我省雙季(ji)早稻(dao)種植(zhi)面積360.91萬(wan)畝(mu)，較(jiao)去年(nian)增加(jia)(jia)11.98萬(wan)畝(mu)，中(zhong)(zhong)稻(dao)計(ji)劃種植(zhi)面積473萬(wan)畝(mu)，較(jiao)去年(nian)略(lve)增。5月26日我站(zhan)在福州召開了早季(ji)中(zhong)(zhong)后(hou)期農作物主(zhu)要(yao)病蟲(chong)(chong)鼠害(hai)發生趨勢(shi)會商會，參加(jia)(jia)會議的有全省9個(ge)設區(qu)市及部(bu)分重點站(zhan)的植(zhi)保專家(jia)共50多人，會議根(gen)據(ju)今(jin)年(nian)我省種植(zhi)結構、當前(qian)各地(di)病蟲(chong)(chong)發生情況、結合(he)歷(li)史資(zi)料和未來氣候(hou)發展趨勢(shi)等因素綜(zong)合(he)分析，預計(ji)2009年(nian)雙季(ji)早稻(dao)及中(zhong)(zhong)稻(dao)主(zhu)要(yao)病蟲(chong)(chong)害(hai)總體為偏重發生，局部(bu)稻(dao)區(qu)的稻(dao)飛虱和稻(dao)縱卷(juan)葉螟仍(reng)有大發生可能。
1、稻飛虱：預計(ji)雙季早(zao)稻偏重(zhong)發(fa)生(sheng)(sheng)(sheng)，發(fa)生(sheng)(sheng)(sheng)面積(ji)200萬畝次。中稻偏重(zhong)局部大(da)發(fa)生(sheng)(sheng)(sheng)，預計(ji)發(fa)生(sheng)(sheng)(sheng)面積(ji)為600萬畝次。主(zhu)要(yao)依據：
（1）燈(deng)下(xia)始見略(lve)早(zao)，前期累計誘蟲量少，褐飛虱比(bi)例偏高(gao)。
全省大部分燈(deng)下3月(yue)中旬至4月(yue)下旬始見，較去(qu)(qu)年(nian)略早，但(dan)燈(deng)下累計誘(you)蟲量較去(qu)(qu)年(nian)同期(qi)偏少。據各監測(ce)(ce)點(dian)統計，截止5月(yue)15日(ri)，平均每個(ge)監測(ce)(ce)點(dian)誘(you)蟲129頭，較去(qu)(qu)年(nian)減少60%；褐飛虱占35%，較去(qu)(qu)年(nian)高一倍。
（2）遷入(ru)峰較去年、前(qian)年遲(chi)，近(jin)期遷入(ru)蟲(chong)量激增(zeng)。
由于今年(nian)(nian)(nian)(nian)雨季(ji)推遲，大(da)部分(fen)監測點5月(yue)15日(ri)前未出(chu)(chu)現(xian)(xian)遷(qian)(qian)入(ru)(ru)峰，較(jiao)去年(nian)(nian)(nian)(nian)5月(yue)初(chu)、前年(nian)(nian)(nian)(nian)4月(yue)底出(chu)(chu)現(xian)(xian)遷(qian)(qian)入(ru)(ru)峰遲半個(ge)月(yue)。至5月(yue)18日(ri)全(quan)省出(chu)(chu)現(xian)(xian)強降水，稻飛(fei)虱(shi)(shi)隨之大(da)量(liang)遷(qian)(qian)入(ru)(ru)，燈下出(chu)(chu)現(xian)(xian)第一(yi)個(ge)明顯(xian)的遷(qian)(qian)入(ru)(ru)峰。新羅區18、19、20日(ri)雁石點分(fen)別誘(you)飛(fei)虱(shi)(shi)19200、21832、27136頭，較(jiao)去年(nian)(nian)(nian)(nian)同期明顯(xian)偏多，僅次于2007大(da)發生(sheng)年(nian)(nian)(nian)(nian)；古田(tian)縣18-20日(ri)分(fen)別誘(you)蟲324、640、7616頭，較(jiao)去年(nian)(nian)(nian)(nian)、前年(nian)(nian)(nian)(nian)同期均明顯(xian)偏多；永(yong)安5月(yue)20-25日(ri)共誘(you)蟲1203頭。此次遷(qian)(qian)入(ru)(ru)蟲源多以白背飛(fei)虱(shi)(shi)為主，褐飛(fei)虱(shi)(shi)僅占總(zong)蟲量(liang)的3.3%。
