河南省棉田害虫兼有南北两大棉区害虫的特点,种类多,防治难度大。由于多种害虫连年大发生,大量农药用于防治,特别是80年代以来大面积连续使用菊酯类农药,致使主要棉虫抗药性急剧增加,防效降低,生态环境恶化,严重威胁棉花生产。1986年以来,我们在河南省科委的支持下,组织了科研、教学及推广部门共15个单位参加的协作组,开展了棉花害虫综合治理的试验研究及示范。通过6年的协作研究,在害虫危害损失、防治指标和防治技术等方面取得较大进展,并在全省示范推广累计达200多万亩,取得了明显的经济效益、生态效益和社会效益。
The cotton pests in Henan Province have the characteristics of both north and south two cotton pests, variety, prevention and treatment is difficult. Due to the occurrence of many pests in successive years, a large number of pesticides are used for prevention and treatment. Especially since the 1980s, large areas of continuous use of pyrethroid pesticides have led to a sharp increase in drug resistance of major cotton insects, reduced control efficiency and deterioration of ecological environment, which threaten cotton production seriously. Since 1986, with the support of the Henan Provincial Science and Technology Commission, we have organized a collaborative group of 15 units in scientific research, teaching and promotion departments to carry out pilot studies and demonstration on the comprehensive management of cotton pests. Through 6 years of collaborative research, great progress has been made in pest damage loss, prevention and control indicators and prevention and treatment technologies. A total of more than 2 million mu have been demonstrated and popularized in the whole province and significant economic, ecological and social benefits have been achieved.
