Abstract

Survival of Pseudomonas solanacearum in peanut seeds.

Abstract

Survival of P. solanacearum in groundnut seeds was investigated in newly harvested seeds and in seeds stored for 1 year. Wilt incidence was recorded after sowing seeds artificially inoculated with P. solanacearum and the bacterium was isolated from 4% of seeds from wilted groundnut plants. P. solanacearum was isolated from infected seeds with varying water content. Temp. of the environment, groundnut variety and seed water content were shown to affect pathogen survival in the seeds. No P. solanacearum was isolated from seeds stored for 1 year.
