摘要
采用分组设计，共4个重复。实验重复进行，评价包括测定与对照相比菌丝生长的抑制作用。偶氮嘧菌酯和吡唑菌酯的EC50分别大于5和0.5µg mL -1时，为耐药菌株。对所有菌株的耐药性进行了验证。相比之下，偶氮嘧菌酯的抗性水平更高，即使在100µg mL -1时菌丝也能生长。
Sensibilidade de Alternaria alternata, agente causal da mancha marrom de alternária a fungicidas do grupo químico das estrobilurinas
block design was used, with four replications. The experiments were carried out in duplicates, and the evaluation consisted of determining inhibition of mycelial growth compared to the control. Isolates of A. alternata with EC50 for azoxystrobin and pyraclostrobin greater than 5 or 0.5 µg mL -1 , respectively, were considered resistant. The resistance of all the isolates evaluated was verified. Comparatively, the level of resistance was higher to azoxystrobin, with mycelial growth even at 100 µg mL -1 .
