Embodiment 1

[0021] 15 parts by weight of pretilachlor and 1 part by weight of alkylphenol polyoxyethylene ether phosphate, 1 part by weight of polyoxyethylene polyoxypropylene ether block copolymer, 3 parts by weight of phenylphenol polyoxyethylene Ether, mix uniformly, absorb with the white carbon black of 20 weight parts, then with the bensulfuron-methyl of 1.5 weight parts, the sodium lignosulfonate of 2 weight parts, the sodium methylene dinaphthalene sulfonate of 1 weight part, 2 The Kathon preservative in parts by weight is uniformly mixed and pulverized by an airflow mill to obtain mother powder. Mix the parent powder and wheat straw powder supplemented to 100 parts by weight, and then mix with 10 parts by weight of paraffin and 6 parts by weight of methyl ester soybean oil to obtain a finished product of 16.5% pretilachlor-bensulfuron-methyl paddy field weeding throwing powder.

Embodiment 2

[0023] The pretilachlor of 20 parts by weight is mixed with the sorbitan phosphate of 2 parts by weight, the emulsifier Tween of 1 part by weight, the methyl naphthalene formaldehyde polymer of 3 parts by weight, with 20 parts by weight of white carbon black Adsorption, then mixed with 2 parts by weight of bensulfuron-methyl, 2 parts by weight of methylenebis(sodium methylnaphthalene sulfonate), 1 part by weight of sodium lignosulfonate, and 2 parts by weight of sodium benzoate After being pulverized by a jet mill, the mother powder is obtained. Mix the mother powder and the corn stalk powder supplemented to 100 parts by weight, and then mix them with 8 parts by weight of paraffin and 8 parts by weight of esterified soybean oil to obtain 22%% pretilachlor Bensulfuron-methyl paddy field weeding and throwing Finished powder.

Embodiment 3

[0025] Mix 10 parts by weight of pretilachlor with 2 parts by weight of sorbitan phosphate, 1 part by weight of emulsifier Tween, and 3 parts by weight of phenylphenol polyoxyethylene ether, and use 10 parts by weight of white carbon Black and 5 parts by weight of diatomite adsorption, and then with 1.5 parts by weight of bensulfuron-methyl, 2 parts by weight of methylene bis (sodium methyl naphthalene sulfonate), 1 part by weight of methylene bis Sodium naphthalenesulfonate and 2 parts by weight of sodium benzoate are uniformly mixed and pulverized by an airflow mill to obtain mother powder. Mix the mother powder with the rice straw powder supplemented to 100 parts by weight, and then mix it with 10 parts by weight of paraffin and 8 parts by weight of glyceric acid ester to obtain the finished product of 11.5% pretilachlor Bensulfuron-methyl paddy field weeding throwing powder .

Abstract

The invention discloses water field weeding throwing powder which comprises the following components in parts by weight: 1-25 parts of a pretilachlor raw medicine, 0.5-4 parts of bensulfuron methyl, 1-20 parts of a surfactant, 1-25 parts of an adsorbent, 1-25 parts of an oil substance, 1-10 parts of preservative additives and 15-70 parts of a solid core material, namely crop straw powder. An environmental-friendly floating material, namely the crop straw powder, is used in the water field weeding throwing powder disclosed by the invention. According to a preparation formula, surfactants such as a dispersion are used, so that medicinal powder can be floated and dispersed on a water surface after being applied, are floated and dispersed under the action of the surfactants and natural wind power, are dispersed to a whole field water surface within a short time, and are sunk into soil from the water surface. The medicine has the characteristics of being simple in production process, convenient to store and transport, time and labor saving in application, long-lasting in medicine effect, and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a paddy field weeding throwing powder and a preparation method thereof. Background technique [0002] With the improvement of the precision of the target of pesticide application and the increasing emphasis on environmental protection, some dosage forms that pollute the environment are gradually eliminated and replaced by new dosage forms with high efficiency, low toxicity and environmental protection, which are gradually promoted and applied. . In recent years, the research on labor-saving technology of paddy field weeding has gradually been extensive and in-depth. The paddy field weeding throwing powder has simple processing technology, safe and convenient storage and transportation, time-saving and labor-saving application, and stable and long-lasting drug effect. It has obvious practical value and development prospect. The action point of the mixture of pret...
