Abstract
Methanolic extracts of Ricinus communis and Cassia fistula seeds were tested against root knot nematode Meloidogyne incognita (Kofoid and White) Chitwood. Results depicted absolute larval mortality, reduced and delayed egg hatch. Organic amendment of soil with R. communis and C. fistula seed meals also increased the growth parameters of guar crop. Organic amendment with R. communis @0.5 % concentration and C. fistula @0.3% concentration showed promising results on growth parameters of Guar plants. Moreover, all treatments significantly reduced the number of knots in roots of Guar plants. Phytochemical screening of methanolic extracts of Ricinus communis and Cassia fistula seeds revealed the presence of terpenoids, steroid, tannin, protein, coumarin, saponins, phenol, carbohydrate and flavonoids.
