3、大豆病蟲害。以大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)食(shi)(shi)(shi)(shi)心(xin)蟲(chong)(chong)(chong)(chong)(chong)、大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)蚜蟲(chong)(chong)(chong)(chong)(chong)、大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)紅蜘蛛(zhu)、大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)根(gen)部(bu)(bu)病(bing)(bing)(bing)害(hai)為(wei)(wei)主的(de)(de)病(bing)(bing)(bing)蟲(chong)(chong)(chong)(chong)(chong)害(hai)總(zong)體(ti)為(wei)(wei)中等至中等偏重(zhong)(zhong)發(fa)(fa)生(sheng)(sheng)。去年(nian)(nian)大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)食(shi)(shi)(shi)(shi)心(xin)蟲(chong)(chong)(chong)(chong)(chong)蟲(chong)(chong)(chong)(chong)(chong)食(shi)(shi)(shi)(shi)率(lv)全省(sheng)平均為(wei)(wei)3.7%，較上(shang)(shang)年(nian)(nian)上(shang)(shang)升0.7個(ge)百分(fen)(fen)點，仍屬于(yu)(yu)(yu)(yu)較低年(nian)(nian)份(fen)，低于(yu)(yu)(yu)(yu)常(chang)年(nian)(nian)2.55個(ge)百分(fen)(fen)點。達到防治指標（蟲(chong)(chong)(chong)(chong)(chong)食(shi)(shi)(shi)(shi)率(lv)5%）的(de)(de)縣（市(shi)）占(zhan)(zhan)31.3%，高于(yu)(yu)(yu)(yu)上(shang)(shang)年(nian)(nian)9.6個(ge)百分(fen)(fen)點，蟲(chong)(chong)(chong)(chong)(chong)食(shi)(shi)(shi)(shi)率(lv)超過10%的(de)(de)縣（市(shi)）占(zhan)(zhan)9.0%，各地(di)(di)差(cha)異(yi)較上(shang)(shang)年(nian)(nian)更(geng)為(wei)(wei)顯著。若今年(nian)(nian)8月上(shang)(shang)中旬沒有(you)大(da)(da)(da)(da)(da)(da)(da)、暴雨天(tian)氣，預計部(bu)(bu)分(fen)(fen)地(di)(di)區(qu)大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)食(shi)(shi)(shi)(shi)心(xin)蟲(chong)(chong)(chong)(chong)(chong)可達到中等以上(shang)(shang)程(cheng)(cheng)(cheng)度(du)發(fa)(fa)生(sheng)(sheng)，發(fa)(fa)生(sheng)(sheng)期(qi)將(jiang)早于(yu)(yu)(yu)(yu)常(chang)年(nian)(nian)，發(fa)(fa)生(sheng)(sheng)區(qu)域(yu)以齊齊哈(ha)爾、黑(hei)河、綏化(hua)北部(bu)(bu)為(wei)(wei)主。東部(bu)(bu)地(di)(di)區(qu)的(de)(de)大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)蚜蟲(chong)(chong)(chong)(chong)(chong)及西、北部(bu)(bu)地(di)(di)區(qu)的(de)(de)大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)紅蜘蛛(zhu)發(fa)(fa)生(sheng)(sheng)期(qi)將(jiang)早于(yu)(yu)(yu)(yu)常(chang)年(nian)(nian)，發(fa)(fa)生(sheng)(sheng)程(cheng)(cheng)(cheng)度(du)將(jiang)達中等以上(shang)(shang)，重(zhong)(zhong)于(yu)(yu)(yu)(yu)常(chang)年(nian)(nian)。