2021-03-18 08:59:18 來(lái)源：農(nóng)業(yè)農(nóng)村部新聞辦公室 閱讀量：13903 評(píng)論

　　【農(nóng)機(jī)網(wǎng) 熱點(diǎn)關(guān)注】 據(jù)農(nóng)業(yè)農(nóng)村部組織全國(guó)農(nóng)作物病蟲害測(cè)報(bào)網(wǎng)監(jiān)測(cè)，隨著氣溫回升，小麥條銹病擴(kuò)展速度顯著加快，草地貪夜蛾也進(jìn)入活躍期，重發(fā)流行態(tài)勢(shì)明顯。農(nóng)業(yè)農(nóng)村部提早印發(fā)《2021年全國(guó)“蟲口奪糧”保豐收行動(dòng)方案》，超前安排部署，要求各地加密監(jiān)測(cè)預(yù)警、強(qiáng)化技術(shù)指導(dǎo)、提早準(zhǔn)備物資、全力做好防控。
 
　　目前，小麥條銹病已在湖北、陜西、河南、甘肅、云南、四川、貴州、重慶等8個(gè)省份232個(gè)縣區(qū)發(fā)生215萬(wàn)畝，為近10年來(lái)第三重發(fā)年份。西北農(nóng)林科技大學(xué)康振生院士分析認(rèn)為，由于菌源充足、品種抗病性差、春季氣候條件適宜，雖然擴(kuò)展流行期比重發(fā)的去年有所推遲，但黃淮海等麥區(qū)春季大流行風(fēng)險(xiǎn)仍然較高。草地貪夜蛾已在云南、廣東、廣西等西南華南秋冬種玉米種植區(qū)累計(jì)發(fā)生164萬(wàn)畝，同比增加15%。中國(guó)農(nóng)科院吳孔明院士分析認(rèn)為，今年湄公河地區(qū)氣候條件利于草地貪夜蛾發(fā)生繁殖，后期境外遷入蟲源充足，境內(nèi)、境外蟲源疊加，草地貪夜蛾防控壓力將明顯大于去年。
 
　　針對(duì)今年病蟲害加重發(fā)生的態(tài)勢(shì)，農(nóng)業(yè)農(nóng)村部及時(shí)指導(dǎo)各地開(kāi)展應(yīng)急防治和統(tǒng)防統(tǒng)治。在小麥條銹病發(fā)生區(qū)提醒廣大農(nóng)民朋友做好藥劑預(yù)防，小麥返青后全面落實(shí)“帶藥偵查、打點(diǎn)保面”預(yù)防控制措施。在草地貪夜蛾發(fā)生區(qū)強(qiáng)化“三區(qū)四帶”布防，切實(shí)加大西南華南周年繁殖區(qū)冬春季防控和境外遷入蟲源撲殺，努力減輕當(dāng)?shù)匚：Γ瑝旱捅边w蟲源基數(shù)。
 
　　據(jù)悉，目前湖北、陜西、河南、四川等省已累計(jì)實(shí)施小麥條銹病防治面積277萬(wàn)畝次，云南、廣東、廣西等省份已累計(jì)實(shí)施草地貪夜蛾防治面積221萬(wàn)畝次。
