Precautions for storage of residual pesticides

Every year, farmers can't buy pesticides accurately, and they usually have some. In order to prevent accidents, from the point of view of safety, the remaining pesticides are best placed in wooden boxes and tagged outside. Pesticides should not be in the same room as food, vegetables and feed. Keep away from flammable and explosive materials, such as firecrackers, gunpowder, etc.; the original packaging bottles, bags can not be loaded with food and household daily necessities.

Most pesticides are volatile and should be sealed for storage. Evaporation of dimethoate, dichlorvos, phoxim and other gases can easily cause air pollution. Be sure to tighten the cap and seal it.

The pesticide label should not be lost. If the writing is unclear due to water and other reasons, it should be manually copied and attached to the outer packaging.

When not used up, the two pesticides should not be mixed in one bottle or bag to avoid chemical reaction failure. Some pesticides should be separated from each other by a large distance. For example, alkaline, acidic, and neutral pesticides may cause a decrease in efficacy, deterioration, or failure. The relative humidity of the stored pesticide should be kept below 75% to prevent agglomeration due to moisture. At the same time, it is also necessary to prevent high temperature. For example, when the emulsion pesticide is exposed to high temperature, it will destroy its emulsification performance and reduce the efficacy. Pesticide powders can reduce the efficacy at high temperatures. Pesticide should be stored in a cool, dry and ventilated place. The storage temperature should not exceed 35 °C. However, too low temperature will cause the liquid pesticide to freeze and freeze. It should be kept above 1 °C. The cold weather can be covered with straw, rice hull, etc. Keep warm.

According to the China Pesticide Network , many pesticides are afraid of sunlight, and long-term exposure will decompose and degrade the pesticides, so try to avoid light preservation. Deeply bury the pesticides that have failed or remain small, and do not dump them in ponds or rivers.