由于(yu)(yu)(yu)(yu)中南(nan)部(bu)(bu)大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)面積調(diao)減(jian)，重(zhong)(zhong)迎茬問(wen)題已得到根(gen)本性緩解，但北部(bu)(bu)地(di)(di)區(qu)由于(yu)(yu)(yu)(yu)缺少調(diao)茬作物，連作問(wen)題仍很嚴重(zhong)(zhong)，加(jia)之春季可能(neng)出(chu)現的(de)(de)局(ju)(ju)部(bu)(bu)干(gan)旱趨勢，將(jiang)加(jia)重(zhong)(zhong)苗(miao)期(qi)害(hai)蟲(chong)(chong)(chong)(chong)(chong)和(he)地(di)(di)下害(hai)蟲(chong)(chong)(chong)(chong)(chong)發(fa)(fa)生(sheng)(sheng)，根(gen)部(bu)(bu)病(bing)(bing)(bing)害(hai)與孢(bao)囊線蟲(chong)(chong)(chong)(chong)(chong)發(fa)(fa)生(sheng)(sheng)分(fen)(fen)布不均。局(ju)(ju)部(bu)(bu)澇洼地(di)(di)及重(zhong)(zhong)迎茬地(di)(di)塊的(de)(de)大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)菌核病(bing)(bing)(bing)會(hui)有(you)一(yi)定(ding)程(cheng)(cheng)(cheng)度(du)發(fa)(fa)生(sheng)(sheng)。大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)霜霉病(bing)(bing)(bing)、大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)褐紋病(bing)(bing)(bing)、大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)灰斑病(bing)(bing)(bing)等大(da)(da)(da)(da)(da)(da)(da)豆(dou)(dou)生(sheng)(sheng)長(chang)期(qi)葉(xie)部(bu)(bu)病(bing)(bing)(bing)害(hai)將(jiang)重(zhong)(zhong)于(yu)(yu)(yu)(yu)常(chang)年(nian)(nian)。
4、馬鈴薯與蔬菜病蟲害。預計為偏(pian)重(zhong)(zhong)發(fa)(fa)生。馬(ma)鈴(ling)(ling)薯(shu)晚疫病(bing)(bing)(bing)是影響全省馬(ma)鈴(ling)(ling)薯(shu)產量的(de)主(zhu)要病(bing)(bing)(bing)害(hai)(hai)(hai)，近(jin)年田間(jian)發(fa)(fa)病(bing)(bing)(bing)較(jiao)重(zhong)(zhong)，田間(jian)菌源(yuan)豐富，且(qie)生產中(zhong)(zhong)缺少抗病(bing)(bing)(bing)品種。由于夏(xia)季降(jiang)水集中(zhong)(zhong)期與馬(ma)鈴(ling)(ling)薯(shu)易(yi)感(gan)病(bing)(bing)(bing)的(de)花蕾期基本同(tong)步，根(gen)據氣候分析(xi)，預計馬(ma)鈴(ling)(ling)薯(shu)晚疫病(bing)(bing)(bing)仍(reng)將達到偏(pian)重(zhong)(zhong)至大發(fa)(fa)生程(cheng)度。