Improper storage of pesticides in winter can cause human or livestock poisoning or death. The author believes that in order to ensure the safety of humans and animals and the quality of pesticides, the following seven precautions must be taken to store pesticides in the winter. Accident prevention In order to avoid accidents, pesticides should be placed in special counters or special wooden boxes, locked outside, and then labeled. Pesticide paper packaging items and medicine bottles must not be used for food, food, and feed. Two anti-labels were lost. Farmers purchased pesticides to protect the original labels. A small amount of pesticides that were bought back and bought back should be labeled on the medicine bottles (bags). The subsidy that has been blurred or the original label is missing, prevents the time from being clearly identified. Three anti-mixed pesticides are strictly prohibited from being stored in the same warehouse as food, feed, vegetables, fruits, food, and daily necessities. Can not be stored together with alkaline substances, ammonium bicarbonate, ammonium nitrate, etc. The chemical properties of the four anti-destructive pesticides are acidic, neutral and alkaline. Pesticides of different nature should be stored separately or stored at a distance of 0.5 meters or more. Five moisture-proof pesticides are easy to absorb moisture and agglomerate. Special warehouses or wooden boxes should be placed in a dry place to prevent leakage, and windows should be used for ventilation and ventilation. Relative humidity should generally be kept below 80%. Six high-temperature sun-proof pesticides can not be exposed to high temperatures and sunlight. For example, multi-insecticide is a new type of broad-spectrum insecticide composed of two active components: cypermethrin and trichlorphyrin. Store in a cool, dry and well-ventilated place. The storage temperature should not exceed 35°C. After the sun exposure of the emulsion pesticides, the emulsification performance deteriorated and the efficacy decreased. Therefore, where pesticides are released, they must be protected from high temperatures and sunlight. Seven antifreeze emulsion pesticides will freeze after freezing, and some liquid pesticides will freeze the bottles due to freezing, so pay attention to antifreeze. The way to prevent freezing is to cover the insulation with rice straw and clam shells. China Agricultural Network Editor
