INTEGRATED MANAGEMENT FOR THE BIPOLARIS LEAF BLIGHT AND FOOT AND ROOT ROT DISEASES OF WHEAT (Pages : 10 - 13)
M. MAHBUBUR RAHMAN, N. C. D. BARMA, P. K. MALAKER, M. R. KARIM AND A. A. KHANThe experiment was undertaken to find out an effective integrated approach in controlling Bipolaris leaf blight (BpLB) and Foot and root rot diseases of wheat under field condition in the cropping season 2007- 08. Sixteen treatments consisting of chemical fertilizer alone in combination with soil treatment (poultry refuse) and fungicide (Tilt 250EC) were considered for the management of Bipolaris leaf blight and Foot and root rot diseases of wheat caused by Bipolaris sorokiniana and Sclerotium rolfsii or Rhizoctonia solani respectively. Considerable differences were observed among the treatments regarding the disease severity, incidence, disease control and grain yield. Disease severity increased both at lower and higher doses of N that is at ‘0’ and ‘150’ kg N/ha, respectively. Disease severity was reduced significantly through the use of recommended chemical fertilizers (N100 P26 K50 S20 Bl). Addition of poultry refuse (1.5 tons/ha) and Tilt 250EC (0.5 ml/L) with chemical fertilizers further reduced disease severity resulting the highest grain yield (4956 kg/ha). This yield was higher over the farmers practice, N100 P26 K50 S20 + poultry refuse + Tilt 250EC and N50 P13 K25 S10 B1 + poultry refuse + Tilt 250EC, by 20%, 17% and 15% respectively. Download
