How to control tea plant pests without pollution? Please guide
Pollution-free pest control methods for tea plants:
I. Intercropping with other tree species
On the surrounding slopes and leftover corners of the tea garden, appropriately plant some tree species such as ginkgo and persimmon (planting Eucalyptus grandis is strictly prohibited) to improve the microclimate of the tea garden, increase biodiversity, and reduce the occurrence and damage of tea plant diseases and pests. Plant about 15 trees per mu, not exceeding 20 trees.
II. Install solar insect-killing lamps
Taking advantage of the phototaxis of pests, install solar insect-killing lamps to trap and kill adults of tea plant pests such as tea geometrid and tea tussock moth, reducing the number of eggs laid to lower the pest population base. One solar insect-killing lamp can control pests in about 50 mu of tea garden.
III. Insert yellow sticky traps
Taking advantage of the color taxis of pests, insert 20 yellow sticky traps per mu to trap and stick adults of winged aphids, black citrus whitefly and scale insects, small green leafhoppers and other pests. The lower edge of the yellow trap should be about 10 cm above the tea canopy, and the trap surface should be perpendicular to the walkway.
IV. Release predatory mites
Release predatory mites in the tea garden to feed on pest mites and control the damage. 10-15 days before releasing predatory mites, spray eco-friendly pesticides to lower the pest mite population base; release 20 bags of predatory mites per mu, and when releasing, cut open the predatory mite bags and hang them under the tea canopy. Do not apply insecticides or acaricides after releasing the mites.
V. Use sex pheromone traps
Use sex pheromones to trap and kill adults of tea plant pests such as tea geometrid, tea slug moth and tea tussock moth. Each set of sex pheromone controls pests in 1 mu of tea garden.
