Problems solved by technology

[0003] In the existing ginkgo seedling cultivation process, chemical pesticides and fungicides are usually used to prevent stem rot, and the environmental pollution caused by the extensive use of chemical pesticides is becoming more and more serious
At the same time, when chemical pesticides and fungicides are used, various plant pathogenic bacteria will develop drug resistance and drug resistance, which will increase the difficulty of control and even cause control failure
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 preventing and controlling ginkgo seedling stem rot. The natural bactericide is prepared from the following components: radix bupleuri, folium artemisiae argyi, blackberry lily, areca-nut, coptis chinensis, quispualis indica, mint, moutan bark, houttuynia cordata and myrobalan. The natural bactericide for preventing and treating ginkgo seedling stem rot is abundant in raw material source, low in cost, non-toxic and pollution-free, and is prepared from pure natural components; moreover, the ginkgo seedling stem rot can be effectively prevented and controlled.

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 stem rot of ginkgo seedlings and a preparation method thereof. Background technique [0002] Stem rot of ginkgo seedlings is one of the main diseases of ginkgo seedlings. It occurs commonly in all ginkgo nursery areas. It mostly occurs in 1-2 year old ginkgo seedlings, especially in annual seedlings, which often causes a large number of seedlings to die. The stem rot of ginkgo seedlings turns brown at the base of the seedlings in the early stage of the disease, and the leaves lose their normal green color and droop slightly, but do not fall off. The susceptible part rapidly expands upwards, so that the whole plant dies. The cortex at the base of the diseased seedlings shrunk, and the tissue in the skin rotted into spongy or powdery grayish white with many tiny black sclerotias. The pa...