（3）前(qian)期(qi)(qi)田(tian)(tian)間(jian)蟲(chong)(chong)(chong)(chong)量(liang)(liang)(liang)較低，但(dan)近期(qi)(qi)上升(sheng)(sheng)迅速(su)。據5月(yue)15日(ri)各監(jian)測點調(diao)查(cha)(cha)，平(ping)(ping)(ping)均百(bai)叢(cong)蟲(chong)(chong)(chong)(chong)量(liang)(liang)(liang)為40頭(tou)(tou)，與(yu)去年同期(qi)(qi)相(xiang)當(dang)，隨著5月(yue)18日(ri)稻(dao)飛虱的(de)大量(liang)(liang)(liang)遷入(ru)，田(tian)(tian)間(jian)蟲(chong)(chong)(chong)(chong)量(liang)(liang)(liang)迅速(su)上升(sheng)(sheng)。新羅(luo)區(qu)5月(yue)18—19日(ri)調(diao)查(cha)(cha)，早稻(dao)田(tian)(tian)間(jian)平(ping)(ping)(ping)均百(bai)叢(cong)蟲(chong)(chong)(chong)(chong)量(liang)(liang)(liang)560—1050頭(tou)(tou)，其中成(cheng)蟲(chong)(chong)(chong)(chong)170—530頭(tou)(tou)，明顯比去年同期(qi)(qi)蟲(chong)(chong)(chong)(chong)量(liang)(liang)(liang)多，中稻(dao)秧(yang)田(tian)(tian)每株成(cheng)蟲(chong)(chong)(chong)(chong)3—4頭(tou)(tou)，高的(de)8—12頭(tou)(tou)；詔安(an)縣(xian)(xian)5月(yue)26日(ri)田(tian)(tian)間(jian)調(diao)查(cha)(cha)平(ping)(ping)(ping)均百(bai)叢(cong)蟲(chong)(chong)(chong)(chong)量(liang)(liang)(liang)達(da)670頭(tou)(tou)，最高的(de)達(da)2360頭(tou)(tou)，是去年同期(qi)(qi)的(de)3-5倍(bei)，且出現褐飛虱短翅型雌成(cheng)蟲(chong)(chong)(chong)(chong)；云(yun)霄縣(xian)(xian)5月(yue)21日(ri)田(tian)(tian)間(jian)調(diao)查(cha)(cha)，平(ping)(ping)(ping)均百(bai)叢(cong)蟲(chong)(chong)(chong)(chong)量(liang)(liang)(liang)284頭(tou)(tou)；永定縣(xian)(xian)5月(yue)21日(ri)田(tian)(tian)間(jian)調(diao)查(cha)(cha)，平(ping)(ping)(ping)均百(bai)叢(cong)蟲(chong)(chong)(chong)(chong)量(liang)(liang)(liang)210頭(tou)(tou)；閩清縣(xian)(xian)5月(yue)21日(ri)田(tian)(tian)間(jian)調(diao)查(cha)(cha)，平(ping)(ping)(ping)均百(bai)叢(cong)蟲(chong)(chong)(chong)(chong)量(liang)(liang)(liang)195頭(tou)(tou)。
（4）異地蟲(chong)源量(liang)大(da)。據全國農技中(zhong)心情報，受降(jiang)雨偏多、境外蟲(chong)源不斷(duan)遷入(ru)的影響，5月份以(yi)來，西(xi)南(nan)和華(hua)南(nan)稻(dao)區稻(dao)飛虱燈下(xia)誘蟲(chong)明(ming)顯，部(bu)分稻(dao)區顯著(zhu)高于去年和大(da)發生的2007年，田(tian)間蟲(chong)口密度急劇上升，云南(nan)南(nan)部(bu)、廣西(xi)和廣東沿海已(yi)超過防治指標。一旦氣候適宜將(jiang)大(da)量(liang)遷入(ru)我(wo)省(sheng)，將(jiang)對我(wo)省(sheng)雙季(ji)早稻(dao)造成嚴重威脅(xie)。
