Resumo
It was evaluated the influence of nitrogen (N) levels in the severity of bean bacterial wilt, caused by Curtobacterium flaccumfaciens pv. flaccumfaciens, in the cultivars IAC Pyatã, IPR 88 – Uirapuru, and SCS 202 – Guará, under greenhouse conditions. The treatments consisted of the recommended level of N and rates 25% and 50% lower or higher than that, using urea as N source. The higher levels of N increased the progress of the bacterial wilt only in the cultivar IAC Carioca Pyatã. The N content in the plant aerial part did not interfere with the dry mass weight of any cultivars tested.
