Medicament for preventing and treating apple tree ring spot and preparation method thereof

Abstract

The invention discloses a medicament for preventing and treating apple tree ring spot. The medicament is prepared from the following raw materials in parts by weight: 10-20 parts of a toxin degradingmixture, 1.5-6.5 parts of alternaria tenuissima protein, 1-5 parts of eugenol, 20-30 parts of nanosilicon dioxide, 3-6 parts of Zengkangling aqueous solution, 10-20 parts of a nano waterborne aqueousbinder, 20-30 parts of natural plant liquor, 3-5 parts of carbon enzyme and 3-6 parts of sodium para-nitrophenolate, wherein the toxin degrading mixture is obtained by mixing bacillus cereus, mucous membrane lactobacilli and beta-compound detoxifying enzyme in a mass ratio of 5:2:2. The medicament disclosed by the invention has the advantages that growth of pathogenic bacteria is inhibited from multiple aspects, drug resistance risk level of the pathogenic bacteria on a chemical agent can be lowered, the pathogenic bacteria can beneficially maintain sensitivity, drug resistance of the pathogenic bacteria on single dosage in the formula can be delayed, and sterilization effect is obvious; by adding a toxin degrading and adsorbing preparation, harm of toxin on crops can be obviously alleviated.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a medicament for preventing and treating apple tree ring disease and a preparation method thereof. Background technique [0002] Ring spot usually occurs when the fruit is near maturity and during storage. When the disease occurs, the lesion will form an oblate or oval reddish-brown disease on the fruit tree branches (trunk, main branch, side branch and twig) with the lenticels as the center. spot. In the second year of onset, many spores are produced in the center of the lesion, and the cracks between the lesion and the healthy part gradually deepen, and the diseased tissue is tilted like a saddle, and many lesions are often connected together, making the epidermis very rough. Many trees that have just entered the fruiting period are already covered with ringworm lesions. According to statistics, apple trees are high-incidence tree species of ring spot, which has caused huge economi...

Problems solved by technology

According to statistics, apple trees are high-incidence tree species of ring spot, which has caused huge economic losses to the apple industry.

[0003] At present, the commonly used prevention and control drugs in production are mainly chemical pesticides, the effect is not ideal, easy to produce drug resistance, high recurrence rate, high drug residues, serious environmental pollution