（5）多(duo)臺(tai)風雨氣(qi)候利于外地蟲源遷(qian)(qian)入(ru)(ru)。據(ju)省氣(qi)象臺(tai)預報，今(jin)年雨季于5月(yue)中(zhong)旬中(zhong)期（偏遲）開(kai)始，預計(ji)于6月(yue)下(xia)旬中(zhong)后(hou)期（偏遲）結(jie)束，雨季降(jiang)水正常(chang)略偏多(duo)。預計(ji)今(jin)年將有8～10個臺(tai)風或熱帶風暴(bao)登陸或影響我(wo)省，較常(chang)年偏多(duo)，其中(zhong)7月(yue)以(yi)前(qian)有1-2個臺(tai)風。稻(dao)飛虱將隨著臺(tai)風及降(jiang)雨持(chi)續不(bu)斷地遷(qian)(qian)入(ru)(ru)，同時我(wo)省復雜的(de)稻(dao)作(zuo)類型為稻(dao)飛虱的(de)遷(qian)(qian)入(ru)(ru)和(he)繁殖創造了有利的(de)食料(liao)和(he)生存條件。
2、稻(dao)縱卷葉(xie)螟：預計雙(shuang)季早稻(dao)中(zhong)等(deng)局(ju)(ju)部偏重發生(sheng)，發生(sheng)面積150萬(wan)畝次。中(zhong)稻(dao)為偏重局(ju)(ju)部大發生(sheng)，預計發生(sheng)面積500萬(wan)畝次。
主要依據：至今(jin)未出(chu)現(xian)遷(qian)入(ru)(ru)峰，燈(deng)下(xia)及田(tian)間成(cheng)蟲(chong)量(liang)均(jun)較(jiao)少。截止5月15日各監測點調查統計，平均(jun)單燈(deng)累計誘蛾6頭，與去(qu)年同期(qi)相當，平均(jun)畝趕蛾量(liang)4頭，較(jiao)去(qu)年同期(qi)減少30%。目前田(tian)間幼(you)蟲(chong)量(liang)極少。但稻縱卷葉螟多(duo)隨5月下(xia)旬至6月中(zhong)旬的強降雨大(da)量(liang)遷(qian)入(ru)(ru)我省，在(zai)早稻后期(qi)造成(cheng)大(da)面(mian)積的為(wei)害。另據全國農技中(zhong)心情報，目前華南中(zhong)西部田(tian)間蟲(chong)卵量(liang)大(da)，具備了(le)一定(ding)的蟲(chong)源(yuan)條件(jian)。
3、螟蟲：預計(ji)二化螟在寧德市大部，福州、三(san)明、南平(ping)、龍巖市局部雙(shuang)(shuang)季早稻(dao)及早插中稻(dao)偏重發(fa)生，其余中等發(fa)生；三(san)化螟偏輕發(fa)生。預計(ji)雙(shuang)(shuang)季早季及中稻(dao)發(fa)生面積200萬(wan)畝(mu)次。主要依據：
（1）冬(dong)后殘(can)(can)(can)(can)蟲(chong)(chong)量(liang)南部偏(pian)低閩東閩西(xi)(xi)部偏(pian)高。據各監測點3月份的冬(dong)后調查，全省(sheng)二(er)化螟(ming)平(ping)均(jun)(jun)畝殘(can)(can)(can)(can)留蟲(chong)(chong)量(liang)為5414頭(tou)，較(jiao)去(qu)(qu)年(nian)(nian)減少(shao)13%，但(dan)閩東、閩西(xi)(xi)部二(er)化螟(ming)的殘(can)(can)(can)(can)留量(liang)仍偏(pian)高，如新羅(luo)區(qu)二(er)化螟(ming)平(ping)均(jun)(jun)畝殘(can)(can)(can)(can)蟲(chong)(chong)量(liang)1259頭(tou)，較(jiao)去(qu)(qu)年(nian)(nian)增加21%；永定縣(xian)二(er)化螟(ming)平(ping)均(jun)(jun)畝殘(can)(can)(can)(can)蟲(chong)(chong)量(liang)5550頭(tou)，是去(qu)(qu)年(nian)(nian)的5.7倍(bei)；古田縣(xian)平(ping)均(jun)(jun)畝殘(can)(can)(can)(can)留蟲(chong)(chong)量(liang)為5479頭(tou)，較(jiao)去(qu)(qu)年(nian)(nian)增加52%，是前三(san)年(nian)(nian)均(jun)(jun)值的1.45倍(bei)。三(san)化螟(ming)平(ping)均(jun)(jun)畝殘(can)(can)(can)(can)留蟲(chong)(chong)量(liang)179頭(tou)，較(jiao)去(qu)(qu)年(nian)(nian)增加7%。
