Abstract
The present invention is formed from acetochlor and emulsifier, the mass percentage content of the acetochlor effective component in the acetochlar raw medicine is 95.0-100, its emulsifier is formed from calcium dodecylbenzenesulfonate and nouylphenol polyethenoxy ether, their mass ratio is 1:1-1.4 and the dose of the emulsifier is 5-12% of total mass of acetochlar solventless emulsifiable concentrate. Said invention is tow in toxicity, safe for production, transportation, storage and application, can reduce toxicity to crops, people and animals, and can reduce environmental pollution, does not produce insecticide burn and its inserticidal effect is good.
Description
Technical field: the present invention relates to a kind of agricultural chemicals.
Background technology: existing missible oil is that pesticide original medicine ratio in accordance with regulations is dissolved in the organic solvent, the oily liquids of the homogeneous phase transparent that adds a certain amount of agricultural chemicals emulsifier special again and make, contain more organic solvent in traditional missible oil, because organic solvent belongs to inflammable thing, producing, firing accident all very easily takes place in transportation and the keeping, and organic solvent has the medicament of promotion to the crop epidermis, zoodermic osmosis, so it has increased the chance of medicament to chemical injury of crops and person poultry poisoning, and a large amount of organic solvents constantly is dispersed into natural world, can cause environmental pollution, influence natural, ecological.
Summary of the invention: the present invention overcomes the defective that the organic solvent existence is caused in traditional missible oil, thereby provide a kind of solvent-free missible oil of Acetochlor of not dosing any organic solvent, it is made up of acetochlor tc and emulsifier, the quality percentage composition of Acetochlor active ingredient is 95.0～100 in the acetochlor tc, described emulsifier is made up of calcium dodecyl benzene sulfonate and polyoxyethylene nonylphenol ether, the mass ratio of calcium dodecyl benzene sulfonate and polyoxyethylene nonylphenol ether is 1: 1～1.4, and the consumption of described emulsifier accounts for 5～12% of the solvent-free missible oil gross mass of Acetochlor.The present invention is the preparation that acetochlor tc and emulsifier are directly mixed, and does not wherein dose any organic solvent, and its toxicity is low, and production, storing and safe in utilization alleviate the toxicity to crop and people and animals, reduces the pollution to environment; Its good drug efficacy does not produce poisoning, increase yield significantly; And its technology is simple, and is easy and simple to handle, and the materials kind is few, has good value for applications.
