Effect test

Embodiment 1

[0035] The biological source insecticide described in this example is prepared from the active ingredients of the following components: 25g of matrine, 12g of phyllotine, 8g of deervine, 15g of avermycin, 8g of pyrethrin and chitosan Sugar 2g. The above-mentioned effective ingredients can be mixed with auxiliary agents to prepare wettable powder. When used, 800-1000 times of wettable powder is used, which can effectively kill pests and prevent pests from infecting pathogenic bacteria.

Embodiment 2

[0037] The biological source insecticide described in this example is prepared from the active ingredients of the following components: 20 g of matrine, 10 g of picroderm, 5 g of deervine, 10 g of avermycin, 5 g of pyrethrin and shell Polysaccharide 1g. The other methods of preparation and use of this embodiment are the same as those of Example 1.

Embodiment 3

[0039] The biological source insecticide described in this example is prepared from the active ingredients of the following components: 30g of matrine, 15g of picroderm, 10g of deervine, 20g of avermycin, 10g of pyrethrin and chitosan Sugar 3g. The other methods of preparation and use of this embodiment are the same as those of Example 1.

Abstract

The invention provides a method for preventing and curing round spots of panax notoginseng. The method includes ecological soil treatment by applying Difulai and Woyiduo, agricultural preventing and curing; physical preventing and curing; biological control by applying a biological source pesticide containing effective components, amounts by weight, of 20-30 parts of matrine, 10-15 parts of celastrus angulatus, 5-10 parts of derris trifoliate, 10-20 parts of avilamycin, 5-10 parts of pyrethrin and 1-3 parts of chitosan; biological preventing and curing by spraying polyoxin water solution after seedling emergence and leaf expansion, and chemical preventing and curing by alternatively spraying wettable mancozeb powder and metalaxyl-mancozeb wettable powder during initial disease stage. Pathogens in soil can be suppressed and reduced through agricultural preventing and curing and physical preventing and curing measures, and the growth environment is turned to be unsuitable for growing pathogens. Pathogens are killed through biological preventing and curing and chemical preventing and curing means timely, and the biological source pesticide can prevent insects from spreading pathogens. Excellent effects for preventing and curing round spots of panax notoginseng are ensured.

Description

technical field [0001] The invention relates to a technique for preventing and controlling the diseases and insect pests of Panax notoginseng, in particular to a method for preventing and treating the round spot disease of Panax notoginseng. Background technique [0002] Panax notoginseng, also known as Tianqi, is a plant of Araliaceae of Umbelliferae, which has a wide range of applications in medicine. There are many diseases in the planting of Panax notoginseng, such as round spot, blight and so on. Among them, Panax notoginseng round spot is a devastating disease, and the loss caused by the round spot disease accounts for 30% to 40% of the whole growth process of Panax notoginseng. [0003] Symptoms of Panax notoginseng round spot disease are as follows: it can damage various parts of Panax notoginseng plants, and it occurs on Panax notoginseng plants of all ages. When the leaves are damaged, the pathogen generally invades through the stomata on the back of the leaves. ...