（2）燈(deng)(deng)下(xia)(xia)(xia)始見(jian)早(zao)(zao)，發生期提早(zao)(zao)。由于2-4月(yue)份(fen)我省平均(jun)氣溫偏高5.3℃、0.3℃和(he)0.2℃，降水偏少83.5毫米(mi)、0.7毫米(mi)和(he)54.8毫米(mi)，有(you)利(li)冬(dong)后幼蟲(chong)的化蛹和(he)羽化，發生期較(jiao)去(qu)(qu)年(nian)偏早(zao)(zao)6-8天(tian)。新羅區2月(yue)24日燈(deng)(deng)下(xia)(xia)(xia)始見(jian)，比去(qu)(qu)年(nian)早(zao)(zao)20天(tian)，比前年(nian)早(zao)(zao)6天(tian)；古(gu)田縣(xian)(xian)3月(yue)20燈(deng)(deng)下(xia)(xia)(xia)始見(jian)，較(jiao)去(qu)(qu)年(nian)早(zao)(zao)18天(tian)；蕉城縣(xian)(xian)3月(yue)20日燈(deng)(deng)下(xia)(xia)(xia)始見(jian)，比去(qu)(qu)年(nian)早(zao)(zao)6天(tian)；周寧縣(xian)(xian)4月(yue)22日始見(jian)較(jiao)去(qu)(qu)年(nian)早(zao)(zao)8天(tian)。
（3）燈下(xia)一(yi)代誘蛾(e)(e)(e)量(liang)高，蛾(e)(e)(e)峰多。全省平均燈下(xia)誘蛾(e)(e)(e)量(liang)345頭(tou)，較去(qu)年(nian)(nian)(nian)同期多3%。蕉城縣(xian)4月(yue)12-14日出現(xian)蛾(e)(e)(e)高峰，3天(tian)燈下(xia)共誘蛾(e)(e)(e)124頭(tou)，4月(yue)11-23日燈下(xia)誘蛾(e)(e)(e)量(liang)連續處于較高水平，13天(tian)共誘蛾(e)(e)(e)量(liang)298頭(tou)；福鼎縣(xian)4月(yue)中旬誘蛾(e)(e)(e)1679頭(tou)，是(shi)去(qu)年(nian)(nian)(nian)的7.2倍，4月(yue)21～26日誘蛾(e)(e)(e)526頭(tou)，是(shi)去(qu)年(nian)(nian)(nian)0.9倍，4月(yue)份燈下(xia)出現(xian)多個峰次，峰值均為(wei)近(jin)年(nian)(nian)(nian)來最(zui)高；周寧(ning)縣(xian)至5月(yue)13日燈下(xia)累計誘蛾(e)(e)(e)327頭(tou)，為(wei)去(qu)年(nian)(nian)(nian)同期的9.34倍，常年(nian)(nian)(nian)的2.5倍，燈下(xia)已出現(xian)4個峰，主(zhu)峰日誘蛾(e)(e)(e)量(liang)為(wei)去(qu)年(nian)(nian)(nian)21.3倍，常年(nian)(nian)(nian)的6.78倍。
（4）當前(qian)田(tian)間危(wei)害程度較(jiao)(jiao)去年(nian)(nian)同(tong)(tong)期相(xiang)當。據截止5月15日各監測點不完全(quan)(quan)統計，全(quan)(quan)省已(yi)發生面積80萬畝次(ci)，與去年(nian)(nian)相(xiang)當。當前(qian)平均畝幼蟲(chong)量(liang)3200頭，較(jiao)(jiao)去年(nian)(nian)略減，與常年(nian)(nian)相(xiang)當；平均枯鞘率2.4%，與去年(nian)(nian)同(tong)(tong)期相(xiang)當。
4、稻(dao)(dao)(dao)瘟病(bing)(bing)：預計雙季早稻(dao)(dao)(dao)及中稻(dao)(dao)(dao)稻(dao)(dao)(dao)瘟病(bing)(bing)在局(ju)部地區的(de)感(gan)病(bing)(bing)品(pin)種偏(pian)重發生，發生面積80萬畝。主要(yao)依據：
