The results were highly significant and revealed that of the three test plants; neem gave the maximum larval mortality followed by Ak and datura. The standard extracts were more toxic to Tylenchulus semipenetrans larvae than other concentrations. Similarly, maximum mortality was recorded after 48 h of exposure followed by 24 and 12 h. When the standard extracts of leaves of the test plants were applied in pots on Citrus jambhiri, growth variables were enhanced to the maximum by neem followed by Ak and datura. On the other hand significant reductions were recorded in nematode populations and rate of multiplication in treatments where extracts were applied as compared to control.]]>Anonymous, 2003pp: 89pp: 89Milne, D.L.,19773835838Baines, R.C., O.F.
