Embodiment 1

[0020] Example 1: The dry injection preparation of 0.5% emamectin benzoate:

[0021] Take by weighing the former drug 0.56Kg of emamectin benzoate with a purity of 90%, 96.44kg of methyl alcohol, stir, and emamectin benzoate is completely dissolved in methanol; add 3.0kg The octylphenol polyoxyethyl ether (OP-10) was fully stirred and dissolved to prepare 100kg of 0.5% emamectin benzoate dry injection liquid.

Embodiment 2

[0022] Example 2: Preparation of 5% emamectin benzoate injection dry bactericidal liquid:

[0023] Take by weighing the former drug 5.56Kg of emamectin benzoate with a purity of 90%, 20.44kg of methyl alcohol and 70kg of tetrahydrofurfuryl alcohol, stir, and make emamectin benzoate completely in the solvent Dissolve; Add 4 kg of polyoxyethylene lauryl ether, fully stir and dissolve, and obtain 100 kg of dry injection liquid of 5% emamectin benzoate.

preparation Embodiment 3

[0024] Preparation Example 3: 12% emamectin benzoate tebuconazole dry injection preparation:

[0025] Weigh 4.44kg of the original drug of emamectin benzoate with a purity of 90%, 20kg of N,N-dimethylformamide, and dissolve the emamectin with N,N-dimethylformamide The former medicine of amectin benzoate; Add tetrahydrofurfuryl alcohol 62.16kg and purity again and be the former medicine 8.4kg of tebuconazole of 95%; Stir, make the former medicine of emamectin benzoate and tebuconazole Dissolve completely; add 5.0kg of octylphenol polyoxyethyl ether (OP-10), stir and dissolve, and then prepare 100kg of 12% emamectin benzoate tebuconazole liquid injection .

Abstract

The invention discloses a liquid formulation containing emamectin benzoate for trunk injection, the prepared liquid formulation for trunk injection comprises the following raw materials by weight percent: 0.1%-15.0% of emamectin benzoate, 1%-10% of emulsifier and the balance of solvent, wherein the sum of the percents of the raw materials is 100%. Or 1-20% of fungicide is added in the formula. The medicament is applicable to trunk injection for controlling various pests at fruit parts of economic forest trees, and can further control diseases of fruits of the economic forest trees while controlling the pests in the fruits of the economic forest trees. The control effect is better especially for damages by diseases and pests of the fruits of the economic forest tress with tall trunks, and the problem of inconvenience in application in the situations that the mountains are high, the roads are steep, the trunks are tall, and the application is carried out before and after houses around avillage can be further solved.

Description

technical field [0001] The invention relates to a dry-injection liquid preparation, in particular to a dry-injection liquid preparation containing emamectin benzoate, which is mainly applied through a trunk-injection method, and is suitable for preventing and controlling economic forest fruit pests and diseases. Background technique [0002] By injecting medicine through the trunk, the medicine directly enters the tree without polluting the environment and causing harm to humans, animals and other beneficial organisms. It is a very ideal environment-compatible and pollution-free pesticide application technology. After a lot of experimental research, Northwest Agriculture and Forestry University Pollution-free Pesticide Research Service Center has applied for a national invention patent "a tree desiccant", patent number: ZL99111357.8. Developed the first generation of dry liquid injection - 30% divos · Oxyle insecticidal dry liquid injection, and obtained the national pestici...
