How to control the jujube bud weevil? Detailed control methods

Control of the jujube bud weevil: (1) Plastic film and toxic rope method: before adult weevils emerge from the soil in spring, in high-incidence areas bind a 20 cm wide plastic film around the jujube tree trunk for 1 turn, and tie a toxic straw rope soaked in a 1000-fold dilution of 2.5% deltamethrin around the middle, with the upper part of the film rolled upward to prevent the jujube bud weevil from climbing the tree, so that it dies after contacting the straw rope; (2) Pole beating method: in the morning when there is dew, beat the jujube trees with a pole, taking advantage of the weevil's death-feigning habit to make it fall to the ground, and spray 5% trichlorfon powder on the ground and on the jujube tree trunks in advance so that they are poisoned and die; (3) For chemical control, decamethrin, kuai shaling and others can be sprayed on the canopy to kill the pests.
