The resistance of cotton aphid has become an urgent problem in cotton production. It is urgent to study and screen new types of cotton aphid and different application techniques. Cotton aphid is a kind of worldwide pest. When it is seriously damaged, it can cause the leaves to curl and the flower buds to fall off, which seriously affects the growth of cotton plants. In the field production practice, the control of cotton aphid has been dominated by chemical control, but with the large use of pesticides , cotton aphid not only produces higher levels of organophosphorus, carbamate and pyrethroids. resistance, and neonicotinoid pesticides such as imidacloprid, acetamiprid, also with varying degrees of resistance. The researchers of the Cotton Institute of the Chinese Academy of Agricultural Sciences selected six new medicinal agents. In 2016, they conducted field trials in Anyang County, Henan Province. They studied the effects of different new medicinal agents and different application methods on cotton aphid, in order to delay resistance and high efficiency. The scientific basis for the prevention of cotton aphid. The results showed that 3% thiamethoxam WG, 25% cyhalothrin acetamiprid EC and 48% butyl sulfa acetamiprid OF 3 new agents were effective in controlling cotton aphid by spraying with stems and leaves. The control effect was more than 95% one day after the drug, and the control effect increased with the increase of the drug dosage. However, the duration of the three potions on cotton aphid is not the same. 25% of thiamethoxam WG treated with 33.75-45 g/hm2 and 25% cyhalothrin acetamiprid EC 7.5-22.5 g/hm2 for more than 7 days, 48% butyl sulfoxide The treatment effect of 脒OF according to 120-180 g/hm2 is high and can be maintained for about 14 days. In the seed dressing treatment, 70% thiamethoxam WS is treated according to 315-420 g per 100 kg of seeds and 40% thiamethoxam pyraclostrobin wilsin FS is treated according to 300-400 g per 100 kg of seeds. The control effect of aphids is good, and the effective control period is more than 30 days after sowing, which can basically control the damage of aphids throughout the seedling stage. Compared with the two, 70% thiamethoxam WS has a slightly better control effect on cotton aphid than 40% thiamethoxam, pyraclostrobin and rust FS, and is investigated on the 30th day after sowing. The amount of sputum has reached 11,523, and the rate of coiled leaves is 100%. The dosage of the 315-420 g treatment area per 100 kg of seeds is still controlled below 1665, and the control effect is as high as 85.6%-92.4%. The period can be more than 40 days. 40% thiamethoxam·pyrazolone oxalate FS is a three-way compounding seed dressing agent for insecticides and fungicides . It not only has good insecticidal effect, but also effectively prevents seedling diseases. . The 2% imidacloprid slow-release granules have excellent control effect on cotton aphid by seedling treatment, and the field control effect and shelf-life period increase with the increase of drug dosage. The field is treated with 3 doses per 666.7 m2 1500-2500 g. The effect is high. Up to 30 days after sowing, the field control effect is still as high as 97.5%-98.9%, and the amount of cockroaches is controlled below 293 heads, which can basically control the occurrence of mites in the whole seedling stage. The researchers pointed out that the control of cotton aphid can use a variety of different agents, and according to different types of drugs, adopt the corresponding application methods such as seed dressing, ditch application or spraying; in order to prevent the cotton aphid resistance from rising faster, the field should pay attention to different Types of pesticides are rotated or alternated to avoid the use of the same agent alone.
