目前我省旱澇(lao)不(bu)均，秋作物(wu)病蟲害(hai)發生形勢比較復(fu)雜，據各地植(zhi)保部(bu)門監(jian)測，各種病蟲害(hai)正(zheng)逐步進入發生高峰期，發生面積迅速擴大(da)，田(tian)間為害(hai)較重的主要病蟲有二(er)代玉米螟(ming)、薊馬(ma)、葉螨(man)、二(er)代棉鈴蟲、花生葉斑(ban)病、花生莖腐病等(deng)。

不完全統計，在(zai)前一階段(duan)的防治過程(cheng)中，全省共(gong)設立(li)秋(qiu)作物重大(da)病蟲監測(ce)基點942個，投入測(ce)報人員1194人，召開(kai)防治工作會(hui)224次(ci)(ci)，現場會(hui)84次(ci)(ci)，培訓干部2.7萬(wan)人次(ci)(ci)，農(nong)(nong)民(min)技術骨(gu)干93多萬(wan)人次(ci)(ci)，印發技術資料123萬(wan)份，進行電視宣傳155次(ci)(ci)，建立(li)綜合防治和專(zhuan)業化(hua)防治示范點179個，面積31.9萬(wan)畝，組建專(zhuan)業化(hua)防治隊1264個，農(nong)(nong)藥、藥械等防治物資的準(zhun)備也比較充裕(yu)。
目前我省大部分地區玉米、花生、大豆等作物長勢較好，部分地區較為干旱，旱澇不均情況明顯，病蟲害發生程度將會繼續加重。近期天氣對玉米褐斑病、玉米蚜、玉米頂腐病、花生白娟病、青枯病、彎孢霉葉斑病、花生葉斑病、莖腐病等病害發生非常有利；由于強對流天氣多，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風險較大。因此，各地植保部門要進一步加大監測力度，準確掌握田間病蟲害動態，及時發布病蟲害發生預報和防治警報，深入田間一線，指導農民適時開展科學防控，同時要加強安全用藥宣傳培訓，盡最大努力減少病蟲為害造成的損失，為奪取秋季糧食豐收做出貢獻。