同(tong)時馬(ma)鈴(ling)(ling)薯(shu)早疫病(bing)(bing)(bing)有加重(zhong)(zhong)的(de)趨(qu)勢。近(jin)兩(liang)年保護(hu)地蔬菜(cai)種植面積(ji)大幅增加，新增棚(peng)室(shi)管(guan)理(li)及病(bing)(bing)(bing)蟲(chong)(chong)害(hai)(hai)(hai)防控技(ji)術(shu)水平很難(nan)保證，春季保護(hu)地蔬菜(cai)病(bing)(bing)(bing)蟲(chong)(chong)害(hai)(hai)(hai)將偏(pian)重(zhong)(zhong)發(fa)(fa)生，缺素癥、生理(li)性病(bing)(bing)(bing)害(hai)(hai)(hai)、藥害(hai)(hai)(hai)等(deng)也(ye)將加重(zhong)(zhong)。預計溫室(shi)以(yi)番茄葉霉(mei)病(bing)(bing)(bing)、灰霉(mei)病(bing)(bing)(bing)、黃瓜角(jiao)斑(ban)病(bing)(bing)(bing)、菜(cai)豆疫病(bing)(bing)(bing)及大棚(peng)以(yi)霜霉(mei)病(bing)(bing)(bing)、晚疫病(bing)(bing)(bing)等(deng)病(bing)(bing)(bing)害(hai)(hai)(hai)為主(zhu)。棚(peng)室(shi)集中(zhong)(zhong)連片的(de)區(qu)域斑(ban)潛(qian)蠅、白粉虱等(deng)將偏(pian)重(zhong)(zhong)發(fa)(fa)生。露地蔬菜(cai)霜霉(mei)、病(bing)(bing)(bing)毒等(deng)病(bing)(bing)(bing)害(hai)(hai)(hai)及小菜(cai)蛾、甘藍夜盜(dao)、菜(cai)青蟲(chong)(chong)危害(hai)(hai)(hai)將重(zhong)(zhong)于常年。
5、小麥病害。預計(ji)中等(deng)偏(pian)輕至(zhi)中等(deng)發生。由(you)于(yu)冬季(ji)少雪，春季(ji)降水正(zheng)常(chang)，分布不均，小(xiao)麥(mai)腥、散黑穗病(bing)、根腐(fu)病(bing)部分區(qu)域會重(zhong)于(yu)常(chang)年，預計(ji)將達中等(deng)程度發生。夏季(ji)氣溫略高，后夏降水集中，局部地(di)塊小(xiao)麥(mai)赤霉病(bing)為害(hai)將加重(zhong)。
6、雜食性及突發性害蟲。總體為中等至中等偏重發生。苗(miao)期(qi)害蟲(chong)(chong)與(yu)地下(xia)害蟲(chong)(chong)：地老虎(hu)、蠐螬(cao)、螻蛄、金(jin)針蟲(chong)(chong)、大豆根(gen)潛蠅等(deng)地下(xia)害蟲(chong)(chong)越冬基數，全省平均平方米分(fen)別為(wei)0.6、0.5、0.76、0.7、1.64頭，均高于常年(nian)與(yu)上年(nian)。去年(nian)秋冬降(jiang)水少，農田底墑差，氣象預報(bao)春(chun)季氣溫正常略(lve)高，以二條葉甲、薊馬、跳(tiao)甲、黑絨金(jin)龜、斑須蝽為(wei)主的(de)苗(miao)期(qi)害蟲(chong)(chong)及以地老虎(hu)、蠐螬(cao)、金(jin)針蟲(chong)(chong)為(wei)主的(de)地下(xia)害蟲(chong)(chong)局(ju)部區域將重于常年(nian)。
遷飛性(xing)害蟲(chong)(chong)草(cao)地螟：根(gen)據全國(guo)測報網監測調查(cha)，國(guo)內(nei)草(cao)地螟越冬總蟲(chong)(chong)量(liang)是1996年(nian)以來(lai)第(di)三(san)個周(zhou)期(qi)(qi)內(nei)最低的年(nian)份。我(wo)省也未查(cha)到(dao)越冬蟲(chong)(chong)源(yuan)，同(tong)時(shi)根(gen)據草(cao)地螟發生周(zhou)期(qi)(qi)規律特點分析，預計(ji)今年(nian)草(cao)地螟大(da)面積重發生的可能(neng)不大(da)。
