An attempt was made to modify the general time-concentration-absorption equations for alfalfa proposed by Thomas and Hill on the sulfur dioxide fumigation treatment. The original equations, t (C-0.24) = 0.94, t (C-1, 4) = 2.1 and t (C-2.6) = 3.2 when percentage of leaf destruction was 0, 50 and 100, were modified as t (C-0.24) = 0, t (C-1.4) = 1.1 and t (C-2.6) = 2.3 respectively. Moreover, the original was discussed for generalization and utilization.
