当前，南方早稻已进入生长后期，单季中晚稻大部也已栽插结束，水稻病虫陆续进入为害盛期。受多阵雨天气的影响，稻瘟病、稻飞虱以及稻螟虫等病虫害在部分地区发生严重。预计早稻后期穗颈瘟等在江南稻区将中等发生，稻飞虱等迁飞性害虫在江南及长江流域稻区将有较大虫源迁入。? At present, the early rice in the south has entered the later stage of growth. Most of the single-season late rice has also been planted and the pests and diseases of rice have entered the peak stage of succession. Affected by the rainy weather, pests such as rice blast, planthopper and rice stem borer have become serious in some areas. It is expected that panicle blast will occur moderately in the rice fields of southern China in the early rice period, and migratory pests such as planthoppers will migrate into larger areas in the southern part of Yangtze River and paddy areas of the Yangtze River. ?
