Peach tree borer prevention measures
Peach aphids are concentrated on the new leaves, and it is necessary to timely and carefully spray 10% imidacloprid WP 3000-4000 times. In order to improve the control effect, a little neutral detergent powder can be added to the medicine, and Nisolon (thianthone) can also be added to control the adult spider mites of overwintering. In the last few years, locusts began to jeopardize the blossoming of peach trees, and the locusts were already visible in the flowering pods. If spraying drugs when flowering, it may affect fruit setting. It is recommended to use the method of germination and drying, ie, using 10% imidacloprid wettable powder, water 1:3 to 1:5, and coat 15-20 cm wide in the smooth place of the main trunk. The medicine ring, wrapped with plastic film or tape, has good control effect. If you apply Vaseline to the surface of the film, you can prevent spider mite damage. This less spraying can reduce the killing of natural enemies.
