全国农业技术推广中心发布《关于切实加强秋季农作物重大病虫害防控技术指导工作的通知》,预计水稻“两迁”害虫在南方中、晚稻区呈持续高发态势;稻瘟病在江南和华南局部晚稻区流行风险较高。江淮、黄淮、长江中下游及西南单季稻区,以稻飞虱为重点,对达到防治指标田块,及时选择高效低毒药剂(醚菊酯、吡蚜酮等)防治。如黄熟期田间无水时遇稻飞虱大发生,可选用敌敌畏毒土熏蒸。对以褐飞虱为主要种群的稻田,
The National Agricultural Technology Promotion Center released the Notice on Practically Strengthening the Guidance for Technical Guidance in the Prevention and Control of Major Insects and Pests in Crops in Autumn. It is estimated that pests in paddy fields will continue to increase in the southern and late rice regions. Rice blast is endemic in southern and southern China Late rice epidemic higher risk. Jianghuai, Huanghuai, the middle and lower reaches of the Yangtze River and single cropping areas in southwestern China focus on planthoppers, and the prevention and control index fields are selected, and the high and low toxicity pesticides (ettringithrin, pymetrozine, etc.) are timely prevented and controlled. Such as yellow ripening case of rice planthopper occurred in the field, the choice of dichlorvos toxic soil fumigation. To rice planthopper as the main population of rice fields,
