2001年11月下旬以来,云南省大部分地区出现持续高温天气过程,冬季气温明显偏高,病虫害发生发展较快。根据全省农作物病虫监测网各站点监测:目前农作物斑潜蝇、大蒜叶枯病、农田杂草普遍严重发生。局部地区小麦条锈病、蚕豆锈病、油菜霜霉病、小麦白粉病、小麦蚜虫、小麦叶锈病、农田鼠害偏重发生。根据省气象台2002年长期天气趋势预测,春季气温正常偏高,雨量正常,春旱比常年轻,对斑潜蝇以及各种病害流行发展将比较有利,各地植保部门要加强监测,及时组织防治。一、当前主要病虫发生实况 Since late November 2001, there has been a continuous high-temperature weather process in most parts of Yunnan Province.
