Pharmacopoeia picking method: When cotton pods are severely harmed, 20% of cypermethrin or other pyrethrin EC can be used for 10-20 ml/mu, or 50% chlorinated ECG 20-30 ml/mu, or 50%. Cevaine wettable powder 30-50 grams / mu watered 40 kg alternating spray. If low-volume spray water is used for 10-15 kg, use of carbofuran, 3911, monocrotophos and other drama (high) toxic pesticides are strictly prohibited. The yellow plate entrapment method: Using the yellowing property of cotton aphids, yellow plates were trapped and killed outside the cotton field (on the field ridge). Method: Use 5030 cm yellow cardboard cardboard transparent plastic, coated with butter (oil or Vaseline, etc.), placed 30 cm above the plant. The yellow plate attracts more and more concentrated in the edge of the viscose board, the middle of the board is less, so the same area, the viscose board to grow a strip of insect trapping effect better than the square. Drop heart method: When cotton seedlings damage the leaf rolling rate of 5%, use omethoate diluted with 1:200 solution to deposit 2-3 drops of liquid drug on each cotton seedling growth point. Method: Remove the rotary knob of the backpack type hand pressure sprayer, wrap 3 layers with gauze, and unscrew the switch by one third after adding the medicine solution. The medicine droplets can flow out. Toxic soil fumigation method: In the middle and later stages of cotton growth, when the leaf rolling rate reaches 10% to 15%, use 80% dichlorvos EC 200ml/mu, dilute 4kg water, add 20kg sand, and mix well. In the early morning and late evening, ditch into the cotton fields. Urine washing mixture method: 500 grams of urea, washing powder (neutral) 200 grams, plus 100 kg of fresh water stirred into "urine washing mixture." After the detergent is completely dissolved, it is evenly sprayed on both sides of the leaf surface. Not only has good control effect on vegetable aphids. And it has the effect of foliar fertilization to promote growth. However, the "urine-washing agent" should be used immediately to prevent urea volatilization failure. Concealed application methods: Hemp seedlings occur in heavier cotton fields. Before pouring water, furrows are applied at 3% carbofuran 2-3 kg/mu, or 15% iron extinction grams (aldicarb) 350 g/mu. It is required that the ditch be separated from the cotton plant by 10-15 cm and the depth of the ditch is 10 cm. After the application, the soil shall be covered with water.

Applying the main stem method: when the seedlings of cotton seedlings occur at the seedling stage (when cotton seedlings damage the leaf rolling rate 5%), use 40% omethoate to mix the water with water 1:5-10 times and apply to the cotton stems. On one side of the phase, apply a length of 2-5 cm and do not ring.