蝗蟲(chong)：2009年(nian)亞洲(zhou)飛蝗在我省(sheng)西部兩市三縣一場暴發后，由于實施了生態治理，近兩年(nian)均未(wei)發生。但并不(bu)排除今年(nian)個別(bie)葦塘濕地局(ju)部出現高(gao)蟲(chong)口密(mi)度的(de)可能。土蝗越冬卵量全省(sheng)平均每(mei)平方(fang)米(mi)2.1塊，較去(qu)年(nian)上升31.3%，西部常(chang)發區的(de)肇(zhao)東、林甸等地高(gao)于常(chang)年(nian)，預計土蝗在我省(sheng)中西部地區總體達(da)到中等以上程度發生，局(ju)部有高(gao)蟲(chong)口密(mi)度聚集危害的(de)可能。
遷飛性害(hai)(hai)蟲(chong)(chong)粘(zhan)蟲(chong)(chong)：近(jin)年(nian)二代粘(zhan)蟲(chong)(chong)在(zai)我(wo)省東部地(di)區(qu)發(fa)生(sheng)區(qu)域較廣(guang)，局部地(di)塊受害(hai)(hai)較重，且我(wo)省及江(jiang)淮等一代粘(zhan)蟲(chong)(chong)發(fa)生(sheng)區(qu)小麥播種面積呈回升趨(qu)勢(shi)，利于粘(zhan)蟲(chong)(chong)發(fa)生(sheng)危(wei)害(hai)(hai)。因此，粘(zhan)蟲(chong)(chong)在(zai)局部地(di)區(qu)玉(yu)米(mi)、小麥、城市草坪有造成危(wei)害(hai)(hai)的可(ke)能(neng)。
7、農田草害。據全省大部分地區監測，一年生雜草種子量，旱田(tian)平均(jun)每平方米為(wei)(wei)1680粒(li)，低于上(shang)年(nian)(nian)(nian)與常(chang)年(nian)(nian)(nian)；水(shui)田(tian)為(wei)(wei)1688.7粒(li)，高(gao)于上(shang)年(nian)(nian)(nian)，接近常(chang)年(nian)(nian)(nian)，但局部雜(za)(za)草種子量是常(chang)年(nian)(nian)(nian)的(de)(de)2倍(bei)以(yi)上(shang)。同時去年(nian)(nian)(nian)秋(qiu)冬(dong)以(yi)來降水(shui)少(shao)，有利于雜(za)(za)草種子成熟及(ji)多(duo)年(nian)(nian)(nian)生(sheng)(sheng)繁殖器(qi)官存活。今年(nian)(nian)(nian)春季(ji)大(da)(da)部分(fen)地(di)區干旱，預計旱田(tian)雜(za)(za)草出苗要(yao)晚，出草期將(jiang)(jiang)相對(dui)集中，封閉(bi)除草效果將(jiang)(jiang)受到影響，農田(tian)草荒將(jiang)(jiang)重于常(chang)年(nian)(nian)(nian)。旱田(tian)雜(za)(za)草以(yi)一(yi)年(nian)(nian)(nian)生(sheng)(sheng)的(de)(de)稗、藜、莧等(deng)為(wei)(wei)主要(yao)優勢(shi)種群(qun)，苣荬菜、鴨跖草、大(da)(da)（小(xiao)）薊、問荊仍為(wei)(wei)生(sheng)(sheng)產(chan)中難(nan)防(fang)雜(za)(za)草。水(shui)田(tian)野慈菇、澤瀉(xie)、雨久花等(deng)闊葉雜(za)(za)草優勢(shi)種群(qun)將(jiang)(jiang)更為(wei)(wei)突(tu)出。此外，豆改(gai)水(shui)、豆改(gai)玉的(de)(de)地(di)塊，仍將(jiang)(jiang)出現一(yi)定程度的(de)(de)殘(can)留藥害。
8、農田鼠害。近幾年全省大規模統一滅鼠，鼠密度已大幅度下降。全省平均百鋏（日）捕獲率為7.5%，比上年下降了1.4個百分點，比歷年均值13.2%下降了5.7個百分點。其中防治區內大部分控制在防治指標以下，但未防治區內平均鼠密度仍接近或超過10%，高出防治指標2倍以上，七臺河、泰來、肇東、密山等地分別達到21%、17%、15.2%、14.4%。秋冬季降水少，有利于害鼠越冬存活，且今年春季干旱，預計未進行大面積滅鼠的地區，早春作物與水稻苗床盜籽扒苗現象仍將較普遍，危害較重。
