防治稻飞虱要选准农药,方法对路,还要田内保持0.5—1寸深水。田内是否有水,对防治稻飞虱的效果影响很大。不论是喷雾方法,还是撒施方法,都是如此。在防治晚稻穗期稻飞虱时,很多田内不是因种红花无水,就是因天旱无水,这与防治晚稻穗期稻飞虱是一个很大的矛盾。为了解决这一矛盾,提高无水田防治稻飞虱的效果,去年我在吉水县枫江公社,用东方红——18机动喷 Control of planthoppers to be selected pesticides, on the road, but also to keep the field 0.5-1 inch deep water. Whether or not there is water in the field has a great impact on the prevention and control of planthoppers. This is true whether it is a spray method or a spreading method. When controlling planthoppers in the late rice stage, many fields are not caused by the lack of water of safflower or drought due to drought. This is a great contradiction with the prevention and control of rice planthoppers during the late rice stage. In order to solve this contradiction and improve the effect of non-paddy field in controlling planthoppers, last year I was in Fengshui Commune of Jishui County,
