There are five points to note when keeping pesticides in the fall
In the autumn, some pesticides purchased by some farmers have not been used up, and “five attentions†should be made during the storage process. First, pay attention to the implementation of the seal. Some pesticides are volatile and cause air pollution. The bottle caps must be tightly tightened during storage and sealed. Second, pay attention to maintaining the temperature. Most powdered pesticides are susceptible to quality at high temperatures. The higher the temperature, the more easily the pesticide melts, decomposes, volatilizes, and even burns and explodes. Some emulsion pesticides can also destroy their emulsifying properties and reduce their efficacy after they encounter high temperatures. Some bottles of liquid pesticides freeze when they encounter low temperatures, forming a block, or the bottle burst, in the preservation of such pesticides should maintain the room temperature above 1 °C. In addition, pungent sulfuric acid pesticides are afraid of light, long-term exposure to light exposure, will cause decomposition and deterioration of pesticides, in the storage to avoid high temperatures and sunlight. Third, pay attention to keep it dry. Powder pesticides and plant regulators, it is easy to absorb moisture and agglomerate. Therefore, the place where custody and storage of pesticides should be kept dry to prevent rain and snow. Also have windows to allow ventilation, keeping the relative humidity below 75%. Fourth, we must pay attention to classified storage. Pesticides are classified as alkaline, acidic and neutral. Alkaline pesticides include propanil, lime sulfur, Bordeaux mixture, etc. Acidic pesticides include deltamethrin, etc. Neutral pesticides include Keyusan, 1059 and others. These three kinds of pesticides of different nature should be stored separately during storage and storage, and the distance should be maintained at 0.5 meters or more. Otherwise, the deterioration of pesticides will be lost. In addition, the use of two kinds of pesticides can not be mixed in a bottle, in order to avoid failure. Fifth, we must pay attention to preventing accidents. All pesticides have different degrees of toxicity. It is best to store them in special counters or wooden boxes and keep them locked outside. Pesticides should not be stored in the same room as grain, oil, beans, seeds and vegetables; pesticides and emulsifiers and fumigants should not be placed together with flammable and explosive materials such as matches, oil, diesel, and firecrackers to avoid accidents.
