6): (0.5-2); preparing solution B in the weight ratio of water to potassium iodide to iodine to bioactive organic iodine of being 100: (0.3-0.8): (0.15-0.3): (0.01-0.02); preparing solution C in the weight ratio of water to carboxymethyl chitosan of being 100: (4-6); preparing solution D in the weight ratio of water to sodium alginate of being 100: (0.01-0.03); and finally, adding the solution B, the solution C and the solution D into the solution A in sequence. The novel biological pesticide can be used for effectively protecting wounds and promoting wound healing when the root systems of fruit trees have wounds because of grafting, meloidogynosis tumor removal and the like.

Description

(1) Technical field [0001] The invention relates to a formula for preventing and treating Agrobacterium tumefaciens in fruit trees by using a novel biological pesticide carboxymethyl chitosan protective film and a preparation method thereof. (2) Background technology [0002] Fruit tree root cancer (growngall of fruit trees), also known as crown gall, is a worldwide stubborn disease caused by Agrobacterium tumefaciens (Agrobactium spp.). This fungus has a wide range of hosts and can infect 643 species of plants belonging to 331 genera in 93 families, causing very large losses in production. Agrobacterium tumefaciens showed a negative Gram staining reaction and was suitable for growth in alkaline soils. The optimum pH value was PH7.3, and the range of acid and alkali resistance was PH5.7-9.2. It is recognized by the international academic community that all rhizobacteria use wounds as the only way of invasion, and they all use the same pathogenic mechanism to cause plant dis...
