根据抗药性治理的原则,针对我省棉蚜、棉铃虫抗药性实际状况,在全省范围内,制定和实施了一套适合我省特点的抗药性治理方案。在综合防治的前提下,具体和优化了化学防治,强调科学、合理使用农药。采用抗药性治理措施和综合防治措施后,示范区防治成本降低23%~33%,防治效果明显优于非示范区,经济效益十分显著。示范区用药次数和用量减少,对延缓棉铃虫抗药性的增长将起重要作用。
According to the principle of resistance management, in response to the actual situation of the cotton aphid and cotton bollworm resistance in our province, a suit of drug-resistant treatment program suitable for the province was formulated and implemented within the province. Under the premise of comprehensive prevention and control, concrete and optimized chemical control, emphasizing science and rational use of pesticides. After adopting the drug-resistant control measures and comprehensive prevention and control measures, the prevention and control costs in the demonstration area are reduced by 23% -33%, and the prevention and control effects are obviously better than those in the non-demonstration areas and the economic benefits are very significant. Demonstration area to reduce the frequency and dosage of medication, to delay the growth of resistance to bollworm will play an important role.
