How to preserve pesticides in winter
Many pesticide distributors choose pesticide winter storage in the winter. The purpose is to prevent tight supply in the coming year. When storing pesticides, keep the environment dry and avoid direct sunlight. So what should be paid attention to when storing pesticides?
1, sealed
Sealing measures should be taken when storing pesticides. The caps must be tightened during storage to ensure sealing.
2, insulation
Be careful to keep the temperature too high or too low. Most powder pesticides are susceptible to quality at elevated temperatures. When the temperature is too high, the pesticide will easily melt, decompose, volatilize, and even burn and explode. Some emulsion pesticides tend to destroy their emulsification performance and reduce the efficacy after encountering high temperature. Some bottled liquid pesticides tend to freeze when they encounter low temperature, form a block, or freeze the bottle. Keep the room temperature when storing such pesticides. Above 1 °C.
3, protected from light
Pesticides in brown bottles generally need to be stored in the dark. Pesticides that need to be protected from light, if exposed to light for a long time, will cause decomposition and deterioration of pesticides, so it is necessary to avoid sun exposure during storage.
4, moisture
Powder pesticides and plant conditioners are easy to absorb moisture and agglomerate, and the place where the pesticides are stored should be kept dry and protected from moisture. There should also be windows for ventilation and relative humidity below 75%.
5, classified and kept
Pesticides are chemically classified into basic, acidic and neutral. Pesticides of different chemical nature should be stored and kept at a certain distance during storage and storage. Otherwise, chemical reactions will occur in the pesticides, resulting in reduced efficacy, deterioration or failure. In addition, different pesticides that cannot be used can not be mixed in one bottle to avoid failure.
6, security
Pay attention to prevent accidents when storing pesticides. From the safety point of view, you should pay attention to 3 points: First, it is best to store it in a counter or wooden box during storage, and to lock it outside. Second, pesticides cannot be stored in the same room as grain, oil, beans, seeds, vegetables, food, and animals. Third, the emulsifiable and fumigant pesticides should not be placed together with inflammable and explosive materials (such as matches, gasoline, motor oil, firecrackers, etc.), and should not be stored indoors or in animals, poultry houses, or nearby. A place where children can reach.
7, environmental protection
A small amount of pesticides that have failed or remain cannot be dumped in the field, and cannot be poured into ponds, streams, or rivers. Deep burial should be taken.
8, properly keep the pesticide label and instructions for use
The following are usually found on pesticide labels or instruction manuals. Active ingredient content; control object, dosage and method of use; safety interval; precautions, etc. The above content must be clear before using the pesticide in the coming year. Therefore, the label and instruction manual of the pesticide must be preserved. For pesticides whose labels have been lost or whose labels are illegible, they must be re-applied to the bottle or bag for preparation. use correctly.
