1. Don't throw it away: Before storing the remaining pesticides, read the instruction manual carefully and take the pesticides that have been ineffective in the field for deep burial. Do not throw them away in order to avoid poisoning and polluting the environment.
2, to save the label: save the label of the pesticide and instructions for use, and replace the damaged bottles, bags and other packaging in a timely manner. For pesticides whose labels have been lost or blurred, the name, usage, dosage, expiration date, and scope of use must be re-written on the bottle and attached to the bottle or bag for proper use.
3, should pay attention to the implementation of the seal: bottled liquid pesticides, must have an inner cover, and tighten the cap to avoid the failure of pesticide volatilization, resulting in air pollution. Bagged powder pesticides should be sealed with double-layer plastic bags to prevent moisture and agglomerate from deteriorating.
4, should pay attention to maintain temperature: most powder pesticides in high temperature conditions, its quality is easily affected. The higher the temperature, the easier the pesticide will melt, decompose, volatilize, and even burn and explode. Some emulsion pesticides are easy to destroy their emulsifying properties 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, and should be kept in the storage of such pesticides. The indoor temperature is above 1 °C. In addition, phoxim pesticides are afraid of light, and long-term exposure to light can cause decomposition and deterioration of pesticides. Avoid high temperature and sun exposure during storage.
5, should pay attention to keep dry: powder pesticides and plant growth regulators, it is easy to absorb moisture and agglomeration, therefore, the place to store and store pesticides should be kept dry, to prevent leakage of rain and snow. Also leave a window for ventilation and keep the humidity below 75%.
6, should pay attention to the classification and storage: pesticides can be divided into acidic, alkaline, neutral three categories according to chemical composition and properties. Acidic pesticides such as trichlorfon, dimethoate, dichlorvos, etc.; alkaline pesticides such as stone sulfur mixture, Bordeaux mixture, etc.; neutral pesticides such as phoxim. These three different pesticides should be stored separately during storage and storage, and the distance should be kept above 0.5 meters. Otherwise, the pesticides will affect each other and cause deterioration. In addition, the two kinds of pesticides that cannot be used can not be mixed in one bottle to avoid failure.
7, should pay attention to prevent accidents: all pesticides have different degrees of toxicity, it is best to put them in a counter or wooden box during storage, and to lock outside. Pesticides should not be placed together with grain, oil, seeds, feed, vegetables, etc.; emulsions and fumigants should not be placed together with flammable or explosive materials such as matches, oil, firecrackers, etc.; they should not be stored in the bedroom and often in and out of humans and animals. The place should be kept in a ventilated, dry and cool place.
8. Always check: All kinds of pesticides to be kept should be inspected regularly to prevent the loss of pesticide deterioration caused by the ground returning to the tide, the house leaking rain, and the packaging is broken.
