Abstract
1.Ledisan藥劑50ppm以上對洋菇腦菌病病原菌有良好之殺菌力。但滲透性實驗中則500ppm以上方有效。
2.Chloropicrin燻蒸試驗，20cc/m3對洋菇褐斑病病原菌有效用量增加至30cc/m3時，對Fusa-rium sp亦有抑制生長作用。但與處理溫度有關。
3.Basamid濃度125ppm以上，對腦菌病、褐斑病及Thielavia sp Myriococcum sp Chaet-omium sp.等病原菌有抑制生長作用，但在燻蒸效果試驗500ppm以上，僅對腦菌病及褐斑病病原菌有效。又土壤滲透性試驗而知500ppm以上，對病原菌菌絲生長有抑制作用500ppm以下之殘留毒性試驗，對洋菇菌絲生長無影響。
Several chemicals were tested to determine their value in controlling the cultivated mushroom diseases cause by fungi.
Ledisan at the concentration of above 50 ppm was very effective to control Truffle disease fungus (Diehliomyces microsporus), but it had not possed the good osmotic propriety. Basamid at the concentration of above 125 ppm had eradicative activity against Diehliomyces microsporus, Verticillium sp., Thielavia sp., Myriococcum sp. and Chaetomium sp. On the other hand, it only had the fumigating effect for the control of Truffle disease fungus and Brown Spot disease fungus (Diehliomyces microsp orus and Verticillium sp.). For the osmosis in soil, Basamid at the concentration of 500 ppm was effective against most of the cultivated mushroom disease fungus and according to its residual experiment, Basamid at the same concentration had not influented to the growth of hyphae of cultivated mushroom.
Chloropicrin was used as a fumigant at the dosage of 20cc/m3 could be considered the best fungicides to Brown Spot disease fungus and dosage of 30cc/m3 was very effective to Fusarium sp.
