Problems solved by technology

The measures usually adopted in the diseased area are: soil disinfection with chemical fungicides, spraying above ground, dripping at the base or smearing of lesions, but no matter what kind of chemical agents can not effectively control canker disease, it often shows that the control effect is not good, and the treatment is not good. Thorough problems; or by strengthening forest management, changing chemical fertilizers to ordinary farmyard manure, plant ash, biogas slurry; or wrapping plastic films on susceptible tree trunks

Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The present invention is tested as follows in the walnut planting area of ​​Yunti She Nationality Township, Ningguo City:

[0037] progress status

[0038] 1. The situation of the test site

[0039] The experimental site was selected in the forest area of ​​Wangshengfa Fruit Farmer in Bailu Village, Yunti She Nationality Township, Ningguo City. The average age of the walnut trees in this area is 20-30 years, and more than 70% of the walnut trees have had their main stems cut off due to severe canker. The incidence of canker in the test area was 100% in the previous year, and the degree of occurrence was serious. T...

Abstract

The invention relates to a fruit tree weak parasitic disease green prevention and control method which includes the steps: improving soil environments by bio-organic fertilizers and mineral ecologicalfertilizers, and spraying induced immune activators to activate disease-resistant mechanisms of plants; spraying plant source sterilizing agents in an auxiliary manner before weak parasitic diseaseshappen. According to the method, improvement of soil, induced immune activation and the plant source sterilizing agents are combined, immunity and disease resistance of walnuts are improved, canker ofthe walnuts is effectively controlled, production capability of fruit trees is improved, a fruit bearing period is prolonged, and the method is of great significance for guarantee of production benefits of walnut framers and facilitating of development of rural economy walnut industry.

Description

technical field [0001] The invention relates to the technical field of green plant protection, in particular to a green prevention and control method for weak parasitic diseases of fruit trees. Background technique [0002] There are many saprophytic parasites in nature, such as: Botrytis, Valsa, Botryos-phaeria, Rhizoctonia, Fusarium Fusarium, Verlicllium, Armillariella, and Penicillium that cause fruit rot are a class of non-obligate parasites with very weak parasitism. They usually damage the non-green parts of plants, such as roots, branches, flowers and fruits, etc.; or only damage the green parts of plants when the plants are in a severely weakened state, such as Alternaria. Without specific environmental conditions, they cannot parasitize living organisms. Such weak parasites are also called facultative parasites. Diseases caused by weak parasitic pathogens are called weak parasitic diseases. Weak parasitic pathogens usually have a wide host range, no obvious physi...
