Last Updated: 2024/11/22, Due to the recent low rainfall and high temperature, the number of cotton aphids increased sharply, which was significantly higher than that in the same period last year. If there is continuous high temperature and little rain, the number of cotton aphids will increase, which will lead to the occurrence of summer aphids. If the control is not timely, the cotton yield will be affected. Therefore, farmers should carry out prevention and control in time to achieve careful prevention and heavy prevention. 1. Chemical control. ① is sprayed with 1000-1500 times of acetamiprid or 10% imidacloprid EC, ② is sprayed with 1000-1500 times of 2.5% medium aphid trackless EC, and ③ is sprayed with 30% poison.

two。 Points for attention. ① cotton field should be widely used to control aphids, and the dosage should be increased in areas where aphids occur heavily, and the medicine should be used again every 3-4 days. Attention should be paid to make the liquid hit the back of the leaves when using the medicine, so that the efficacy can be brought into full play. When ② is used to control aphids, do not mix propranolol, because the plants with serious aphids are often small, the spraying is more, and the plant growth is more inhibited when the dosage is large.
