In recent years, with the popularization and application of agricultural science and technology and the promotion of various types of pesticides, more and more attention has been paid to the improvement of pesticide packaging. Pesticide research institutes and manufacturers have also done a lot of work to improve pesticide packaging. Bags, bottles, but the effect is not great, still can not satisfy the farmers. For the two issues mentioned earlier by the author, it may be used as a focus of improving pesticide packaging for a period of time in the future.
According to relevant information, a water-soluble air-tight plastic packaging bag is used to make the pesticide formulation into a small-quantity package, preferably a bag that can dissolve a sprayer barrel, and only a certain amount of the medicine package needs to be immersed in a sufficient amount. In water, the bag can be dissolved by itself and the drug can be evenly dispersed in the water. This method can completely solve the problem of direct contact between operators and pesticides. In addition, there are reports that a pesticide bottle with a built-in meter is used abroad. When it is used, it can be squeezed by hand and the drug solution can rise through a catheter and enter the measurement device. When the required dose is reached The meter lid can be opened to pour the medicine directly into the water. In the process of the medicament entering the nebulizer from the vial, both the precise measurement and the operator's hands can be prevented from contacting with the pesticide.
Improvements in pesticide packaging should also be changed. Some foreign countries, we can learn from it; their own, can be listed early? We look forward to!

One is the problem of direct contact with pesticides when pesticides are sprayed, and the other is when pesticides are dispensed. Measurement problems.
