| 摘 要： | 采用菌丝体生长速率抑制法和盆栽喷雾法测定特比萘酚和盐酸特比萘酚对16种植物病原菌的离体杀菌活性及其对9种植物病害的盆栽防效。结果表明，特比萘酚和盐酸特比萘酚对多种植物病原菌具有良好的杀菌活性，其中特比萘酚对8种真菌(山茶灰斑病菌、小麦赤霉病菌、玉蜀黍赤霉病菌、茄链格孢病菌、火龙果溃疡病菌、香蕉炭疽病菌、橡胶炭疽病菌和冬瓜炭疽病菌)的抑制活性较强，8种真菌的EC50为0.03～0.24 mg·L?1，盐酸特比萘酚对山茶灰斑病菌、小麦赤霉病菌、玉蜀黍赤霉病菌、茄链格孢病菌和火龙果溃疡病菌的抑制活性较强，EC50为0.03～0.22 mg·L?1。盆栽活体实验结果表明，特比萘酚和盐酸特比萘酚对多种农作物真菌病害具有良好的防治效果，在浓度为100 mg·L?1时均能100%控制豇豆白粉病；在浓度为400 mg·L?1时均能够有效抑制水稻纹枯病、小麦白粉病、黄瓜靶斑病、黄瓜白粉病和玉米大斑病，防效达到90%～100%。

| Abstract: | Sixteen species of plant pathogenic fungi and 9 plant fungal diseases were treated with fungicides terbinafine and terbinafine hydrochloride to observe their mycelium growth in vitro and in vivo control effect by pot-spraying, respectively. Results showed terbinafine and terbinafine hydrochloride had a good antifungal activity against many of the plant pathogenic fungi. Terbinafine showed a higher inhibitory effect against 8 species of the plant pathogenic fungi, i.e., Pestalotipsis guepinii, Fusarium graminearum, Gibberella zeae, Alternaria solan, Neoscytalidium dimidiatum, Fusarium oxysporum, Colletotrichum gloeosporioides and Colletotrichum orbiculare, and its EC50 values for these 8 fungal species were 0.03～0.24 mg·L?1. The terbinafine hydrochloride had a higher inhibitory effect against 5 fungal species, Pestalotipsis guepinii, Fusarium graminearum, Gibberella zeae, Alternaria solan and Neoscytalidium dimidiatum, and its EC50 values for these 5 fungal species were 0.03～0.22 mg·L?1. In vivo potted experiments showed that terbinafine and terbinafine hydrochloride effectively controlled many crop diseases. These two fungicides had a 100% control effect against cowpea powdery mildew (Podosphaera xanthii) when sprayed at a concentration of 100 mg·L?1, and a 90.00%～100.00% control of rice sheath blight (Rhizoctonia solani), wheat powdery mildew (Blumeria graminis), cucumber target leaf spot (Corynespora cassiicola), cucumber powdery mildew (Erysiphe cichoracearum), and northern corn leaf blight (Setosphaeria turcica) by when sprayed at 400 mg·L?1. |
