Integrated Management of Bacterial Leaf Blight {Xanthomonas oryzae pv. oryzae) in Rice under Sub-Tropics of Jammu

摘要

An integrated strategy for the management of BLB in rice was developed by altering the date of sowing, irrigation schedule, antibiotic spray and COC spray. The minimum disease severity of 15.44 per cent was recorded in streptomycin followed by copperoxychloride spray (20.56 per cent disease severity), in second date of transplanting (15th July) and second irrigation schedule (Water drained out after tillering stage) with the maximum of 11.33 tillers per hill, plant height of 123.33 cm, panicle length of 26.43 cm and yield of 3.92 t ha"1. However, the first date of transplanting (5th July) with first irrigation schedule (stagnant water) was least effective among all irrigation schedule and dates of transplanting with 7.33 tillers per hill and plantheight 106.00 cm and panicle length 19.33 cm along with 25.20 q ha"1 yield.
