Pesticide applying method using biopesticide to control peach tree insect disease in whole process

The invention discloses a pesticide applying method using biopesticide to control peach tree insect diseases in a whole process; the method comprises the following steps: selecting a biopesticide, a bactericide and a nutrient solution with consistent medical property; mixing the agents according to peach tree needs; using water to dilute the mixture so as to obtain a composite soup; applying the mixture soup. The method uses no chemical pesticide to control insect diseases in the peach tree plantation period; the method can improve peach tree disease resistance ability according to biopesticide functions and complementation, high efficiency and low quantity principles, thus effectively controlling peach tree insect diseases, and producing healthy and qualified peaches. The method applies biopesticide and scientific application method to control pesticide residual; the whole growing period of the peach tree employs the biopesticide to control insect diseases according to rainfall in different years, thus obtaining good control effect; the method is suitable for large field popularization and application in insect disease control of organic peach production bases.