據各監測點冬后對當地今年水稻主栽品種的種子進(jin)行(xing)稻(dao)(dao)(dao)瘟(wen)(wen)(wen)(wen)病(bing)(bing)(bing)帶菌率(lv)(lv)(lv)抽樣檢(jian)測，大(da)面(mian)(mian)積種(zhong)(zhong)(zhong)植的(de)(de)品種(zhong)(zhong)(zhong)均有不(bu)同程度(du)的(de)(de)帶菌，全省(sheng)平均帶菌率(lv)(lv)(lv)2.17%，個(ge)別品種(zhong)(zhong)(zhong)帶菌率(lv)(lv)(lv)高。目前個(ge)別感病(bing)(bing)(bing)品種(zhong)(zhong)(zhong)在局部稻(dao)(dao)(dao)區葉(xie)(xie)(xie)(xie)瘟(wen)(wen)(wen)(wen)已經(jing)發(fa)(fa)生(sheng)(sheng)，田(tian)(tian)間菌源大(da)量(liang)存在。仙游縣2月(yue)(yue)(yue)9日(ri)對今年主栽(zai)雜優(you)(you)稻(dao)(dao)(dao)種(zhong)(zhong)(zhong)特(te)優(you)(you)航(hang)2號(hao)、特(te)優(you)(you)63等13個(ge)品種(zhong)(zhong)(zhong)進(jin)行(xing)測定(ding)，稻(dao)(dao)(dao)瘟(wen)(wen)(wen)(wen)病(bing)(bing)(bing)平均帶菌率(lv)(lv)(lv)0.11%，比去年和往(wang)年略低，其中豐(feng)兩(liang)(liang)優(you)(you)1號(hao)、楊(yang)兩(liang)(liang)優(you)(you)6號(hao)和兩(liang)(liang)優(you)(you)航(hang)2號(hao)帶菌率(lv)(lv)(lv)較高。4月(yue)(yue)(yue)18-19日(ri)田(tian)(tian)間調查(cha)(cha)，早稻(dao)(dao)(dao)葉(xie)(xie)(xie)(xie)瘟(wen)(wen)(wen)(wen)在部分豐(feng)兩(liang)(liang)優(you)(you)1號(hao)田(tian)(tian)塊(kuai)(kuai)上發(fa)(fa)生(sheng)(sheng)嚴(yan)(yan)重(zhong)(zhong)(zhong)，已塌圈(quan)0.2畝，病(bing)(bing)(bing)田(tian)(tian)病(bing)(bing)(bing)株率(lv)(lv)(lv)平均為46.67%，病(bing)(bing)(bing)葉(xie)(xie)(xie)(xie)率(lv)(lv)(lv)25.93%，病(bing)(bing)(bing)指14.41，嚴(yan)(yan)重(zhong)(zhong)(zhong)病(bing)(bing)(bing)田(tian)(tian)病(bing)(bing)(bing)葉(xie)(xie)(xie)(xie)率(lv)(lv)(lv)達(da)100%，病(bing)(bing)(bing)株枯死；浦城(cheng)縣5月(yue)(yue)(yue)8日(ri)雙(shuang)(shuang)早田(tian)(tian)調查(cha)(cha)，田(tian)(tian)間已發(fa)(fa)生(sheng)(sheng)稻(dao)(dao)(dao)葉(xie)(xie)(xie)(xie)瘟(wen)(wen)(wen)(wen)，主要發(fa)(fa)病(bing)(bing)(bing)品種(zhong)(zhong)(zhong)為T優(you)(you)7889，一般發(fa)(fa)生(sheng)(sheng)田(tian)(tian)平均病(bing)(bing)(bing)叢(cong)(cong)(cong)率(lv)(lv)(lv)32%，病(bing)(bing)(bing)株率(lv)(lv)(lv)6.06%，病(bing)(bing)(bing)葉(xie)(xie)(xie)(xie)率(lv)(lv)(lv)4.03%；嚴(yan)(yan)重(zhong)(zhong)(zhong)田(tian)(tian)病(bing)(bing)(bing)叢(cong)(cong)(cong)率(lv)(lv)(lv)達(da)96%，病(bing)(bing)(bing)株率(lv)(lv)(lv)37.8%，病(bing)(bing)(bing)葉(xie)(xie)(xie)(xie)率(lv)(lv)(lv)達(da)19.81%；再生(sheng)(sheng)稻(dao)(dao)(dao)發(fa)(fa)病(bing)(bing)(bing)品種(zhong)(zhong)(zhong)為兩(liang)(liang)優(you)(you)培九，病(bing)(bing)(bing)株率(lv)(lv)(lv)17.95%，病(bing)(bing)(bing)葉(xie)(xie)(xie)(xie)率(lv)(lv)(lv)8.72%；順昌5月(yue)(yue)(yue)14日(ri)雙(shuang)(shuang)早田(tian)(tian)間調查(cha)(cha