摘要

護粒丹(Hinodan)35%可濕性粉劑在不同地區對葉及穗稻熱病之防治效果最佳，也最穩定，對葉稻熱病之防治效果在對照區平均發病率爲44.9及41.5%時，其發病率各爲20.0及20.2%。對穗稻熱病之防治效果在對照區之平均罹病穗率爲14.8%時，其罹病穗率8.2%。護粒松(Hinosan)50%乳劑對葉稻熱病之防治效果不穩定，在發病嚴重的白河鎮其發病率爲50.1及54.2%，但對穗稻熱病仍有優良的防治效果。嘉賜米松(Kasumiron)2.1%粉劑可用於葉及穗稻熱病的防治，三賽唑(Beam)3%粒劑用於苗床可預防本田初期之葉稻病熱。

Among the fungicides tested at different locations, Hinodan 35% WP was the most effective and stable fungicide for controlling rice blast. The disease severity of Hinodan 35% WP tested plot were 20.0% or 20.2% while the disease severity of control plot were 44.9% or 41.5%, respectively. The percentage of disease panicle was 8.2% while the control plot was 14.8%. The effectiveness of Hinosan 50% EC on leaf blast control was not stable among the different locations tested. The disease seventies Hinosan 50% EC tested plots were 50.1% and 54.2% at Pai-ho area where the leaf blast was severe. However, it still gave an excellent panicle blast control at that area. Kasumiron 2.1% D. also could be applied for both leaf arid panicle blast control and Bain 3 % G. applied on the seedbed before transplanting to protect plants at early stage in the paddy field.
