玫瑰為國內重要內銷切花產業，然而在夏季的生產品質較差，為改善夏季玫瑰生產品質，分別施用生物性防治資材之菌液噴施，以本場研發的木黴菌TcTr-668 及芽孢桿菌Tcba05 兩種微生物菌液進行試驗，調查玫瑰切花品質及病害發生率。結果顯示，在施用微生物製劑的情況下可提高每月的平均切花量31.1%，提高每月的A 級品平均枝數46.4%、提高每月的B 級品平均枝數42.2%。在花頸部份1 月和7 月分別可提升17.6%和11.4%的花頸粗，在採後鮮重部份以1 月、5 月、7 月顯著高於對照之鮮重。106 年施用初期白粉病開始發生，多次使用微生物菌液，罹病度可降低至1%以下，對照慣行區則有相同的趨勢。107 年持續應用微生物菌液進行防治評估試驗，處理區前期白粉病罹病度達40%以上，但持續每周噴施情形下，至7 月份降低至10.57%；對照組前期施用化學藥劑，罹病度可控制在40%以下，但從4 月至6 月間罹病度均達30%以上，至7 月才降至17.78%，罹病度仍然高於處理區，顯示玫瑰田區持續施用微生物製劑進行白粉病防治，可以有效控制其發生與降低罹病度之功效。
Rose is an important domestic cut flower industry. However, the production quality in summer is poor, and the quality of summer rose has not been improved. Application the organic liquid Trichoderma TcTr-668 and Bacillus amyloliquefaciens Tcba05 developed in this field are used. The organic bacterial liquid was tested to investigate the quality of rose cut flowers and the incidence of diseases. The results showed that in the case of application of the microbial preparation, the average cut flower volume per month were increased by 31.1%, the average number of A-grade products per month were increased by 46.4%, and the average number of B-grade products per month were increased by 42.2%. In the flower neck, the neck and neck thickness of 17.6% and 11.4% were increased in January and July, respectively. The treatment fresh weight in the postharvest was significantly higher than the control in January, May and July. The experimental field was set up in Renai Township, Nantou County. At the beginning of the field trials in 2017, the microbial agent treatment area was used several times. The disease severity could be reduced to less than 1%, and the same trend is observed in the control area. In 2018, the microbial agent was continuously applied for the evaluation test. The disease severity of rose powdery mildew in the treatment area was over 40% in April, but after constantly used could to be lower to 10.57% in July, and the chemical application in the early stage of the control group. The disease severity was below 40%, but from April to June, the disease severity was more than 30%, and only fell into 17.78% in July. The control area disease severity still higher than the treatment area, indicating that the continuous application of microbial agent in the rose field for powdery mildew control and treatment can effectively control its occurrence and reduce the disease severity.
