Greenhouse uses sticky insect board to improve vegetable quality
In the greenhouse vegetable shed, we saw dozens of yellow sticky insect boards evenly placed on the brackets above the vegetables, and the yellow boards were covered with small flying insects. The person in charge of the greenhouse vegetable planting professional cooperative said: "The 23 vegetable greenhouses here are hung with yellow sticky insect boards. The sticky insect boards are coated with glue. Pests such as aphids and whiteflies like yellow. As long as they are stuck, they will die. .”
"These yellow biological insect sticky boards are specially used to trap and kill various greenhouse pests. With the sticky insect boards, there is no need to apply pesticides to vegetables, and people can eat them with confidence." Mr. Zhang, the person in charge of the cooperative, said.
He also said that whitefly, aphids, scales, and African flies are the main pests of local fruits and vegetables. In the past, pesticides were mainly used to control pests. If the concentration of pesticides is low, the pests cannot be completely eliminated; if the concentration is high, not only will there be residues on the skin, but it will also affect the quality of fruits and vegetables, which cannot meet the standards of green and organic food. Since the use of Yunfei sticky boards, more than 400 adults can be trapped and killed with one board, and 500-800 larvae can be reduced for each adult. In addition to the yellow boards, technicians regularly bag the predatory mites, cut the gaps and fix them on the greenhouse, using the principle of biological natural enemies to hunt and kill whitefly, aphids and other pests.
