Problems solved by technology

However, with the widespread use of paraquat, incidents of paraquat poisoning or skin contact burns continue to occur, so that countries or regions such as the European Union have banned or restricted the use of paraquat
Local farmers had to choose other herbicides with higher cost and slower acting speed for weed control, and even resumed the most time-consuming and inefficient manual weeding operation

Abstract

The invention belongs to the technical field of pesticide and relates to a water-soluble paste agent containing paraquat dichloride. The water-soluble paste agent comprises 0.5-45% of paraquat dichloride amounting to 0.362-32.58% of paraquat cation, 5-40% of surfactant, safe auxiliary components of emetic, warning coloration, stink agent and bitter agent, etc. and the balance of water. According to the invention, paraquat is processed into a paste agent, which can effectively avoid human or animal skin calcination caused by splashing of paraquat preparation; because the water-soluble paste agent has low fluidity, accidental taking or impulse swallow is reduced, and safety of the paraquat is enhanced substantially.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a water-soluble ointment containing paraquat dichloride. technical background [0002] Paraquat, a quick-acting contact-killing bipyridine herbicide, is currently one of the most widely used herbicides in the world. Its global sales and usage are second only to glyphosate, ranking the second largest herbicide agent products. However, since paraquat has strong acute toxicity to humans or other mammals, and there is no effective antidote, once paraquat is swallowed by mistake or intentionally, without timely and correct rescue treatment, it will cause serious harm to human beings. or animals causing serious injury or even death. [0003] In order to improve the safety of paraquat, especially for human beings, the International Food and Agriculture Organization stipulates that three safety auxiliaries must be added to paraquat preparations—triazol pyrimidinone, odorant and warnin...
