Pay attention to five points in the winter to keep the remaining pesticides

In the autumn, some farmers have not used up the pesticides, and they have to do “five attentions” during the storage process. First, pay attention to the implementation of the seal. Some pesticides are volatile and invalid, causing air pollution. When storing, the cap must be tightened and sealed.

Second, pay attention to maintaining the temperature.

Most powder pesticides are susceptible to quality at elevated temperatures. The higher the temperature, the easier the pesticide will melt, decompose, volatilize, and even burn and explode. Some emulsion pesticides will also destroy their emulsification performance and reduce the efficacy after encountering high temperature. Some bottled liquid pesticides freeze when they encounter low temperature, form a block, or cause the bottle to burst. Keep the indoor temperature above 1 °C when storing such pesticides. In addition, the octyl sulphate pesticide is afraid of light, and the long-term exposure to light will cause the decomposition and deterioration of the pesticide, and avoid high temperature and sun exposure during storage.

Third, pay attention to keep dry. Powder pesticides and plant conditioners are easy to absorb moisture and agglomerate. Therefore, the place where the pesticides are stored should be kept dry to prevent rain and snow. Also leave a window for ventilation and keep the humidity below 75%.

Fourth, pay attention to the classification and storage. Pesticides are classified as alkaline, acidic and neutral. Alkaline pesticides include enemy scorpion, stone sulphur mixture, Bordeaux mixture, etc.; acidic pesticides include deltamethrin; neutral pesticides include gram sputum, 1059 and so on. These three different types of pesticides should be stored separately during storage and storage, and the distance should be kept above 0.5 meters. Otherwise, the pesticides will be deteriorated. In addition, the two kinds of pesticides that cannot be used can not be mixed in one bottle to avoid failure.

Fifth, we must pay attention to prevent accidents. All pesticides have different degrees of toxicity. In storage, it is best to put them in a counter or wooden box and lock them outside. Pesticides should not be stored in the same room as grains, oils, beans, seeds and vegetables; emulsifiables and fumigants should not be combined with flammable and explosive materials such as matches, oil, diesel and firecrackers to avoid accidents.
