In recent years, with the popularization and application of agricultural science and technology, and the promotion of various types of pesticides, the topics related to the improvement of pesticide packaging have also received increasing attention. Pesticide research departments and manufacturers have also done a lot of work for packaging improvement. However, from the situation held by the Dingxi County Bureau of Quality and Technical Supervision and the Dingye County Bureau of Industry and Commerce in Shanxi Province, there are two basic problems that have not been fundamentally resolved. One is the issue of farmers' direct contact with pesticides during spraying, and the other is the measurement of pesticides when dispensing. Therefore, in the process of improvement of pesticide packaging in the future, these two problems may be taken as a breakthrough to improve. Because the first question is directly related to whether farmers are hurt when spraying, and the second question is related to the scientific and accurate use of pesticides.
According to relevant data, there is a bottle of a built-in meter in foreign countries. When using, only need to squeeze the bottle by hand, so that the liquid will rise through a pipe into the meter. After reaching the required dose, open the lid of the meter and pour the medicine directly into the water so that the medicine enters the sprayer from the pesticide bottle. In the process, it can not only accurately measure, but also avoid contact with the operator's hands, so it has more. In addition, according to relevant information, a water-soluble air-tight plastic packaging bag is used to make the pesticide formulation into a small-quantity package. When it is used, only a certain number of drug packages need to be immersed in a sufficient amount of water, and the packaging bag can be dissolved by itself. The agent is evenly dispersed in the water. This method completely eliminates direct contact between the operator and the pesticide. I heard that China has also successfully researched water-soluble plastic packaging bags that can be used to ship liquid pesticide formulations. It hopes to be available soon and serve agriculture.
Some foreign countries, can we learn from it? Something I myself hope to get listed early. This is the hope of the majority of farmers' friends to improve pesticide packaging.
