摘  要：
在大田测定了25% 咪鲜胺与多菌灵混剂对芒果炭疽病的防治效果。25% 咪鲜胺与多菌灵的混合比例为1∶1,混剂的剂型为可湿性粉剂。试验结果表明:喷施25% 咪鲜胺·多菌灵混剂600、800和1 000倍稀释液的试验区,其芒果炭疽病病情指数没有显著性差异,但均显著低于空白对照区、喷施45% 咪鲜胺1 000倍稀释液和喷施50% 多菌灵可湿性粉剂500倍稀释液的试验区;而单独喷施45% 咪鲜胺1 000倍稀释液与喷施50% 多菌灵可湿性粉剂500倍稀释液的试验区的病情指数没有显著性差异。可见25% 咪鲜胺·多菌灵可湿性粉剂对芒果炭疽病具有良好的防效,而且其防治效果显著优于单独使用咪鲜胺或多菌灵。

摘  要：
Anthracnose (caused by Colletotrichum gloeosporioides Penz) is an important disease of mango. To study the controlling effect of the mixture of prochloraz and carbendazim (25% prochloraz and carbendazim in the proportion of 1 to 1) on mango anthracnose as compared to prochloraz and carberdazim alone, a field experiment was conducted in Danzhou, Hainan, in 2003. The results indicated that the trees sprayed with the mixture WP (diluted 600, 800, 1000 times) were lower in disease index than those in sprayed with 45% prochloraz EC (diluted 1000 times), 50% carbendazim WP (diluted 500 times) and the control. The trees sprayed with 45% prochloraz EC (diluted 1000 times) and 50% carbendazim WP (diluted 500 times) alone had no significant difference in control effect. The disease index of all the trees sprayed with the above chemicals were significantly lower than that of the water control, suggesting these chemicals had a good control effect on the anthracnose of mango. It was concluded that the mixture (WP) of 25% procchloraz and carbendazim had better effect against anthracnose of mango.
