Abstract

The invention discloses a plant immunity resistance inducer prepared by using shrimp and crab shells and a preparation method thereof. The plant immunity resistance inducer comprises, by weight, 3-8 parts of modified chitin, 0.5-1 part of traditional Chinese medicine extracts, 0.1-0.5 part of phosphate, 0.1-0.5 part of organic acid and 50-150 parts of water. The preparation method comprises the steps of mixing the modified chitin, the traditional Chinese medicine extracts, the phosphate, the organic acid and the water to homogeneity based on the weight ratio, conducting spray drying on the mixed solution, and collecting the dry material which is the plant immunity resistance inducer. The the chitin originating from the shrimp and crab shells is subjected to structural modification to produce a modified chitin with long distance signal conducting capability and high resistance to inducing plants. The plant immunity resistance inducer using the chitin as the main material possesses a positive immunity effect to the infection of multiple pathogens, particularly to the root rot fungus and phytophthora of tomatoes, and the disease incidence rate is lower than 5%.

Description

technical field [0001] The invention belongs to the technical field of biological pesticides, and in particular relates to a plant immune inducer prepared by utilizing shrimp and crab shells and a preparation method thereof. Background technique [0002] Plant immune inducers, also called plant vaccines, are a new type of biological pesticides, which have significant effects on disease prevention, antifreeze, production increase, and quality improvement. They are harmless to humans and animals, and do not pollute the environment. It is a new field of vaccine engineering technology after human vaccines and animal vaccines, and it is also a relatively popular research direction for the creation of biopesticides in the world. [0003] Plant immune inducers have no direct killing effect on crop diseases and insect pests, but are induced or activated by exogenous organisms or molecules to produce resistance to certain pathogens or inhibit the growth of pathogens. When it is appl...
