S. L. Hafez, P. Sundararaj

Abstract


Efficacy of seed crop meals from rapeseed, soybean, cotton and the tare dirt on Heterodera schachti on sugarbeet (I experiment) and Meloidogyne chitwoodi on tomato (II experiment) were investigated in pots. In the first experiment H.schachti larva, viable cysts on the root and total nematode population were significantly reduced by the application of three oil meals. Maximum root weight was observed in the plants treated with rape meaL In the second experiment, among all meals maximum fresh and dry root and shoot weight was observed in the pots treated with rape seed meals. All meals and tare dirt significantly reduced the larval population while viable cyst population and total eggs and larval population were significantly reduced by oil meal alone.
