Problems solved by technology

Therefore, the pathogen is not easy to control
[0003] Chemical pesticides and fungicides are usually used to prevent and control ginkgo blight, and the problem of environmental pollution caused by the extensive use of chemical pesticides is becoming more and more serious
At the same time, the use of chemical pesticides and fungicides can cause various plant pathogenic bacteria to develop drug resistance and drug resistance, which increases the difficulty of control and even causes the failure of control.
In addition, chemical pesticides pose a threat to beneficial organisms because they are not selective
Moreover, many chemical pesticides are non-degradable or difficult to degrade, and are easy to accumulate in animals and plants, resulting in the enrichment of pollutants

Abstract

The invention provides a natural bactericide for controlling ginkgo blight. The natural bactericide is prepared by the following components: equisetum, cassia twig, herba cephalanoploris, caulis polygoni multiflori, coptis, asarum herb, duchesnea indica, fructus polygoni orientalis and composite multi-mineral. The natural bactericide for controlling ginkgo blight is abundant in raw material source and low in cost, is prepared by the pure natural components, has no toxicity and no pollutions, and is capable of effectively controlling ginkgo blight.

Description

technical field [0001] The invention belongs to the field of preventing and controlling diseases and insect pests, and in particular relates to a natural fungicide for preventing and treating ginkgo wilt and a preparation method thereof. Background technique [0002] Ginkgo blight is one of the main diseases of ginkgo, and it has been found in Hebei, Henan, Shaanxi, Shandong, Jiangsu, Zhejiang, Jiangxi, Guangxi and other provinces (autonomous regions). In addition to harming ginkgo, it also harms tree species such as chestnut. The disease occurs on the main trunk and branches. After being infected, the disease spots quickly surround the branches, often causing the death of the whole branch or the whole plant. After the pathogen of Ginkgo biloba blight invades the main trunk or branches from the wound, it produces discolored lesions on the smooth bark. The lesions are round or irregular, and the edges of the lesions are not obvious on the rough bark. Later, the lesion conti...
