摘　　要：为了给田间筛选出防治橡胶树白粉病的新药剂,对咪鲜胺、氟硅唑、十三吗啉、三唑酮、硫磺粉等5种杀菌剂在发病苗圃进行常规防治试验。结果表明:药后7天,95%硫磺粉可湿性粉剂最好,防效达到83.0%,与其他4种药剂相比有极显著的差异性;75%十三吗啉乳油次之,防效达到60.2%;40%氟硅唑乳油、15%三唑酮可湿性粉剂和45%咪鲜胺微乳剂的防效较差,防效均在50%以下。药后30天,防效最好的仍是95%硫磺粉粉剂,防效为84.1%,其次是75%十三吗啉乳油,防效为78.2%,40%氟硅唑乳油的防效为69.1%,3种药剂无极显著差异,防效最差的是45%咪鲜胺微乳剂为33.0%。初步结论表明,95%硫磺粉可湿性粉剂仍为苗圃防治橡胶树白粉病的较好药剂,75%十三吗啉乳油和40%氟硅唑乳油可进一步开发利用。To screen effective therapeutic agent, 5 fungicides, namely, prochloraz （45% ME）, flusilazole （40%EC）, tridemorph （75% EC）, triadimefon （15% WP） and sulfur （95% WP） controlling powdery mildew of rubber were conducted by using conventional method in rubber nursery. The preliminary results showed that： after application 7 days sulfur （95% WP） was the best with control effect 83%, had a significant difference compared with other 4 kinds of agents. Tridemorph （75% EC） was better with control effect 60.2%. Flusilazole （40% EC）,triadimefon （15% WP） and prochloraz （45% ME） were worse with control effect less than 50%. After application 30 days, sulfur （95% WP） was still the best with control effect 84.1%. Tridemorph （75% EC） was better with control effect 78.2%. Control effect of Flusilazole （40% EC） was 69.1%. There was no significant difference between the 3 agents. Prochloraz （45% ME） was the worst with control effect 33.0%. So, sulfur （95%WP） was still a significant therapeutic agent against powdery mildew of rubbe in rubber nursery. Tridemorph （75% EC） and flusilazole （40% EC） could be further development and utilization.
