Wilbrink' s-boric acid-cephalexin agar medium (WBC) was developed and tested for iso­ lating Xalllh omonas campeslris pv. IIndulosa, the causal agent of bacterial leaf streak of wheat or black chaff. from seed . WBC medium is Wilbrink's medium that has been modified by adding 0.75 gil of boric acid and 10 mg/l of cephalexin. Compared to the standard Wilbrink's medium, average plating efficiency...

Rice (Oryza sativa) cultivation represents a world laboratory for investigation into bacterial diseases of rice, in particular, and host-parasite interactions, in general, at the molecular, genetic, and genomic levels. The crop, in its various forms, has been under intense cultivation for more than 6,000 years, resulting in the selection of a wide variety of traits and germplasm (Khush, 1997). ...

Cassava brown streak disease (CBSD) was first observed on cassava (Manihot esculenta) in Rwanda in 2009. In 2014 eight major cassava-growing districts in the country were surveyed to determine the distribution and variability of symptom phenotypes associated with CBSD, and the genetic diversity of cassava brown streak viruses. Distribution of the CBSD symptom phenotypes and their combinations v...

Rice bacterial leaf streak (BLS) is a serious disease in rice leaves and can seriously affect the quality quantity of growth. Automatic estimation severity crucial requirement agricultural production. To address this, new method (termed BLSNet) was proposed for BLS lesion recognition segmentation based on UNet network semantic segmentation. An attention mechanism multi-scale extraction integrat...
