| Severity of 3-diseases including bacterial leaf streak, downy mildew and Curvularia leaf spot were reduced ranging 40.4-83.0 percent evaluated at 45-day old plants that cell suspension of P38 and PCL21 showed significantly higher in disease suspension than KPS46 and copper hydroxide chemical, except SP007s (P=0.05). Regarding microbial formulation response, SP007s in talc-based formulation was the best results toward control diseases concerned and increased yield quality (2.7 percent lowest unsatisfied kernel and 17 brix sweetness) and quality (1,803.2 kg/rai). It was shown that application of indigenous antagonist with its host specificity, and formulated cells is greater effective delivery system in disease management strategies than introduced... |
