據植(zhi)保部門發布的信息，當前華南(nan)、江南(nan)晚(wan)稻(dao)(dao)正處(chu)(chu)于分(fen)蘗(bo)期(qi)，江南(nan)一季中(zhong)(zhong)稻(dao)(dao)和東北單季稻(dao)(dao)處(chu)(chu)于灌漿乳熟期(qi)，長江中(zhong)(zhong)下游單季晚(wan)稻(dao)(dao)處(chu)(chu)于孕穗至(zhi)抽穗揚花期(qi)。田間病(bing)(bing)蟲害總體中(zhong)(zhong)等至(zhi)偏(pian)重發生(sheng)(sheng)，其中(zhong)(zhong)稻(dao)(dao)縱(zong)卷葉螟、二化(hua)螟、稻(dao)(dao)瘟病(bing)(bing)、紋枯(ku)病(bing)(bing)發生(sheng)(sheng)程度重于上年(nian)。水稻(dao)(dao)病(bing)(bing)蟲害防控用藥將(jiang)大有商機。
據國(guo)家氣象中(zhong)(zhong)心預(yu)(yu)報，近期江(jiang)(jiang)(jiang)(jiang)(jiang)南(nan)(nan)(nan)北(bei)部和長(chang)(chang)江(jiang)(jiang)(jiang)(jiang)(jiang)中(zhong)(zhong)游(you)降(jiang)雨偏(pian)(pian)多，適(shi)溫高濕的(de)田間小氣候對“兩遷”害(hai)(hai)蟲的(de)發生(sheng)(sheng)(sheng)(sheng)繁殖和稻(dao)(dao)(dao)瘟(wen)病(bing)、稻(dao)(dao)(dao)紋(wen)枯(ku)病(bing)等病(bing)害(hai)(hai)的(de)流行(xing)非常有利。結合當(dang)前病(bing)蟲害(hai)(hai)發生(sheng)(sheng)(sheng)(sheng)基(ji)數分析，8月下(xia)(xia)旬(xun)至9月中(zhong)(zhong)下(xia)(xia)旬(xun)，稻(dao)(dao)(dao)飛虱在(zai)(zai)(zai)華(hua)南(nan)(nan)(nan)、江(jiang)(jiang)(jiang)(jiang)(jiang)南(nan)(nan)(nan)、長(chang)(chang)江(jiang)(jiang)(jiang)(jiang)(jiang)中(zhong)(zhong)下(xia)(xia)游(you)稻(dao)(dao)(dao)區(qu)仍將(jiang)偏(pian)(pian)重(zhong)(zhong)(zhong)發生(sheng)(sheng)(sheng)(sheng)，局(ju)(ju)部大發生(sheng)(sheng)(sheng)(sheng);稻(dao)(dao)(dao)縱卷葉螟(ming)在(zai)(zai)(zai)江(jiang)(jiang)(jiang)(jiang)(jiang)南(nan)(nan)(nan)稻(dao)(dao)(dao)區(qu)偏(pian)(pian)重(zhong)(zhong)(zhong)發生(sheng)(sheng)(sheng)(sheng)，華(hua)南(nan)(nan)(nan)、長(chang)(chang)江(jiang)(jiang)(jiang)(jiang)(jiang)中(zhong)(zhong)下(xia)(xia)游(you)稻(dao)(dao)(dao)區(qu)總體中(zhong)(zhong)等，局(ju)(ju)部偏(pian)(pian)重(zhong)(zhong)(zhong)發生(sheng)(sheng)(sheng)(sheng);二化螟(ming)在(zai)(zai)(zai)江(jiang)(jiang)(jiang)(jiang)(jiang)南(nan)(nan)(nan)、長(chang)(chang)江(jiang)(jiang)(jiang)(jiang)(jiang)中(zhong)(zhong)下(xia)(xia)游(you)和江(jiang)(jiang)(jiang)(jiang)(jiang)淮稻(dao)(dao)(dao)區(qu)中(zhong)(zhong)等發生(sheng)(sheng)(sheng)(sheng)，局(ju)(ju)部偏(pian)(pian)重(zhong)(zhong)(zhong)發生(sheng)(sheng)(sheng)(sheng);稻(dao)(dao)(dao)瘟(wen)病(bing)在(zai)(zai)(zai)江(jiang)(jiang)(jiang)(jiang)(jiang)南(nan)(nan)(nan)、西南(nan)(nan)(nan)、長(chang)(chang)江(jiang)(jiang)(jiang)(jiang)(jiang)中(zhong)(zhong)下(xia)(xia)游(you)稻(dao)(dao)(dao)區(qu)將(jiang)中(zhong)(zhong)等發生(sheng)(sheng)(sheng)(sheng)，局(ju)(ju)部老病(bing)區(qu)及感(gan)病(bing)品種將(jiang)偏(pian)(pian)重(zhong)(zhong)(zhong)流行(xing);紋(wen)枯(ku)病(bing)在(zai)(zai)(zai)華(hua)南(nan)(nan)(nan)、江(jiang)(jiang)(jiang)(jiang)(jiang)南(nan)(nan)(nan)、長(chang)(chang)江(jiang)(jiang)(jiang)(jiang)(jiang)中(zhong)(zhong)下(xia)(xia)游(you)稻(dao)(dao)(dao)區(qu)將(jiang)偏(pian)(pian)重(zhong)(zhong)(zhong)至大發生(sheng)(sheng)(sheng)(sheng);稻(dao)(dao)(dao)曲病(bing)在(zai)(zai)(zai)江(jiang)(jiang)(jiang)(jiang)(jiang)南(nan)(nan)(nan)、長(chang)(chang)江(jiang)(jiang)(jiang)(jiang)(jiang)中(zhong)(zhong)下(xia)(xia)游(you)晚稻(dao)(dao)(dao)區(qu)將(jiang)中(zhong)(zhong)等發生(sheng)(sheng)(sheng)(sheng)，局(ju)(ju)部偏(pian)(pian)重(zhong)(zhong)(zhong)發生(sheng)(sheng)(sheng)(sheng)。為此(ci)，農業部門要求各地高度重(zhong)(zhong)(zhong)視，加強(qiang)監測預(yu)(yu)警，實施分類指導，采(cai)取有效(xiao)措施，減輕病(bing)蟲危害(hai)(hai)。
中晚稻(dao)“兩(liang)遷”害(hai)蟲及(ji)稻(dao)瘟病(bing)、稻(dao)紋枯病(bing)等病(bing)害(hai)的流行，水稻(dao)病(bing)蟲害(hai)防控用藥將大有(you)商機。就具體(ti)品種而言，氯蟲苯甲(jia)酰胺、氟苯蟲酰胺、茚蟲威、吡蚜酮、烯啶蟲胺、阿維(wei)菌素、甲(jia)氨基阿維(wei)菌素苯甲(jia)酸鹽、噻(sai)(sai)嗪酮、蘇云(yun)金桿(gan)菌、戊唑醇、井岡霉素、蠟質(zhi)芽孢(bao)桿(gan)菌、申嗪霉素、己唑醇、枯草芽孢(bao)桿(gan)菌、稻(dao)瘟靈(ling)、三(san)環(huan)唑、噻(sai)(sai)呋(fu)酰胺、丙環(huan)唑、苯醚(mi)甲(jia)環(huan)唑及(ji)其復配制(zhi)劑等將有(you)較多的表(biao)現機會。
