采用室内生长速率法,研究戊唑醇和苯醚甲环唑混配对橡胶树炭疽病菌的增效作用。结果表明,不同配比的戊唑醇和苯醚甲环唑对橡胶炭疽病菌的联合作用表现为拮抗性、加和性及增效性3种不同作用,不同的炭疽病菌株对同种配比的药剂表现出不同的敏感性。戊唑醇与苯醚甲环唑以1∶3混配对胶孢炭疽菌RC178的增效最明显;1∶3和2∶5混配时,对尖孢炭疽菌RC169增效最佳;2∶5混配时,对胶孢炭疽菌RC227增效最优。
The indoor growth rate method was used to study the synergistic effect of tebuconazole and difenoconazole mixed with anthracnose on rubber tree. The results showed that the combined effects of tebuconazole and difenoconazole with different proportions on Colletotrichum gloeosporioides showed antagonistic, additive and synergistic effects. The effects of different anthracnose isolates on the same species Pharmaceutics show different sensitivities. The synergistic effect of tebuconazole and difenoconazole at 1: 3 on Colletotrichum gloeosporioides RC178 was the most obvious. The best synergistic effect on Acinetobacter sp. RC169 when mixed with 1: 3 and 2: 5 5, the synergistic effect on Colletotrichum germplasm RC227 is the best.
