The present studies cover the phytotoxic effect of two plant extracts viz. Curcuma malabarica, and Hedychium spicatum on Solanum tuberosum with respect to seed (tuber) germination and seedling growth (shoot length) and fungitoxic efficacy of extracts in soil condition. The seeds (tubers) of Solanum tuberosum exposed to selected plant extracts at 5.0 ml dose and the phytotoxicity of extracts was measured in terms of per cent seed germination and the seedling growth in terms of plumule length. The results showed that the germination of seeds (tubers) and the seedling growth of Solanum tuberosum remained unaffected. The study also revealed that the fungitoxic efficacy of extracts in soil condition after re-inoculation of test fungus, remained unchanged.
