摘要
为更加有效地防治烟草青枯病,特选用新型生物药剂——农用链霉素泡腾片,以烟田常用药剂农用链霉素可湿性粉剂为对照,进行了田间小区药效的试验。结果表明,在发病初期施药后,农用链霉素泡腾片田间平均防治效果为29.77%;在与农用链霉素可湿性粉剂配合使用的情况下,最高防效可达62.0%,平均防效为56.82%。但对施药后的相对防效进行方差分析表明,其不同时期差异不甚明显。
In order to more efficiently control tobacco bacterial wilt, the control effect of new type of biological pesticide, effervescent troche of agricultural streptomycin （ETAS）, against tobacco bacterial wilt was tested with wettable powder of agricultural streptomycin （WPAS） as control. The results indicated that average control effect of ETAS applied in initial stage of tobacco bacterial wilt was 29.77%. The average control effect of mixed application of ASET and WPAS was 56.82%, and the highest control effect could reach to 62.0%. While the analysis of variance showed that difference in relative control effect after application of medicine was not clear among different periods.
