Nowadays, it is very common for farmers to use the remaining chemical fertilizers and pesticides together. Many farmers do not understand the properties of chemical fertilizers and pesticides. I do not know that the combination of the two will have undesirable effects. (1) It is easy to decompose the pesticide. Most of the pesticides are neutral or acidic, and the chemical reaction occurs when the alkali is met, while the ammonium bicarbonate used at present is a basic fertilizer. This fertilizer is easy to evaporate ammonia gas during storage and is then combined with moist air. The formation of alkaline substances, resulting in the decomposition of pesticides failure or destruction of physical and chemical properties, resulting in knots solidarity block, reduce the efficacy of pesticides. (2) Easily cause explosion or burning accidents. Ammonium nitrate is also one of the commonly used chemical fertilizers in rural areas. It can be exposed to sunlight, impact, or high temperatures and explode naturally. Once combustibles and pesticides such as dimethoate and 1605 are encountered, combustion can also occur. If chemical fertilizers and pesticides are stored in large quantities, the effect will be more serious. (3) Corrosion of pesticide packaging will cause unnecessary trouble for the use of pesticides. When acidic fertilizers such as superphosphate are stored, free acids are volatilized, making the humid air in the warehouse acidic, and most pesticides are easily corroded and damaged in an acidic environment. In addition, due to the similar appearance of some chemical fertilizers and pesticides, it is easy to take the wrong ones when they are used and cause poisoning in humans and animals.
