| Abstract: | Comparative study of the pathogenicity of 3 isolates of R.solani belonged to 3 different pathogenic-type from Guizhou to rice adult-plant was conducted by artifical inoculation in pot-culture and the field in 1990-1992. The pathogenicity of No 147 isolate belonged to ThA is the best.It showed fast germination of the sclerotia,flourishing growth of the mycelia,and short latent period showed the lesion on rice plant.This paper discussed also the relationship between rece varities, isolates,planting density and manuring to disease development,and the dynamic of disease development in the field. |
