The safe interval between pesticides refers to the period from the last application to the harvest of the crop, that is, the time from the spraying to the residual amount to allow the residual amount. Due to the different speeds of decomposition and disappearance of various chemicals, and the growth trend and season of various crops, the safety interval after application of pesticides is also different. In agricultural production, the time between the last spray and harvest must be greater than the safe interval, and crops are not allowed to be harvested during the safe interval. Therefore, understanding the safe interval of crops is of great significance to ensure the food safety of food and fruits and vegetables.
