二、雙季晚稻病蟲發生趨勢分(fen)析

根據早稻(dao)(dao)(dao)(dao)、中(zhong)稻(dao)(dao)(dao)(dao)病(bing)(bing)蟲(chong)發(fa)(fa)生(sheng)(sheng)實況及(ji)病(bing)(bing)蟲(chong)源(yuan)殘(can)留基數，結合晚稻(dao)(dao)(dao)(dao)品(pin)種布局、未來的(de)氣(qi)候條(tiao)件(jian)和歷史資料(liao)綜合分(fen)析認為，預計晚季(ji)病(bing)(bing)蟲(chong)總體發(fa)(fa)生(sheng)(sheng)趨(qu)勢為偏重發(fa)(fa)生(sheng)(sheng)年份，發(fa)(fa)生(sheng)(sheng)面積達1000萬畝(mu)次(ci)。其中(zhong)稻(dao)(dao)(dao)(dao)飛虱、稻(dao)(dao)(dao)(dao)縱卷葉(xie)螟將偏重發(fa)(fa)生(sheng)(sheng)、局部大發(fa)(fa)生(sheng)(sheng)；螟蟲(chong)、紋枯病(bing)(bing)、細條(tiao)病(bing)(bing)、稻(dao)(dao)(dao)(dao)瘟病(bing)(bing)中(zhong)等發(fa)(fa)生(sheng)(sheng)，局部偏重。

1、稻(dao)飛虱(shi)：預計偏(pian)重(zhong)(zhong)發(fa)生，局部稻(dao)區(qu)大(da)發(fa)生，發(fa)生面(mian)積200萬畝(mu)次，較去年增加(jia)(jia)17%。其(qi)主要依(yi)據：一(yi)是(shi)(shi)單季(ji)稻(dao)稻(dao)飛虱(shi)偏(pian)重(zhong)(zhong)發(fa)生，殘留大(da)量蟲源(yuan)，并隨著單季(ji)稻(dao)的(de)收割逐漸(jian)遷(qian)入雙季(ji)晚稻(dao)為(wei)害。二是(shi)(shi)燈下(xia)誘測呈現蟲量持續遷(qian)入，且褐飛虱(shi)比(bi)例高。 據30個(ge)縣（市、區(qu)）統計，7月(yue)(yue)(yue)20日(ri)至8月(yue)(yue)(yue)20日(ri)燈下(xia)有(you)1-6次突(tu)增峰，平(ping)均2次；突(tu)增日(ri)誘蟲量500-5344頭(tou)，最多(duo)的(de)為(wei)安溪縣8月(yue)(yue)(yue)19日(ri)測報燈下(xia)21810頭(tou)；累(lei)計誘蟲量較去年同期增多(duo)占調查縣數的(de)60%，較常年增多(duo)的(de)占48%；褐飛虱(shi)比(bi)例大(da)部分達(da)60%以上。三(san)是(shi)(shi)當前雙季(ji)晚稻(dao)已發(fa)生30萬畝(mu)，田間蟲量大(da)，短(duan)翅(chi)型成蟲比(bi)例高。據30個(ge)縣（市、區(qu)）調查，一(yi)般百叢(cong)蟲量為(wei)100-800頭(tou)，高的(de)達(da)1400頭(tou)，其(qi)中(zhong)短(duan)翅(chi)型成蟲百叢(cong)蟲量為(wei)10-120頭(tou)，多(duo)的(de)達(da)180頭(tou)。四是(shi)(shi)氣候預報9月(yue)(yue)(yue)份臺風影響(xiang)及多(duo)雷陣雨(yu)天氣，有(you)利于異地蟲源(yuan)的(de)回(hui)遷(qian)而加(jia)(jia)重(zhong)(zhong)為(wei)害。

