立枯病也是水稻秧田期主要病害，冷空气频繁侵袭，光照不足，气温偏低，雨水较多时容易引起发生。苗床除选用五氯硝基苯或敌克松做好消毒外，一般在落谷后覆土前或揭膜后喷雾进行预防。发病初期及时喷药防治。药剂可以选用瑞苗清或45%甲霜福每分秧田30～40克兑水10公斤喷施，病重时酌增用量，发病中心重点用药。秧田干旱，先灌足水后再用药，可以提高防效。药剂加入保禾丰、昂立帮、海藻酸叶面肥或生根剂喷施，可以促使秧苗变绿健壮。绛旓細鐥呯悊鎬绔嬫灟鐥鏄敱浜庡湡澹や腑鐥呭師鑿屼镜鏌撳紩鍙戠殑涓绫荤梾瀹筹紝琛ㄧ幇涓虹Ё鑻楁鏍熀閮ㄨ厫鐑傘佺煯鍖栥侀粍鍖栵紝鐢ㄦ墜鎷旀鏍椂鏍归儴鏄撴柇銆備袱绉嶇珛鏋梾瀵姘寸ɑ绉ц嫍鍗卞閮藉緢涓ラ噸锛屽鍙戠幇鏅氾紝闃叉不鏂规硶涓嶅綋锛岄槻娌讳笉鍙婃椂锛岄兘鏄撳紩璧锋暣浣撶Ё鑻楁浜° 闃叉不鏂规硶锛氱敤澶╄揪2116锛堝．鑻楃伒锛600鍊嶆恫鍔96%澶╄揪鎭堕湁鐏6000鍊嶆恫鍠锋磼銆
