摘　　要：为了评价植物生长调节剂在槟榔黄化病防控上的应用效果,选用5%胺鲜酯水剂、2%24-表芸·嘌呤水分散粒剂、0.136%赤·吲乙·芸苔可湿性粉剂、1.8%复硝酚钠水剂、6%寡糖·链蛋白可湿性粉剂和0.001%烯腺·羟烯腺水剂进行田间药效试验。结果表明:6种植物生长调节剂对槟榔黄化病均有一定的防控效果,其中6%寡糖·链蛋白可湿性粉剂防效最高,末次药后60d和150d的防控效果分别为60.23%和63.24%,与其他药剂处理差异显著,在槟榔生产中具有一定的推广价值。In order to evaluate the prevention and control effects of plant growth regulators on arecanut yellow leaf disease,a field experiment was carried out by using diethyl aminoethyl hexanoate 5%AS,24-brassinolide•benzylaminopurine 2%WG,gibberellin•heteroauxin•brassinolide 0.136%WP,sodium nitrophenolate 1.8%AS,oligosaccharins•plant activator protein 6%WP and oxyenadenine•enadenine 0.001%AS.The results showed that all the six plant growth regulators had certain control effect on arecanut yellow leaf disease.Among them,oligosaccharins•plant activator protein 6%WP had the best prevention and control effect,which was significantly different from other pharmaceutical treatments.The prevention and control effects were 60.23%and 63.24%at day 60 and day 150 after the last spray.Therefore,it has certain promotion value in arecanut production.
