specific Embodiment approach 1

[0013] Specific embodiment 1: The environment-friendly potato field herbicidal composition of this embodiment consists of 30-85 parts of acetochlor, 1-30 parts of soybean oil, 5-20 parts of acetochlor-specific emulsifier and 3-30 parts by weight Composed of turpentine oil; wherein the special emulsifier for acetochlor is composed of calcium dodecylbenzenesulfonate, phenylethylphenol-based polyoxyethylene ether, and castor oil polyoxyethylene ether according to (1~3): (1.5~4 ):(2~8) by mixing at normal temperature and pressure.

[0014] The preparation method of the above-mentioned environment-friendly potato field herbicidal composition is carried out according to the following steps: 30 to 85 parts of acetochlor, 1 to 30 parts of soybean oil, 5 to 20 parts of acetochlor special emulsifier and Add 3-30 parts of turpentine oil into the reaction kettle, stir at a speed of 80-100r / min for 30-60min at normal temperature and pressure, and complete the preparation of the environment...

specific Embodiment approach 2

[0017] Specific embodiment two: this embodiment differs from specific embodiment one in that: the environment-friendly potato field herbicidal composition consists of 30 parts of acetochlor, 30 parts of soybean oil, 20 parts of acetochlor special emulsifier and 20 parts by weight Composed of pine light oil. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0018] Specific embodiment three: this embodiment differs from specific embodiment one in that: the environment-friendly potato field herbicidal composition consists of 50 parts of acetochlor, 15 parts of soybean oil, 12 parts of acetochlor special emulsifier and 23 parts by weight. Composed of pine light oil. Others are the same as in the first embodiment.

Abstract

The invention relates to a weeding combination and particularly relates to an environment-friendly potato field weeding combination. The combination aims to solve problems that a conventional weedicide is not environment-friendly, difficult to operate, not stable in control effect and high in cost. The environment-friendly potato field weeding combination is composed of acetochlor, soybean oil, an emulsifier for the acetochlor and pine-stump light oil, wherein the emulsifier for the acetochlor is formed by mixing calcium dodecyl benzene sulfonate, phenethyl phenol polyoxyethylene ether and castor oil polyoxyethylene ether. The environment-friendly potato field weeding combination disclosed by the invention is capable of effectively controlling annual gramineous weeds and part broad-leaf weeds propagated by small seeds in potato fields, safe to potatoes, stable in weeding effect and environment-friendly; compared with the conventional weedicide using a turpentine solvent, the combination using the pine-stump light oil has the advantages that the production cost is reduced and the weed controlling effect of acetochlor missible oil taking the pine-stump light oil as the solvent is better through beneficial constituents such as wood vinegar and the like in the pine-stump light oil. The combination disclosed by the invention is safe in formula, convenient to use and easy to popularize.

Description

technical field [0001] The present invention relates to a herbicidal composition. Background technique [0002] Potato is one of the main economic crops in my country, and weeds in potato field seriously affect the quality and yield of potato. At present, the application of chemical herbicides has greatly improved labor production efficiency, reduced labor intensity, saved expenses, and effectively controlled the growth of weeds. However, the accompanying environmental pollution has also attracted more and more attention. [0003] The selective pre-emergence treatment herbicides trifluralin, pendimethalin, napropamide, dimethalin, etc. are often used for soil sealing treatment before seedlings in potato fields. [0004] Trifluralin, acetochlor or metolachlor are often used for soil sealing treatment after sowing and pre-emergence of potatoes. They have good control effects on annual grass weeds and broad-leaved weeds with small seeds, but trifluralin spray Unevenness affec...
