Tea green leafhopper

Intercropping with sweet-scented osmanthus or planting trees, etc., weeding weeds in the autumn and winter, providing wintering shelters for spiders and small bees to enhance ecological control potential. During the peak period of the insect population, timely and diligently collect the weeds in the tea line. The field that meets the control index can be sprayed with the following agents: tea saponin water, thiazide, high chlorofluorocarbon microcapsule suspension-suspending agent, indoxacarb EC, azadirachtin liquid, sophora flavescens and cucurbitine Aqueous agent, chlorfenapyr suspension, azole amide suspension, carbaryl thiamethoxam water-dispersible granules, and the like.

Tea è –

Protect and utilize important natural enemies such as the tea mites, the white velvet bee and the spider, and avoid the use of chemical pesticides during the peak period of the bee sting. In combination with the tea plantation in the autumn, the worms in the topsoil are removed; the chicken mites are placed; the larvae have obvious centers before the age of 3, and can be artificially killed. The insecticidal lamp is installed in the tea plantation of the tea tree, and the insects are turned on at the peak of the feathering to trap the adult. In the initial period of the cockroach cockroach, 3 to 5 sets of tea scorpion sex pheromone traps per acre are placed, and a large number of male worms are trapped and killed.

When the effects of other control measures are not obvious, the plant-derived pesticides and biological pesticides should be used preferentially, the use of chemical pesticides should be minimized, and the larvae can be controlled by the tea scorpion prion preparation. The control should be controlled at the age of 1~2, and the tea should be used with the liquid medicine. The leaf layer leaves are sprayed evenly on the front and back sides to fully exert the virus. Optional agents: tea core · Su Yunjin, matrine, thiamin, cyhalothrin, deltamethrin, biphenyl, and carbaryl salts.

If the condition is serious, it will be sprayed once again after 10~15 days.

Tea anthracnose

In the newly planted tea garden, select healthy seedlings with resistance. Balance fertilization to improve the disease resistance of tea trees, and timely cut off diseased branches.
