There are three difficulties in the use of bagged pesticides.

A few days ago, when the industrial and commercial branch of the Fufu District of Zhangzhou City, Shanxi Province inspected the agricultural resources market, I heard many vegetable farmers report that the pesticides used for sterilization and treatment are mostly powders, and they are almost all packed in sealed plastic bags. And this packaging brings at least a "three difficulties" to the use of farmers.
The opening is difficult. Most of these plastic packaging materials are very strong, and it is very convenient to cut them with scissors. However, farmers do not carry knives or scissors with them when they spray, but they have to use their teeth to bite when they can not be opened by hand. It is neither hygienic nor safe.
It is difficult to measure. Although the proportion of the ingredients has been indicated on the package, after the opening, how much is poured into the sprayer exactly fits the scale, and the proportion of the pesticide is mostly calculated in grams, so it cannot be accurately grasped, not too much, or it is poured. not enough. More is easy to cause phytotoxicity, and less and less can not play a preventive role.
It is difficult to save. Although there are many specifications for bagged pesticides today, once they are opened, it is very common to use them once. Once they are left, the pesticides in the bags are not easy to store because they cannot be sealed. First, they are easy to be scattered and the poultry and livestock are mistaken. Food; Second, it is easy to volatilize and reduce the use of pesticides.
In view of the above, many farmers are looking forward to improving the packaging design of bagged pesticides. For example, you can design an easy-opening place, and print a clear mark, not only easy to open, but also easy to fit, can not be used at one time, can also be used for the next time. China Pesticide Network recommends to promote unit packaging, a bag is just equipped with a spray can, which is convenient and safe.
