recently, the weather has been dry with little rain, sufficient light, and suitable temperature, which is suitable for the growth of cotton. however, it is also conducive to the occurrence of cotton aphids. some cotton fields showed situations of excessive growth of cotton seedlings or heavy harm from aphids, and difficulties in prevention and control. experts from the institute of cotton, together with technicians from the nangong agricultural and rural bureau, visited the cotton fields in beihu, wangdaozhai, gaocun and other towns to conduct training and technical guidance on the growth of cotton seedlings and the occurrence of aphids.
green prevention and control techniques such as rotating the use of different types of pesticides and improving work modes were provided for cotton aphid control. a simplified management technique for chemical regulation based on seedling classification was proposed for cotton fields with different growth trends. the leaders of nangong agricultural and rural bureau asked the accompanying township technicians to do a good job of publicity in the form of radio, wechat group, etc., to transmit the management technology to the majority of cotton farmers and further improve the cotton field management level.
