摘要
为筛选出有效防治水稻穗颈瘟的药剂,以感病品种糯稻99-25为试验对象,在黄海农场二生产区进行不同药剂防治水稻穗颈瘟的田间试验。结果表明,施药后各药剂均未对水稻产生明显药害。25%吡唑醚菌酯SC900ml/hm^2对水稻穗颈瘟防效最高,为83.25%;75%三环唑WP防效其次,为80.17%。因此,25%吡唑醚菌酯SC能有效防治水稻穗颈瘟的发生,可在水稻生产上推广使用。
The study aims to screen out efficient fungicides for controlling rice panicleblast.With Glutinous Rice 99-25 as tested material,the field controlling test with different fungicides was carried out in second production area,Huanghai farm.No obvious phytotoxicity was observed after bactericide application.25%Pyraclostrobin SC 900ml/hm^2 showed the best control efficacy and reached 83.25%,followed by the 75%tricyclazole WP and control efficacy was 80.17%.25%Pyraclostrobin SC is the effective fungicide to control rice panicle blast and can be popularized for filed control.
