中文摘要 | 以長滿褐根病菌之樟樹枝條(10×1cm)作為追蹤標誌,評估三泰芬、待克利、撲克拉乳劑、撲克拉水基乳劑四種化學藥劑及土肉桂精油,進行稀釋1000倍土壤澆灌(20L m^(-2)),同時以水作為對照組,並與登記藥劑邁隆進行比較,於14d後對土壤5,30及50cm深度的褐根病菌之殘存影響。實驗結果指出土壤5,30及50cm深度的褐根病菌平均培養出的標誌數:施用三泰芬者為2.75,4.25及1.5支;待克利為3.5,2.75及1.25支;撲克拉乳劑者為3,3.25及2.0支;撲克拉水基乳劑為1.75,2.5及1.25支;土肉桂精油為1.75,2.5、1.75支;對照組水為2.75,1.25及2.25支;以邁隆進行燻蒸處理者褐根病菌平均養出的標誌數為0支。直接以褐根病追蹤標誌浸泡三泰芬、待克利、撲克拉乳劑、撲克拉水基乳劑及土肉桂精油1000倍稀釋液中,經過1,24及48h,褐根病菌均能在追蹤標誌中被分離出來。試驗結果顯示土壤藥劑澆灌方式對褐根病菌殘存之影響相當有限。 |
英文摘要 | Branch sections of camphor (Cinnamomum camphora) inoculated with tree brown rot disease Phellinus noxius were used as tracers for indicating the survival of P. noxius in soil, and hence for evaluating of the effect of chemical treatments. These indicators were buried at 5, 30, and 50 cm in depth of different experimental blocks of soil in the field, and 25% Prochloraz (E.C.), 25% Prochloraz (E.W.), 25% Triadimefon (W.P.), 24.9% Difenoconazole (E.C.), and the essential oil of Cinnamomum osmophloeum in 1000-fold dilutions were gently irrigated into different experimental blocks, with irrigation with water used as the control group. An experimental block of fumigation with the registered 98% Dazomet (G.R.) was applied for comparison. Branch tracers were collected, cleaned, and cultured with selective medium (MA+4) for P. noxius after 14 d. Re-isolation numbers of tracers with P. noxius in a total of 5 tracers buried at 5, 30, and 50 cm in depth of experimental blocks under each treatment were as follows: 3, 3.25, and 2 for Prochloraz (E.C.); 1.75, 2.5, and 1.25 for Prochloraz (E.W.); 2.75, 4.25, and 1.5 for Triadimefon; 3.5, 2.75, and 1.25 for Difenoconazole; 1.75, 2.5, and 1.75 for essential oil of C. osmophloeum; 2.75, 1.25, and 2.25 for the water control; and there was no re-isolation with Dazomet fumigation. Moreover, P. noxius could be re-isolated from all tracers after direct immersion for 1, 24, and 48 h in 1000-fold dilutions of Prochloraz (E.C.), Prochloraz (E.W.), Triadimefon, Difenoconazole, and the essential oil of C. osmophloeum. Results indicated that the tested chemicals have limited effects of inhibiting P. noxius in soil. |
