Problems solved by technology

[0003] At present, in agricultural production, the excessive use of pesticides is seriously endangering our health. According to the literature survey, paraquat (1-1-dimethyl-4-4 bipyridyl cationic salt) is a fast-killing herbicide, It can be quickly absorbed by green plants to make them die, so farmers will spray herbicides during the growth of crops in order to quickly weed weeds. Although, herbicides have a killing effect on crops, and then the medicinal properties of herbicides will be absorbed by crops, so , the crops will contain a certain amount of toxicity, and long-term consumption will cause great harm to the human body. However, due to the low content in the crops, and there is no testing material on the market that can quickly and accurately detect the content of paraquat
