How to prevent and control rice bacterial leaf streak?
Rice bacterial leaf streak, or fine streak disease for short, is a bacterial disease caused by the genus Xanthomonas and is one of the domestic plant quarantine pests. High temperature and high humidity favor the onset of the disease; when this coincides with heavy rain, hail or flooding, causing numerous wounds on the leaves, the disease spreads extremely easily. Long-term deep water irrigation as well as excessive and late application of nitrogen fertilizer also make the disease more severe.
