The long white borer is harmed by nymphs and female adults who suck the sap of tea trees, and the trees in the affected tea gardens are weak in growth, the leaves are sparse and thin, the tea plantations are not old before they are old, the tea yield and quality are significantly reduced, and when severe, they can lead to the death of large-scale tea gardens. What is there to prevent and improve this from growing tea plants? What should we do to mitigate our losses once it has happened?
Methods for the control of long white borer
1. Seedling inspection, tea garden in the new district, tea seedling cuttings must be inspected before planting; seedlings must be transported from the nursery without long white beetles; if it is found that there are long white borers on the tea seedlings, they should be completely eliminated during the peak of nymph incubation.
2. Strengthen the management of tea gardens, apply fertilizer reasonably, pay attention to the cooperation of nitrogen, phosphorus and potassium; weed in time, cut off long branches, clear and bright feet, ventilation and light transmission, and avoid closure; low-lying tea gardens, pay attention to ditching and drainage.
3. Protect natural enemies, prune the insect branches, it is best to concentrate in the low-lying place of the leeward wind of the tea garden, and then burn it after the bee feathers; when the drug is controlled, the type of agent with a short residual effect period and little impact on the beneficial insects should be selected.