)，準兩(liang)(liang)優(you)(you)2號(hao)發(fa)(fa)現(xian)葉(xie)(xie)(xie)(xie)瘟(wen)(wen)(wen)(wen)，一般發(fa)(fa)生(sheng)(sheng)田(tian)(tian)平均病(bing)(bing)(bing)叢(cong)(cong)(cong)率(lv)(lv)(lv)41.2%，病(bing)(bing)(bing)株率(lv)(lv)(lv)22.5%，病(bing)(bing)(bing)葉(xie)(xie)(xie)(xie)率(lv)(lv)(lv)14.3%,病(bing)(bing)(bing)指3.6,嚴(yan)(yan)重(zhong)(zhong)(zhong)田(tian)(tian)塊(kuai)(kuai)病(bing)(bing)(bing)叢(cong)(cong)(cong)率(lv)(lv)(lv)達(da)85.5%，病(bing)(bing)(bing)株率(lv)(lv)(lv)76.5%，病(bing)(bing)(bing)葉(xie)(xie)(xie)(xie)率(lv)(lv)(lv)達(da)44.8%,病(bing)(bing)(bing)指21.2。我省(sheng)雙(shuang)(shuang)季(ji)(ji)早稻(dao)(dao)(dao)及中稻(dao)(dao)(dao)的(de)(de)分蘗期及破口抽穗期多處于多雨(yu)季(ji)(ji)節，為稻(dao)(dao)(dao)瘟(wen)(wen)(wen)(wen)病(bing)(bing)(bing)的(de)(de)嚴(yan)(yan)重(zhong)(zhong)(zhong)發(fa)(fa)生(sheng)(sheng)提(ti)供了有利的(de)(de)氣候條件(jian)。各地必須針(zhen)對部分感病(bing)(bing)(bing)品種(zhong)(zhong)(zhong)可能(neng)偏(pian)重(zhong)(zhong)(zhong)發(fa)(fa)生(sheng)(sheng)造成連片重(zhong)(zhong)(zhong)大(da)產量(liang)損失(shi)的(de)(de)可能(neng)性，嚴(yan)(yan)密監測，緊密追(zhui)蹤在雙(shuang)(shuang)季(ji)(ji)是(shi)稻(dao)(dao)(dao)已出現(xian)嚴(yan)(yan)重(zhong)(zhong)(zhong)葉(xie)(xie)(xie)(xie)瘟(wen)(wen)(wen)(wen)的(de)(de)品種(zhong)(zhong)(zhong)，嚴(yan)(yan)防出現(xian)大(da)面(mian)(mian)積產量(liang)損失(shi)的(de)(de)不(bu)利局面(mian)(mian)。
5、稻(dao)紋枯(ku)病：預計(ji)雙季早(zao)稻(dao)及(ji)中稻(dao)將(jiang)偏重發生(sheng)，發生(sheng)面積(ji)300萬(wan)畝。
據各監測點冬后調查，平(ping)均(jun)(jun)畝殘留菌核量11.5萬粒，較去(qu)年(nian)同期(qi)減少(shao)(shao)10%。由于4月(yue)份以來，氣溫偏高雨水(shui)偏少(shao)(shao)，大部分稻(dao)區紋(wen)枯(ku)(ku)病(bing)始見期(qi)偏遲(chi)，田間擴(kuo)展速度慢(man)，發生程度偏輕。目前全省發生5萬畝，較去(qu)年(nian)及常年(nian)偏少(shao)(shao)，平(ping)均(jun)(jun)叢病(bing)率(lv)2.29%，株病(bing)率(lv)0.37%，葉病(bing)率(lv)0.06%，均(jun)(jun)較去(qu)年(nian)偏輕。但隨著雨季(ji)的到(dao)來及水(shui)稻(dao)的封行， 5月(yue)下(xia)旬到(dao)6月(yue)上旬將進入(ru)紋(wen)枯(ku)(ku)病(bing)的水(shui)平(ping)擴(kuo)展高峰期(qi)，擴(kuo)展蔓(man)延速度加快(kuai)。
6、農田鼠害(hai)：預計(ji)局部偏重發生，發生面積200萬(wan)畝次。據全(quan)省各監(jian)測(ce)點(dian)調查1～5月份的(de)平均鼠密度(du)平均2.9%，較去年(nian)略增。
此外，水(shui)稻(dao)細(xi)條病、病毒病、稻(dao)曲(qu)病、稻(dao)桿潛蠅、稻(dao)粉虱等病蟲害將區域性(xing)重發，各地(di)也(ye)應加(jia)強(qiang)監測。
