Success of Bio Products against Bacterial Leaf Blight Disease of Rice caused by Xanthomonas oryzae pv. oryzae

Abstract:

Bacterial leaf blight of rice (BLB) is a devastating disease in rice growing areas of Pakistan. Due to absence of appropriate antibiotic or bactericides in market, disease destroys the whole crop whenever hits to its epidemics in the region. Therefore, present work was conducted to evaluate some newly available bio products in the market to manage the disease efficiently. Five Bio products namely Biosal, Protector, Vega Plus, Rigorous and Vampire were evaluated by in-vivo and in-vitro experiments. In-vitro evaluation was carried out against colony growth of Xanthomonas oryzae pv. oryzae by using inhibition zone technique with different dozes (100 ppm, 200 ppm and 300 ppm) in a CRD experiment with 3 replications. In-vivo evaluation was performed by foliar sprayed bio products on moderately resistant to moderately susceptible varieties (KSK-133 and IRRI-6) in an RCBD Experiment in triplicate. Data were collected at an interval of 7 days. In-vitro experiments revealed that Biosal was most effective while Protector and Vega Plus proved approximately equal in performance for minimizing the pathogen colony. Similarly, In-Vivo evaluation recorded Biosal as most significant while Protector and Rigorous proven comparative for disease reduction under natural field Conditions.
