安泰生防治芒果炭疽病效应

Effect of Antracol on Controlling of Mango Anthracnose

在芒果嫩叶及开花期间每隔 ７－ １０ ｄ喷 １次 １０００～２ ０００ ｕ ｇ／ｍＬ安泰生或 １０００ｕｇ／ｍＬ多菌灵杀菌剂可极显著地降低芒果叶片炭疽病的发生；果实中的潜伏侵染炭疽菌菌量亦显著地减少并且降低了贮藏期间果实炭疽病的严重程度。其中 ２ ０００ ｕｇ／ｍＬ安泰生效果最好，其防治叶片炭疽病效果达８１．５８％；采后果实炭疽病防效达６３．２１％。大田喷安泰生后还可适当提高果实产量和外观质量。

Antracol and carbendazim were applied to young leaves or flowers during leaf shooting and flowering stages to observe their effect on controlling of anthracnose of mangoes. Results showed that Antroacol and carbendazim sprayed at a respective rate of 1000 ug/mL-2000 ug/mL or 1000 ug/mL during leaf and flowering stages at 7-10 d intervals reduced significantly the occurrence of mango leaf anthracnose and the number of quiescent fungi in fruit which lessened the seventy of postharvest decay in fruits during storage. Antracol application at 2000 ug/mL showed the best effect among all the treatments: 81.58 % for controlling leaf anthracnose, and 63.21 % for controlling fruit anthracnose during storage. The yield and fruit appearance quality were improved by spraying of Antracol in the fields.
