Problems solved by technology

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 curing nursery stock damping-off. The natural bactericide is composed of following components: mulberry leaves, tarragon, celandine, acalypha australis, coptis, buddhas lamp twigs and leaves, pogostemon, cirsium japonicum, aconitum kusnezoffii, and cordate houttuynia. The natural bactericide for preventing and curing nursery stock damping-off has the advantages of wide raw material resources and low cost, is composed of pure natural components, not only is non-toxic and non-harmful, but also can effectively prevent and cure the nursery stock damping-off.

Description

technical field [0001] The invention belongs to the field of preventing and controlling plant diseases and insect pests, in particular to a natural fungicide for preventing and controlling seedling damping-off disease and a preparation method thereof. Background technique [0002] Seedling damping-off disease, commonly known as "falling seedlings", "moldy roots", and "little foot plague", is the most common and serious disease in garden nurseries, mainly occurring in the seedling stage of forest trees and flowers. It is mainly caused by fungal infection of Pythium genus Flagellate subphylum. Pythium thorns and some species of Phytophthora can also cause disease. The host range of the pathogen is very wide, and in severe cases, it can cause dead seedlings in pieces. Seeds or young shoots are infested and rotted when they are not unearthed, and the disease occurs at the seedling stage. The stem base on the surface or under the surface presents water-soaked lesions, and the d...
