摘　　要：通过田间小区试验完成水直播条件下黑龙江省稻瘟病及纹枯病药剂防控效果分析,结果显示,防控叶瘟和穗颈瘟效果最好的药剂均是40%富士一号WP,相对防效分别为77.33%和89.98%,水稻产量为7.93、7.69 t/hm^(2);防控纹枯病效果最好的药剂是24%噻呋酰胺SC,相对防效为88.14%,水稻产量为7.98 t/hm^(2);兼防效果最好的药剂是27%戊唑·噻霉酮EW,水稻产量为7.36 t/hm^(2),较对照增产36.04%;在本试验条件下,水稻病害因子危害权重为穗颈瘟>叶瘟>纹枯病。Field experiments were conducted to study the control efficiencies of fungicides to rice blast and sheath blight under water direct seeding in Heilongjiang Province.The main results indicated as follow.The best fungicide of control leaf blast and neck blast were all 40%isoprothiolane WP,which the control effect were 77.33%and 89.98%,respectively.Furthermore,the yield of rice was 7.93 t/ha and 7.69 t/ha,respectively.The best fungicide of control sheath blight was 24%thifluzamide SC,which the control effect was 88.14%.Furthermore,the yield of rice was 7.98 t/ha.The best fungicide of concurrent control neck blast and sheath blight was 27%tebuconazole•benziothiazolinone,which the yield of rice was 7.36 t/ha,and the yield increased 36.04%than the control.The hazard weight of rice diseases may be neck blast>leaf blast>sheath blight under this test condition.
