The invention discloses a method for killing
caffeine lysimachia christinae in a
caffeine trunk by using a soaking device, and belongs to the technical field of
caffeine pest control. The invention relates to a simplified method for killing caffeine
lysimachia christinae in a caffeine
trunk by using a soaking device. The method comprises the following steps: firstly, removing
insect-free side branches from branches and trunks which are collected in a coffee garden and are damaged by caffeine, classifying the branches and trunks according to
diameter grades, and
processing the branches and trunks into specific lengths; secondly, the inundator is placed in a place where the sun is directly irradiated, affected branches of the same
diameter level are bound into a unit and placed in the inundator, after all the affected branches are placed, a submerged heavy object is used for pressing the soaked affected branches to prevent the affected branches from floating upwards, then a water outlet valve is closed, clear water is injected, and a cover is covered; 3, soaking the damaged branches in a soaking device for a period of time; and step 4, after all the caffeinia in the affected branches die, opening a water outlet valve, draining water in the soaking device, opening a cover of the soaking device, taking out the affected branches, and completing soaking. The soaking method effectively solves the problems of long soaking time, low efficiency, risk of flying out of adults and the like of the injured branches of the coffee jettisonia, and is a simple, practical, efficient and low-
pollution soaking method for the injured branches of the coffee jettisonia. The soaking method for the injured branches of the coffee jettisonia effectively solves the problems of long soaking time, low efficiency and the like of the injured branches of the coffee jettisonia.
