Abstract

The invention discloses an auxiliary agent for a fluorosulfonic acid aqueous solution. The auxiliary agent comprises the following components in percentage by weight: 10-15% of polyglycerol ether, 20-30% of plant amine polyoxyethylene ether amine oxide, 15-20% of cocamidopropyl amine oxide, 10-15% of alkyl glycoside and the balance of water. The invention also discloses a fluorosulfonic acid aqueous solution containing the auxiliary agent and a preparation method of the fluorosulfonic acid aqueous solution. The fluorosulfonic acid aqueous solution is high in herbicidal activity and has a goodcontrol effect on various weeds in northeast cold regions, so that the speed of drug resistance of the weeds is greatly reduced, and the herbicidal activity of the fluorosulfonic acid aqueous solutionis improved.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an auxiliary agent for a fluorine-sulfon water agent and the fluorine-sulfon water agent prepared therefrom. Background technique [0002] Farmland weeds are a class of harmful organisms that seriously threaten the growth of crops. Weeds can cause an average 34% loss of crop yield, and their damage is much higher than that of pests and pathogens. At present, chemical herbicides are still the most economical and effective means of controlling weed damage in modern agricultural production. However, with the long-term and large-scale use of herbicides, many problems such as drug resistance and environmental pollution have been brought about. [0003] Fomesafen is a herbicide widely used in soybean fields. It has the advantages of wide herbicidal spectrum, good weeding effect, and safety to the environment and subsequent crops. It can be used both before and after soybean emergen...
