How to keep the remaining pesticides in winter
Flat washers are usually thin pieces of various shapes, used to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure. Such components are found in many materials and structures to perform various similar functions. Due to the limitation of the material and technology of threaded fasteners, the bearing surface of bolts and other fasteners is not large. Therefore, in order to reduce the compressive stress of the bearing surface and protect the surface of the connected parts, washers are used.

Don't mess with it. Before storing the remaining pesticides, read the instruction manual carefully and take the pesticides that have been ineffective in the wild. Do not throw them away in order to avoid poisoning and polluting the environment.
Don't mess with the label and instruction manual of the pesticide, and replace the damaged bottle and bag. For pesticides whose labels have been lost or blurred, the name, usage, dosage, expiration date, and scope of use must be rewritten on paper and attached to the bottle or bag for proper use.
It is necessary to pay attention to the implementation of sealed bottled liquid pesticides, which should have an inner cover and tighten the cap to avoid the volatilization of pesticides and cause air pollution. Bagged powder pesticides should be sealed with double-layer plastic bags to prevent moisture and agglomerate from deteriorating.
Pay attention to maintaining temperature. Most powder pesticides are susceptible to high quality at high temperatures. 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.
It is necessary to pay attention to maintaining dry powder pesticides and plant growth regulators, which 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%.
Pay attention to classified storage. According to chemical composition and properties, pesticides can be divided into three categories: acidic, alkaline and neutral. Acidic pesticides such as trichlorfon, dimethoate, dichlorvos, etc.; alkaline pesticides such as stone sulfur mixture, Bordeaux mixture, etc.; neutral pesticides such as 1605, methamidophos, phoxim and so on. 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.
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 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; they should not be stored in the bedroom and often with people and animals. Access to the area should be kept in a ventilated, dry, cool place.
It is necessary to check frequently for all kinds of pesticides to be kept, and to check regularly to prevent the loss of pesticide deterioration caused by the ground returning to the ground, the house leaking rain, and the packaging is broken.