2、稻縱卷(juan)葉(xie)(xie)螟：預(yu)計中等偏(pian)重發(fa)(fa)生(sheng)(sheng)(sheng)，局部大(da)(da)發(fa)(fa)生(sheng)(sheng)(sheng)。發(fa)(fa)生(sheng)(sheng)(sheng)面積180萬畝次，較去年增(zeng)加(jia)(jia)20%。其主(zhu)要依據(ju)：一(yi)是田間(jian)蟲口殘留(liu)量(liang)較大(da)(da)。據(ju)各地(di)監測點近期單(dan)季稻田間(jian)趕蛾(e)，一(yi)般(ban)田間(jian)蛾(e)量(liang)達1000-2000頭，高的(de)達6000-10000頭。隨著單(dan)季稻的(de)收割卷(juan)葉(xie)(xie)螟蛾(e)將大(da)(da)量(liang)遷入(ru)雙(shuang)晚田加(jia)(jia)重為害；二是目前雙(shuang)季晚稻卷(juan)葉(xie)(xie)螟全省已發(fa)(fa)生(sheng)(sheng)(sheng)35萬畝；較去年同期增(zeng)加(jia)(jia)20%。三是9月份(fen)的(de)臺風雨氣候(hou)極(ji)有利該蟲產卵孵(fu)化、幼(you)蟲成活為害和(he)異地(di)蟲源的(de)遷入(ru)補充為害，近年來晚季第七代在福(fu)州(zhou)以南(nan)沿海稻區發(fa)(fa)生(sheng)(sheng)(sheng)較重。

3、螟(ming)蟲：預計(ji)(ji)四代三(san)(san)化(hua)螟(ming)為中等發(fa)生(sheng)，發(fa)生(sheng)面(mian)積(ji)60萬(wan)(wan)畝次(ci)；二化(hua)螟(ming)在沿海稻區(qu)偏重發(fa)生(sheng)，發(fa)生(sheng)面(mian)積(ji)130萬(wan)(wan)畝次(ci)，與去年相當。據30個縣（市、區(qu)）統(tong)計(ji)(ji)，第(di)三(san)(san)代三(san)(san)化(hua)螟(ming)已(yi)發(fa)生(sheng)20萬(wan)(wan)畝次(ci)，較去年減少30%，第(di)三(san)(san)代畝蟲量(liang)一般在120～1200頭，枯(ku)心(xin)率一般的0.1～2.0％。

4、稻(dao)瘟(wen)(wen)(wen)(wen)病(bing)：全(quan)省(sheng)(sheng)雙季(ji)(ji)晚稻(dao)葉瘟(wen)(wen)(wen)(wen)輕發(fa)(fa)(fa)生，預(yu)計穗(sui)瘟(wen)(wen)(wen)(wen)中等發(fa)(fa)(fa)生,山區(qu)(qu)、半山區(qu)(qu)、老病(bing)區(qu)(qu)部分品(pin)種(zhong)偏(pian)重(zhong)(zhong)發(fa)(fa)(fa)生，發(fa)(fa)(fa)生面積為60萬(wan)畝。主(zhu)要原因:一是(shi)(shi)當(dang)前(qian)(qian)全(quan)省(sheng)(sheng)雙季(ji)(ji)晚稻(dao)葉瘟(wen)(wen)(wen)(wen)已(yi)發(fa)(fa)(fa)生7萬(wan)畝，較去年(nian)同期(qi)相當(dang)；二是(shi)(shi)我(wo)省(sheng)(sheng)晚季(ji)(ji)主(zhu)栽品(pin)種(zhong)（組合）多數(shu)已(yi)種(zhong)植多年(nian)，抗(kang)病(bing)性(xing)減退，優質稻(dao)所占比例逐年(nian)加大(da)，抗(kang)病(bing)性(xing)差；三是(shi)(shi)當(dang)前(qian)(qian)氣(qi)候(hou)為時(shi)晴時(shi)雨(yu)，田間濕度大(da)，田間菌源充足，極有利葉瘟(wen)(wen)(wen)(wen)的發(fa)(fa)(fa)生蔓延，且(qie)破口抽穗(sui)期(qi)易遇(yu)秋淋雨(yu)，山區(qu)(qu)、半山區(qu)(qu)多雷陣雨(yu)，霧大(da)露(lu)重(zhong)(zhong)，如再(zai)遇(yu)秋寒天氣(qi)，穗(sui)瘟(wen)(wen)(wen)(wen)就有重(zhong)(zhong)發(fa)(fa)(fa)的趨勢。

5、稻(dao)紋枯病(bing)：預計偏(pian)重發生(sheng)，發生(sheng)面積180萬畝。為常發性病(bing)害，近期多(duo)雷陣雨和臺風天氣，適溫高濕(shi)，田間(jian)病(bing)情發展較(jiao)(jiao)快。據30個縣(xian)（市、區）統計，紋枯病(bing)已發生(sheng)20萬畝，較(jiao)(jiao)去年(nian)同期增加11%。

