摘要:

为了给田间筛选出防治橡胶树棒孢霉落叶病的高效药剂,对甲基硫菌灵、咪鲜胺锰盐、多菌灵、百菌清、咪鲜胺等5种杀菌剂在发病苗圃进行常规防治试验。结果表明:25%咪鲜胺乳油最好,2000倍液药后28天防效达到82.99%;75%百菌清可湿性粉剂次之,2000倍液药后28天防效达到78.20%;70%甲基硫菌灵可湿性粉剂、50%咪鲜胺锰盐可湿性粉剂、50%多菌灵可湿性粉剂的防效较差,参试浓度防效均在50%以下。初步结论表明,25%咪鲜胺乳油和75%百菌清可湿性粉剂为苗圃防治橡胶树棒孢霉落叶病的较好药剂,推荐使用浓度为2000倍。

Abstract:

To screen effective therapeuticagent, 5 fungicides, namely, thiophanate methyl (70% WP), prochloraz manganese (50% WP), carbendazim (50% WP), chlorothalonil (75% WP) and prochloraz (25% EC) controlling Corynespora leaf fall disease (CLFD) of Hevea rubber were conducted by using conventional method in rubber nursery. The preliminary results showed that prochloraz (25% EC) diluted 2000 times was best with control effect 82.99% after application 28 days. Chlorothalonil (75% WP) was better with control effect 78.20% at the same condition. Thiophanate methyl (70% WP), prochloraz manganese (50% WP) and carbendazim (50% WP) were worse with control effect less than 50% in conditions of test. So, prochloraz (25% EC) and chlorothalonil (75% WP) were preferable therapeuticagents against CLFD in rubber nursery with diluted 2000 times.
