Problems solved by technology

Infectious pathogens are not easy to control
[0003] In the existing ginkgo seedling cultivation process, in order to prevent the infective pathogen of damping-off disease, chemical pesticide fungicides are usually used, and the environmental pollution problem caused by the large-scale 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 treating ginkgo nursery stock damping-off and a preparation method thereof. The natural bactericide is prepared from celosia seeds, rgy wormwood leaf, blackberry lily, pseudobulbus cremastrae seu pleiones, apocynum venetum, quispualis indica, schisandra chinensis, tree peony bark, dark plum and composite ore. The natural bactericide is prepared from the raw materials having wide sources, has a low cost, comprises pure natural components, is nontoxic and nuisanceless and can effectively prevent and treat ginkgo nursery stock damping-off.

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 controlling ginkgo seedling damping-off disease and a preparation method thereof. Background technique [0002] Ginkgo seedling damping-off disease is one of the main diseases of ginkgo seedlings, which commonly occurs in all ginkgo seedling cultivation areas. Seedling mortality is high, especially with late sowing. Ginkgo seedling damping-off disease occurs more often between April and June. Due to the different stages of the disease, there are usually four symptoms: ① Seed rot and seed buds are invaded by pathogens before they emerge, causing seed rot to be called bud rot type damping-off. ② stems and leaves rot. During the unearthed period of the young shoots, due to excessive humidity or too dense seedlings, etc., they are invaded by pathogens, causing the stems and leaves to stick and ro...
