• a conventional granule type product comprising an insecticide and fungicide mixture for seedling box application was selected as a comparative example 2.
• Pesticide untreated germinated seed is sown onto nursery with same nursing method as comparative example 1.
• Transplanting was conducted after treating-scattering the pesticide onto nursery box at 0 to 7 days before transplanting.
• Plot for efficacy trial is designed as 30m 2 (5m * 6m, In general, 1 seed mat can be transplanted) and the depth of paddy water is controlled at 3-5cm.
• the evaluation of fungicidal efficacy is calculated by comparing disease severity of untreated plots with those of treated plots.
