Disease-preventing and insect-preventing composition as well as preparation method and application thereof

Abstract

The invention provides a disease-preventing and insect-preventing composition as well as a preparation method and application thereof. The composition is prepared from the following raw materials in parts by weight: 1 to 3 parts of trichoderma harzianum bacterial liquid, 2 to 4 parts of beauveria bassiana bacterial liquid, 2 to 4 parts of metarhizium anisopliae bacterial liquid, 3 to 7 parts of bacillus thuringiensis bacterial liquid, 1 to 3 parts of morchella esculenta bacterial liquid, 0.3 to 2 parts of agilawood spiral alcohol, 0.1 to 0.5 part of amino-oligosaccharin, 0.2 to 0.9 part of salicylic acid, 0.1 to 0.9 part of dextran, 1 to 3 parts of apiane, 1 to 5 parts of limonene amine and 2 to 6 parts of beta-amyrin. The composition is based on scientific proportioning of all the raw materials, so that the activity and the insecticidal effect of the composition have a remarkable synergistic effect. The composition has a remarkable killing effect in the aspect of preventing and treating insect pests of crops, and especially has the best effect on stem borers, aphids and thrips. The composition can also be used for preventing and treating various crop pathogenic bacteria, especially powdery mildew, downy mildew, gray mold, rice blast, late blight and anthracnose.

Description

technical field [0001] The invention relates to the technical field of agricultural disease prevention and insect prevention, in particular to a composition for disease prevention and insect prevention, its preparation method and application. Background technique [0002] With the increasing calls for environmental protection, the negative impact of the extensive use of highly toxic pesticides on agricultural production and the ecological environment has attracted worldwide attention. In order to protect the environment in which humans live and the sustainable development of agriculture, the development and use of pesticides Will be strictly subject to environmental and ecological constraints. In the cultivation process of crops, diseases and insect pests cannot be avoided, and the current disease-resistant and insecticidal compositions have poor disease prevention and insecticidal effects, especially broad-spectrum insecticides, although they can kill various diseases and i...

AI Technical Summary

Problems solved by technology

In the cultivation process of crops, diseases and insect pests cannot be avoided, and the current disease-resistant and insecticidal compositions have poor disease prevention and insecticidal effects, especially broad-spectrum insecticides, although they can kill various diseases and insect pests. , but the control effect is not good, the patent "an insecticide composition and insecticide and its application" application number: 201310129581.4, in which the control effect on cabbage aphids is better, but the control effect on litchi aphids is biased. The control of rice borer is acceptable, but the control effect on mango tree borer is not good; the control effect on rice thrips is up to 78.93%, but the control effect on rubber thrips is slightly worse

The patent "a fungicidal composition", application number: 201810465970.7, compared with the control effect of one-time spraying, the control effect on cucumber powdery mildew, pepper anthracnose, and cucumber downy mildew is better, but the effect on jackfruit, lotus Fog, lemon, rice, betel nut, and durian have poor control effects on the surface of leaves; therefore, it is necessary to study a high-efficiency fungicidal composition to solve the problem of preventing crops from pests and diseases
