Walnut tree disease and insect pest comprehensive prevention method

Abstract

The invention discloses a walnut tree disease and insect pest comprehensive prevention method. The method comprises the steps of artificial prevention, physical prevention, physical trapping and control, and chemical administration. According to the method, the disease and insect pest prevention effect is improved, unified and effective prevention is conducted on walnuts in different growth stages, and requirements of modern walnut industrialize development are met. A pesticide is attached to a film in a film-forming mode, so that the use efficiency of the pesticide is improved, the consumption of the pesticide is reduced, the effective period of the pesticide is prolonged, the prevention effect is enhanced, and the pesticide is not easily damaged and lost due to environmental factors such as atmosphere, sunshine, rainwater and microorganisms; meanwhile, pollution of the pesticide to underground water can be effectively controlled, and the ecological environment change caused by the pollution can be prevented.

Description

technical field [0001] The invention relates to the technical field of pest management of walnut trees, in particular to a method for comprehensive prevention and control of pests of walnut trees. Background technique [0002] Walnut tree is a kind of arbor tree species, which belongs to Juglanaceae. It is a kind of woody oil family tree species with high comprehensive utilization value. It is also a kind of timber forest tree species for producing high-quality wood. and social multiple functions and benefits. Although the scale of planting has been relatively large in recent years, the planting quality has not been significantly improved due to the impact of diseases and insect pests. Therefore, it is of practical significance to study the control measures of walnut tree diseases and insect pests. [0003] The common diseases of walnut trees are: 1. Powdery mildew, which harms the young shoots and shoots of leaves, causes early defoliation, and even the death of seedlings...

[0005] The harm of pests and diseases seriously affects the normal development of walnuts, which reduces the yield of walnuts and affects the development of walnut industry

Over the years, various places have done a lot of work on the control of walnut disease and pests and accumulated rich experience, but the control of diseases and insect pests has not been standardized and integrated.

In addition, in the process of prevention and control, the application of pesticides mostly adopts simple spraying methods, and the use efficiency of pesticides is low, causing environmental pollution to the soil.
