Problems solved by technology

However, the active ingredient of this patent is volatile oil, which is not suitable for maintaining the drug effect for a long time, and is easy to volatilize
[0004] Chinese patent CN102812972A discloses a botanical pesticide, especially relates to a plant extract combination and preparation method for preventing and treating apple tree rot, which solves the problems of single raw materials and unsatisfactory effects of existing drugs for preventing and treating apple tree rot. Composed of 0.5-1.5 parts of Sophora japonica whole plant, 1-3 parts of Sophora flavescens fruit, 0.5-1.5 part of Toosendan fruit, 0.3-0.7 part of Euphorbia chamaeba root, 0.2-0.4 part of tobacco leaf
However, the raw materials of the above-mentioned patents are mainly fruits, and the extraction rate of active ingredients is low.

Abstract

The invention belongs to the technical field of pesticides, and particularly relates to a biological bactericide for preventing and treating apple tree canker and a preparation method thereof. The biological bactericide for preventing and treating apple tree canker is prepared from the following raw materials in parts by weight: 5-10 parts of anemone, 8-12 parts of Mangnolia officinalis, 7-15 parts of Xanthium strumarium, 8-15 parts of rhizoma anemarrhenae, 10-20 parts of mulberry bark, 5-10 parts of fructus cnidii, 4-8 parts of Chinaberry seed, 10-20 parts of dispersing agent, 3-10 parts of wetting agent, 0-5 parts of disintegrant and 40-60 parts of filler. The biological bactericide for preventing and treating apple tree canker has the advantages of stable drug properties, long preservation period (up to 2 years), no residue, high degradability and no harm to the human and livestock, and can be popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a biological fungicide for preventing and treating apple tree rot and a preparation method thereof. Background technique [0002] Apple tree rot disease, also known as rotten skin disease and stinky skin disease, is a common and serious disease in major apple producing areas in my country. Apple tree rot disease generally occurs on the trunk, main branches and pruning openings of apple trees. When the disease occurs lightly, it will cause the rot of the apple bark, weaken the tree vigor, and reduce the yield and quality of apples. Withered, the whole tree died, and even caused the garden to be destroyed. The wide application of traditional chemical pesticides not only brings economic benefits to people, but also brings a series of negative effects, such as pollution and residue problems of chemical pesticides. Due to the low toxicity, high selectivity and easy deg...
