Abstract
The influence of straw ashes on the weed control effect of some granular herbicides in rice was evaluated at the Chiayi Agricultural Experiment Station in the first crop of 1972. The incorporation of straw ashes into paddy soil reduced considerably the weed control effect of Saturn, TOK ,and MO-401 but not that of Machete. The application of straw ashes affected primarily the initial weed control effect of herbicides sensitive to straw ashes. The control of Echinochloa crusgalli was most severely affected by straw ashes which was followed by Cyperus difformis but Monochoria vag-inalis was not affected.
嘉義農業試驗分所於民國61年第1期作觀察稻草灰之施用，對若干推廣中稻田殺草劑治草效果之影響。初步結果顯示稻田施用稻草灰可減低掃丹、多谷、益歐-401等殺草劑之藥效，但馬上除之治草效果則極受影響。稻草灰以減低殺草劑初期治草效果為主，對殺草劑之殘效作用影響較少。主要雜草中稱草之防治最受稻草灰施用之影響，三角草次之，而鴨舌草則未受影響。
