Soil application of different formulations of carbofuran at 3.0 and 1.5 g.a.i. metre row −1 did not have any impact on vigour and viability of the resultant seeds of sorghum. Fresh seeds from encecap ‘A’, encecap ‘B’ and furadan treated plots contained higher residues than the permissible limits and in artificially aged seeds the quantities were below the permissible limits. The degradation was evident with the growth and development of seedlings grown from fresh and aged seeds. Residues from lower doses dissipated faster than higher doses. The general decline in percentage germination and vigour could not be attributed to the residual toxicity but only to the ageing phenomena.
