Mode of Spread and Survival for Bacterial Leaf Blight (BLB) of Rice

PrintPrintSend to friendSend to friend

The infected seeds as a source of inoculum may not be important since the bacteria decrease rapidly and die in the course of seed soaking. The pathogen survives in soil and in the infected stubbles and on collateral hosts like Leersia spp. Plantago najor, Paspalum dictum, and Cyanodon dactylon. The pathogen spreads through irrigation water in dry season and also through typhoons and rain storms.
