【摘要】 [目的]明确4种药剂对赤霉病和白粉病的防治效果以及对产量的影响。[方法]试验于小麦破口前后分2次采取喷雾法进行田间药效试验。[结果]48%醚菌酯·戊唑醇SC、50%戊唑·多菌灵SC和40%戊唑·咪鲜胺EW对小麦白粉病的防效分别为100%、93.45%、88.7%,显著高于氰烯菌酯,4组处理对赤霉病的防效均处于90%左右,其中以50%戊唑·多菌灵SC防效最佳,达到92.27%,而48%醚菌酯·戊唑醇SC处理后的小麦增产最明显,增产24.16%。[结论]综合对白粉病、赤霉病的防效以及对产量的影响,建议田间采用48%醚菌酯·戊唑醇SC、50%戊唑·多菌灵SC分2次对小麦白粉病和赤霉病进行防治。更多还原

【Abstract】 [Aims]Ethermycin-tebuconazole, tebuconazole-carbendazim, amidazole-imidamide and cyanenide were the main bactericides in controlling Fusarium graminearum and Blumena graminis in recent years. This study aims to evaluate the control effects of these four pesticides above and influences on yield. [Methods]The field trials were carried out by spraying in two steps after wheat breaking. [Results]Ethermycin-tebuconazole 48% SC,tebuconazole-carbendazim 50% SC and amidazole-imidamide 40% EW displayed effect of 100, 93.45, 88.7% against B. graminis, respectively, which were significantly higher than cyanenide. In addition, the four fungicides showed effect of about 90% against F. graminearum and tebuconazole-carbendazim 50% SC indicated the highest control, which reached 92.27%. Besides, ethermycin-tebuconazole 48% SC brought a 24.16% increasing on yield, higher than the other groups. [Conclusions]Ethermycin-tebuconazole 48% SC and ebuconazole-carbendazim 50% SC are recommended to control the two diseases by two times applications.更多还原
