Last Updated: 2024/11/22, The suitable temperature for the occurrence of cotton seedling aphid is 18 ℃ ~ 25 ℃, but the temperature rises rapidly after rain, which is very suitable for the occurrence of seedling aphid. 1. Agricultural control cotton to root out weeds, strengthen the management of water and fertilizer, promote the early emergence of cotton seedlings, pull out aphids with interseedling and fixed seedlings, and take them out of the field and burn them. 2. 10% imidacloprid wettable powder was used before 3 true leaves of seedlings, when the plant rate of rolled leaves reached 5%-10%, and after 4 true leaves reached 10%-20%.

The suitable temperature for the occurrence of cotton seedling aphid is 18 ℃ ~ 25 ℃, but the temperature rises rapidly after rain, which is very suitable for the occurrence of seedling aphid.

1. Agricultural control cotton

Root out weeds, strengthen the management of water and fertilizer, promote the early emergence of cotton seedlings, pull out aphids with interseedling and fixed seedlings, and take them out of the field and burn them.

2. Chemical control

Before 3 true leaves, when the plant rate of rolled leaves reached 5% to 10%, and after 4 true leaves reached 10% to 20%, 10% imidacloprid wettable powder 15 grams per mu was used to evenly spray 30 kg of water, or 10% acetamiprid EC 3000 times, or 20% acetamiprid wettable powder 1500000 times, or 20% thiocarbofuran EC 2000kg 4000 times. When spraying, we should focus on the heart leaves of cotton seedlings and pay attention to turning the sprinkler to spray to the back of the leaves.
