Abstract
Effectiveness of some fungicides and antibiotics for the control of bacterial leaf blight in rice was tested at Adaptive Research Farm, Gujranwala, Pakistan and farmer’s field (tehsil Wazirabad, Gujranwala), during Kharif, 2006-2008. The Bordeaux mixture (2.5:2.5:300 i.e. 2.5 kg copper sulphate, 2.5 kg quick lime and 300 l/ha water), copper oxychloride 50% (1.25 kg/ha), oxytetracycline (0.75 l/ha) and streptomycin (0.50 kg/ha) alone and in combination with each other were tested and compared with untreated plot. Significantly low incidence of bacterial leaf blight was recorded when Bordeaux mixture alone (40.89 and 44.06 %) and in combination with oxytetracycline (38.67 and 42.67 %) and streptomycin (36.89 and 39.55 %) were applied as compared to control (56.00 and 63.45%) at the research farm and farmer’s field, respectively. These three treatments also gave maximum yield i.e 4.24, 4.27 and 4.34 tons per hectare at research farm and 3.45, 3.46 and 3.52 tons per hectare at farmer’s field, respectively. Bordeaux mixture alone gave maximum net return (Rs. 9375 /ha) followed by its combination with oxytetracycline (Rs. 8975/ha) and streptomycin (Rs. 8375 /ha). A loss of Rs.950, Rs.1550 and Rs.1700 per hectare occurred by the application of oxytetracycline streptomycin alone and their combination with each other, respectively, which is attributed to noneffectiveness of antibiotics and their high price. It is concluded that Bordeaux mixture proved more effective, broad spectrum and economical than copper oxychloride and antibiotics.
