近期我(wo)省出(chu)現了一次明顯降水，多數地(di)區墑情適宜(yi)，田(tian)間(jian)條件適合病(bing)(bing)(bing)蟲(chong)(chong)發生(sheng)(sheng)，秋作(zuo)物(wu)病(bing)(bing)(bing)蟲(chong)(chong)害已進入發生(sheng)(sheng)高峰期，發生(sheng)(sheng)面積迅速擴大，目前田(tian)間(jian)為害較(jiao)重的病(bing)(bing)(bing)蟲(chong)(chong)主要(yao)有二代玉米(mi)螟、三代粘蟲(chong)(chong)、三代棉鈴(ling)蟲(chong)(chong)、玉米(mi)褐斑(ban)病(bing)(bing)(bing)、花(hua)生(sheng)(sheng)葉斑(ban)病(bing)(bing)(bing)、花(hua)生(sheng)(sheng)莖腐病(bing)(bing)(bing)、花(hua)生(sheng)(sheng)白絹病(bing)(bing)(bing)等(deng)。

不完全統計，在前一階段的防治過程中，全省共設立秋作物重大病蟲監測基點909個，投入測報人員1171人，召開防治工作會283次，現場會142次，培訓干部4.0萬人次，農民技術骨干241多萬人次，印發技術資料182.9萬份，進行廣播宣傳235次，建立綜合防治和專業化防治示范點181個，核心區面積30.6萬畝，組建專業化防治隊1548個，農藥、藥械等防治物資的(de)準備也比較充裕。
由于近期我省大部地區出現降雨過程，田間高溫高濕，對玉米褐斑病、彎孢霉葉斑病、玉米南方銹病、玉米螟、玉米頂腐病、花生葉斑病、花生白娟病、花生莖腐病等病害發生為害非常有利；短時強降水等強對流天氣，導致三代粘蟲、棉鈴蟲、甜菜夜蛾等遷飛性、雜食性害蟲在局部地區暴發為害的風險增加；同時由于降雨分布不均，豫西北、豫西南等部分干旱地區玉米蚜、花生葉螨等刺吸性害蟲會在局部為害也有可能加重；因此，要求各級植保部門密切監測秋作物病蟲害發生動態，及時發布病蟲情報指導群眾防治，力爭將病蟲害造成的損失降到最低。
