Control methods of jujube bud weevil

Prevention and control of jujube bud weevil: ⑴ film poison rope method: before adults are unearthed in spring, 20 cm wide plastic film is used to bind the trunk of jujube tree in high incidence area for 1 week, the middle part is bound with poisonous grass rope soaked in 1000 times liquid of 2.5% deltamethrin, and the upper part of the film is rolled upwards to prevent jujube bud weevil from getting on the tree and die when exposed to grass rope poisoning. ⑵ pole hitting method, when the water pole is exposed in the morning, the pole hits the jujube tree and uses the weevil to make a false landing, while spraying 5% trichlorfon powder on the ground and the trunk of the jujube tree in advance, causing it to be poisoned to death; ⑶ chemical control can be used to kill pests by spraying the canopy such as the enemy, Kuaishuiling and so on.
