Pseudomonas syringae pv. actinidiae (Psa) causes bacterial canker disease in kiwifruit. Antibacterial activity of plant essential oils (PEOs) originating from 49 plant species were tested against Psa by a vapor diffusion and a liquid culture assays. The five PEOs from Pimenta racemosa, P. dioica, Melaleuca linariifolia, M. cajuputii, and Cinnamomum cassia efficiently inhibited Psa growth by eit...

Pseudomonas avellanae (Pav) has been reported as the causal agent of bacterial decline and bacterial canker of hazelnut in Italy and Greece, respectively. Both hazelnut diseases were reported to be similar in terms of symptoms, severity and persistence. In this study, we found that both symptomatic and asymptomatic trees in the field were colonized by Pav. Multilocus Sequence Typing (MLST) anal...

چکیده مرحله اپی فیتی باکتری pseudomonas syringae pv. syringae (pss) در شیوع و انتشار آن نقش اساسی دارد. این تحقیق با هدف تعیین جمعیت اپی فیتی باکتری pss روی تعدادی از علف های هرز باغات زردآلوی آلوده به بیماری شانکر باکتریایی در منطقه مرند انجام گرفت. در ماه های مهر و آبان از علف های هرز موجود نظیر پنیرک، تاج خروس، گل قاصد، پیچک، سلمه، قیاق و مرغ نمونه برداری شد. رقت های مختلف تا 7-10 از سوسپانس...

ABSTRACT Citrus bacterial canker disease has been introduced at least three times into Florida in the last 15 years and, despite federal and state quarantine and eradication efforts, continues to spread in Florida. Accurate, fast, and reliable detection of the causal agent is of great importance. However, citrus bacterial canker is caused by at least two groups of phylogenetically distinct Xant...
