Embodiment 1

[0097] Example 1: Preparation of 30% wood tar Boluohui alkaloid smear

[0098] At room temperature, take 30 parts of wood tar · Boluohui alkaloids (the compounding ratio of wood tar and Boluohui alkaloids is 9:1), add 10 parts of castor oil and 5 parts of fatty alcohol polysaccharides in sequence on the basis of the above mixture Oxyethylene ether, make up to 100 parts with water + oil + xanthan gum (25:1:1.5), and stir at a stirring speed of 100-200 rpm for 10-30 minutes to obtain 30% wood tar Boluo Back to alkaloid smears.

Embodiment 2

[0099] Example 2: Preparation of 50% wood tar Boluohui alkaloid smear

[0100] At room temperature, take 50 parts of wood tar · Boluohui alkaloids (the compounding ratio of wood tar and Boluohui alkaloids is 4:1), add 10 parts of castor oil and 5 parts of fatty alcohol polyols in sequence on the basis of the above mixture Oxyethylene ether, make up to 100 parts with water + oil + xanthan gum (16:2:0.6), and stir at a stirring speed of 100-200 rpm for 10-30 minutes to obtain 50% wood tar Boluo Back to alkaloid smears.

Embodiment 3

[0101] Example 3: Preparation of 80% wood tar Boluohui alkaloid smear

[0102] At room temperature, take 80 parts of wood tar · Boluohui alkaloids (the compounding ratio of wood tar and Boluohui alkaloids is 7:3), add 10 parts of castor oil and 5 parts of fatty alcohol polyols in sequence on the basis of the above mixture Oxyethylene ether, make up to 100 parts with water + oil + xanthan gum (3:1:1), stir at a stirring speed of 100-200 rpm for 10-30 minutes, and then 80% wood tar boluo can be obtained Back to alkaloid smears.

Abstract

The invention discloses a sterilizing agent compounded by wood tar and macleaya cordata alkaloids and a preparation method and application of the sterilizing agent. The prepared plant-source synergiccompounded sterilizing agent is compounded by using the wood tar and the macleaya cordata alkaloids as the main components and adding auxiliaries, and the preparation form of the compounded sterilizing agent can be a micro-emulsion, soluble concentrate and a smearing agent. The compounded sterilizing agent contains 30-80% of wood tar, 0.1-10% of macleaya cordata alkaloids and the balance auxiliaries and is mainly used for preventing and treating rot, downy mildew, canker, soft rot and the like. The plant-source synergic compounded sterilizing agent has the advantages that the sterilizing agentdoes not contain any chemical pesticide components and is easy to degrade in environments, free of environment pollution and residual hazard, low in toxicity to human and livestock and good in environment compatibility, and germs cannot easily generate resistance to the sterilizing agent; the sterilizing agent can prevent and treat agricultural diseases such as the rot, the canker and the soft rot of fruit trees and vegetables; in addition, the sterilizing agent is relatively low in preparation cost and simple in application method, has a great application and popularization value in the preventing and treating of the diseases of the fruit trees and the vegetables and is an ideal novel pollution-free sterilizing agent.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a compound fungicide made of wood tar and bollia alkaloids, its preparation method and its application, and is mainly used for preventing and treating rot, canker, botrytis and frost on fruit trees and vegetables. Agricultural diseases such as mildew and soft rot. Background technique [0002] Downy mildew, gray mold, rot, soft rot, and canker are the main diseases on melons, fruits, and vegetables. They have a wide range of damage and are difficult to control. At present, the medicaments used to prevent and control these diseases are mainly chemical fungicides. However, the long-term use of a large number of chemical drugs has led to the emergence of problems such as drug resistance, environmental pollution, and harm to human health; The use of many chemical pesticides has had to be restricted. Searching for bactericidal active substances from the treasure house ...
