Effect of soil amendment with urea coated with 'Nimin' and natural oils on the root-knot nematode (Meloidogyne Incognita) and the growth of okra

摘要

Much work has been carried out on the use of organic amendment with oil cakes for control of plant parasitic nematodes (4). They are often used in bulk amounts and are not subject to limitations in usage as are nematicides. The present study was carried out to examine the effect of soil amendment with urea coated with 'Nimin' and oils of neem, castor and rocket-salad on the root-knot nematode and growth of okra.