6、細菌性條斑病(bing)：預計細條病(bing)中等發(fa)(fa)(fa)生(sheng)，發(fa)(fa)(fa)生(sheng)面積70萬(wan)畝(mu)。目(mu)前全省已發(fa)(fa)(fa)生(sheng)7萬(wan)畝(mu)，部分稻區近(jin)期(qi)發(fa)(fa)(fa)展(zhan)蔓延較快。由于今(jin)年的多臺風雨(yu)氣候(hou)，近(jin)期(qi)細條病(bing)將擴展(zhan)較快，如(ru)果9月(yue)份有(you)臺風登陸(lu)或影響我省，細條病(bing)在沿海、沿江、低洼受淹稻區就有(you)流(liu)行的可能。

四、晚季(ji)病蟲害(hai)防治措施(shi)

要根(gen)據當地(di)病蟲(chong)(chong)害(hai)實情，明確各自主(zhu)攻對(dui)象(xiang)(xiang)，切實打(da)好關鍵時(shi)(shi)期病蟲(chong)(chong)防(fang)(fang)(fang)(fang)治(zhi)(zhi)戰(zhan)役。雙季(ji)晚(wan)稻(dao)(dao)(dao)、瓜(gua)后(hou)稻(dao)(dao)(dao)中后(hou)期病蟲(chong)(chong)主(zhu)要以螟(ming)蟲(chong)(chong)、稻(dao)(dao)(dao)飛虱、稻(dao)(dao)(dao)縱(zong)卷(juan)葉螟(ming)、稻(dao)(dao)(dao)穗(sui)瘟(wen)、紋枯病、細條病為主(zhu)攻防(fang)(fang)(fang)(fang)治(zhi)(zhi)對(dui)象(xiang)(xiang)，同時(shi)(shi)抓好農區鼠害(hai)監測和統(tong)一防(fang)(fang)(fang)(fang)治(zhi)(zhi)工作(zuo)。在防(fang)(fang)(fang)(fang)治(zhi)(zhi)技(ji)術(shu)上(shang)，突出準確測報(bao)、達標防(fang)(fang)(fang)(fang)治(zhi)(zhi)、健壯栽(zai)培、保護(hu)天敵(di)、安全(quan)用(yong)(yong)(yong)藥和推廣關鍵防(fang)(fang)(fang)(fang)治(zhi)(zhi)技(ji)術(shu)。尤其是對(dui)螟(ming)蟲(chong)(chong)、穗(sui)頸(jing)瘟(wen)的防(fang)(fang)(fang)(fang)治(zhi)(zhi)，一定要堅持預防(fang)(fang)(fang)(fang)為主(zhu)，突出應急防(fang)(fang)(fang)(fang)治(zhi)(zhi)，在晚(wan)稻(dao)(dao)(dao)破口抽穗(sui)期，及(ji)時(shi)(shi)組織群眾施用(yong)(yong)(yong)對(dui)癥、高(gao)效、安全(quan)藥劑(ji)及(ji)時(shi)(shi)應急防(fang)(fang)(fang)(fang)治(zhi)(zhi)。防(fang)(fang)(fang)(fang)治(zhi)(zhi)穗(sui)頸(jing)瘟(wen)可(ke)選(xuan)用(yong)(yong)(yong)三環唑、克瘟(wen)散等；防(fang)(fang)(fang)(fang)治(zhi)(zhi)紋枯病可(ke)選(xuan)用(yong)(yong)(yong)井岡霉素(su)；防(fang)(fang)(fang)(fang)治(zhi)(zhi)二化螟(ming)、三化螟(ming)、稻(dao)(dao)(dao)縱(zong)卷(juan)葉螟(ming)可(ke)選(xuan)用(yong)(yong)(yong)氟蟲(chong)(chong)腈、虎蛙、殺蟲(chong)(chong)單、好勞力等；防(fang)(fang)(fang)(fang)治(zhi)(zhi)稻(dao)(dao)(dao)飛虱可(ke)選(xuan)用(yong)(yong)(yong)吡蟲(chong)(chong)啉(lin)、撲(pu)虱靈、啶蟲(chong)(chong)脒、氯噻啉(lin)等；防(fang)(fang)(fang)(fang)治(zhi)(zhi)細條病可(ke)選(xuan)用(yong)(yong)(yong)龍克菌、葉青雙等。
