    摘要:

    近年来玉米南方锈病在海南南繁基地普遍且偏重发生,已对玉米育种造成较大影响。本研究以控制玉米南方锈病发生、保护玉米育种健康发展为目标,对25%吡唑醚菌酯、19%丙环唑·嘧菌酯、40%丁香·戊唑醇、25%嘧菌酯和0.01%芸苔素内酯5种药剂的20个处理进行田间药剂防治试验,从中筛选出40%丁香·戊唑醇和0.01%芸苔素内酯混配组合以及25%吡唑醚菌酯和0.01%芸苔素内酯混配组合的2个药剂组合,喷施1次对南方锈病均有较好防治效果且防效持续时间长,防治效果达86.52%。研究结果表明:选择合适药剂组合并在关键时期施药能有效控制南方锈病暴发流行,消除南方锈病对南繁基地玉米品种选育造成的困扰。

    Abstract:

    Southern corn rust has been widespread and heavily emphasized in southern breeding bases in Hainan Province, which has caused a great damage to maize breeding in recent years. In this study, field treatment experiments in field were conducted on 20 treatments of 5 kinds of pesticides(25% pyrazoxystrobin, 19% propiconazoleazoxystrobin, 40% syringandrol-tebuconazole, 25% azoxystrobin and 0.01% brassinolide) to control the occurrence of southern corn rust. Two pesticide combinations were screened out from mixture both 40% syringandroltebuconazole and 0.01% brassinolide and mixture both 25% pyrazoxystrobin and 0.01% brassinolide. Spraying one time had a good effect on southern rust, with a control effect of 86.52% and long duration. The results showed that the use of appropriate combination of pesticides in the critical period can effectively control the outbreak of southern corn rust, and can eliminate the loss caused by southern corn rust on the maize breeding in southern breeding bases.
