摘  要：
噻唑锌是噻二唑类有机锌杀菌剂,对柑桔溃疡病有较好的防治效果。第一次药后13d和第二次药后20d调查结果表明,对柑桔叶片溃疡病,20%噻唑锌SC400～667ga.i./hm2的防治效果极显著高于77%氢氧化铜WP936ga.i./hm2,286ga.i./hm2处理防治效果与77%氢氧化铜WP936ga.i./hm2防治效果相当;对柑桔果实溃疡病,20%噻唑锌SC667ga.i./hm2的防治效果极显著高于77%氢氧化铜WP936ga.i./hm2,400ga.i./hm2的防治效果显著高于77%氢氧化铜WP936ga.i./hm2的防治效果,286ga.i./hm2防治效果与77%氢氧化铜WP936ga.i./hm2防治效果相当。生产上使用20%噻唑锌SC,推荐剂量为286～667ga.i./hm2,间隔10～15d,连续施药2～3次,对桔柑溃疡病有较好的防治效果。

摘  要：
Zn thiazole is a thiazole organic zinc fungicide with highly activity on citrus canker disease. Investigation data obtained at 13 days after applied first time and 20 days after second on the prevention and cure citrus canker disease of leaf indicated that the efficacy of Zn thiazole 20% SC applied at 400-667 g a.i./ha and Kocide 77% WP applied at 936 g a.i./ha differed at high significance level based on Duncan's New Multiple Range Test (DMRT). There wasn't significant difference on the efficacy between Zn thiazole 20% SC at 286 g a.i./ha and Kocide 77% WP at 936 g a.i./ha. On the prevention and cure citrus canker of fruit, the efficacy of Zn thiazole 20% SC at 667 g a.i./ha and 400 g a.i./ha were higher than that of Kocide 77% WP at 936 g a.i./ha at high significance and significance levels, respectively. Zn thiazole 20% SC applied at 286 g a.i./ha was equivalent to Kocide 77% WP applied at 936 g a.i./ha on control citrus canker of fruit. It is suggested that Zn thiazole 20% SC applied at recommended dosage 286-667 g a.i./ha and 2 to 3 times at 10-15 days interval would provide a good efficacy of canker disease.
