Addition agent for nicosulfuron oil-based suspension concentrate and nicosulfuron oil-based suspension concentrate

Abstract

The invention relates to an addition agent for nicosulfuron oil-based suspension concentrate. The addition agent is prepared by the following materials, by weight: 10-60% of nonylphenol polyoxyethylene ether, 10-50% of castor oil polyoxy ethyl ether, 5-20% of fatty alcohol polyoxy ethyl ether, 5-25% of alkyl benzene sulfonic acid and 5-40% of solvent oil. The invention further relates to nicosulfuron oil-based suspension concentrate. The novel addition agent for the nicosulfuron oil-based suspension concentrate is good in dispersibility and stable in performance, and can not only be used for preparing the nicosulfuron oil-based suspension concentrate of 4%, but also be used for preparing the nicosulfuron oil-based suspension concentrate of 20%. Active ingredients in the preparation are improved after the nicosulfuron oil-based suspension concentrate with a high concentration is prepared, using quantities of organic solvents and the addition agent are reduced, the pollution to the environment is reduced, and the cost can be reduced. Epoxidized soybean oil is further added to serve as a stabilizing agent, reduces decomposition rate of nicosulfuron, and maintains pesticide effect.

Description

technical field [0001] The invention relates to an auxiliary agent for pesticides, in particular to a special auxiliary agent for nicosulfuron dispersible oil suspension and nicosulfuron dispersible oil suspension containing the auxiliary agent. Background technique [0002] Nicosulfuron, also known as nicosulfuron, is an internal adsorbent that is absorbed through leaves, stems, and roots, and then transmitted to the meristem. The drug enters the corn plant and is quickly metabolized into inactive substances. It is safe for most corn varieties, so It is mainly used to control grass weeds, broadleaf weeds and sedges in corn fields. [0003] The current nicosulfuron oil pesticide is mainly oil suspension concentrate (OF). The so-called oil suspension concentrate (oil miscible flowable concentrate (oil miscible suspension)) refers to a liquid preparation with stable suspension of active ingredients, which is diluted with an organic solvent before use. 4% Nicosulfuron Oil Susp...
