Abstract

The effect of four herbicides (paraquat, pretilachlor, glyphosate, and 2,4-D Na salt), and a herbicidal mixture (anilofos + 2,4-D EC) on growth and sporulation of Fusarium pallidoroseum was evaluated under in vitro conditions. Pretilachlor (1.0, 0.25, 0.06, and 0.02 kg ai ha–1), 2,4-D (1.0 and 0.25 kg ai ha–1), and 2,4-D + anilofos (0.4 and 0.1 kg ai ha–1) completely inhibited fungal growth and sporulation, while paraquat and glyphosate (0.01 kg ai ha–1) showed a lesser extent of growth inhibition (68 and 62 % of control respectively). Lower concentrations of paraquat (0.05 and 0.01 kg ai ha–1), glyphosate (0.8, 0.2, 0.06, and 0.02 kg ai ha–1), 2,4-D (0.06 and 0.02 kg ai ha–1), and anilofos + 2,4-D (06 and 0.02 kg ai ha–1), however, supported F. pallidoroseum growth.
