With the advent of winter, pesticides used by farmers have been greatly reduced. The remaining pesticides in the year and the pesticides to be used next year have entered the storage period. To protect the pesticides, the following eight points should be noted:
1. Anti-volatilization: Since most pesticides are volatile, precautions should be taken to seal them when storing pesticides to avoid reducing the efficacy of evaporation, polluting the environment and endangering human health.
2 All pesticides have different levels of toxicity. Therefore, it is important to store pesticides to prevent accidents. , accident prevention: should pay attention to four points: First, the best storage in a counter or wooden box, and lock, labeling. The second is that pesticides cannot be stored in the same room as feeds for grain, oil, food, and animals. Third, pesticides and fumigants should not be placed together with flammable and explosive materials (eg, gasoline, firecrackers, etc.), and they must not be stored in the bedroom or livestock house. Special attention should be paid not to places accessible to children so as to avoid have an accident. Fourth, paper packaging items and medicine bottles for pesticides must not be used for food, food, and feed.
3. Loss of anti-pesticide labels or user manuals: Pesticides purchased by farmers must keep pesticide labels and instructions for use. A small amount of pesticides that were bought back for zero should be labeled on the vials (bags). The labels have been lost or the labels are fuzzy. Unclear pesticides must be rewritten on paper with the name, usage, amount, expiration date, and scope of use, and be affixed to the bottle or bag for proper use.
4. Anti-metamorphism: Certain categories of pesticides should be stored. Can not be stored together with alkaline substances, ammonium bicarbonate, ammonium nitrate, etc.
5, anti-humidity: storage and storage of pesticides should be kept dry (relative humidity below 75%), and prevent moisture.
6, to maintain temperature: the higher the temperature, the more easily melted pesticides, decomposition, volatilization, and even burning explosion. Some bottled liquid pesticides tend to freeze when they encounter low temperatures, forming a block, or freezing the bottle. High-temperature pesticides should be stored in a cool, dry and ventilated place. The storage temperature should not exceed 35°C. Prevent cold temperature should pay attention to antifreeze, keep the temperature above 1 °C. A common method of frost protection is to cover the insulation with firewood, clam shell or unused quilts.
7, anti-light sun: pesticides used in brown bottles generally need to be protected from light, such as phoxim pesticides see light easily decomposed. Pesticides that need to be kept away from light, if exposed to light for a long time, can cause degradation and failure of pesticides. For example, after the emulsion pesticide has sun exposure, the emulsification performance deteriorates and the efficacy decreases. Therefore, it is necessary to avoid sunlight during storage.
8, against environmental pollution: the small amount of pesticides that have expired or remain in the field can not be littered in the field, can not pour ponds, streams, rivers or wells. Deep treatment should be taken to avoid polluting the environment.
