評估非農業資材防治筊白銹病與胡麻葉枯病之效果

本研究主要目的為尋找與評估可防治茭白病害之非農藥資材，利用可濕性硫磺粉防治茭白銹病，試驗於定植茭白苗後，每7日噴施一次500倍80％可濕性硫磺粉防治效果良好，與石灰硫磺合劑、蘇打粉、碳酸氫鉀及無患子加植物油之防治方式在罹病程度與第一期筍產量有顯著性差異。胡麻葉枯病於培養皿內以非農藥資材試驗抑菌效果，本場生技研究室所開發之植物混合純露與大蒜浸出液效果最佳，但由於稀釋倍數過低與大蒜成本問題，未來仍需進行田間試驗效果與經濟效益評估。防治胡麻葉枯病部分，田間於一期筍收割後，採割除地上部方式，讓植株重新分蘗生長，新芽與新葉較不易受到胡麻葉枯病為害，且產量並無顯著差異。

The purpose of this study was to assess prevention disease by using non-chemical materials. The results indicated that 80% sulfur 500X could reduce rust significantly by sprayed sulfur every 7 days after planted water bamboo in the field. The results illustrated that 80% sulfur 500X has significantly efficacy compared with treatments of soda, sapindus extract oil and KHCO3 in the first phase of water bamboo harvest. For testing the non-chemical materials on inhibiting the pathogen causing brow spot in water bamboo, the plant extracts developed from Biotechnology Lab, TDARES under 5 to 50X dilution showed best results on inhibiting pathogen growth. After the first phase of water bamboo harvest, cut off above ground mining methods and plants to tiller from an old stump was less likely to suffer with Brown Spot and no reduction in yield of this model.
