| An eco-friendly agent, hydrogen peroxide (H2O2)-based compound, peroxyacetic acid (PAA) gave efficiency against Sporisorium scitamineum teliospore viability. A significant sporocidal effects for all AA + H2O2 combinations tested against S. scitamineum teliospores germination was explored. The highest inhibitory effect (69.9% inhibition) was exhibited at 0.2 AA + 4.0 H2O2 g/L followed by 0.1 AA + 4.0 H2O2 g/L (51.9% inhibition) and 0.2 AA + 2.0 H2O2 g/L (48.9% inhibition). Under field experiments, most of AA + H2O2 treatments were reduced smut disease incidence (SDI) significantly. However, SDI values showed insignificant variances among four treatments, 0.1 AA + 1.0 H2O2 g/L, 0.1 AA + 2.0 H2O2 g/L, 0.1 AA + 4.0 H2O2 g/L and 0.2 AA + 1.0 H2O2 g/L, in two planting dates. While the two treatments, viz. 0.2 AA + 2.0 H2O2 g/L and 0.2 AA + 4.0 H2O2 g/L, showed significant variances values in SDI as they significantly reduced SDI values in May more than in October. Meantime, means of protection values (MPV) of 0.2 AA + 2.0 H2O2 g/L and 0.2 AA + 4.0 H2O2 g/L, showed significant variances in MPV values as they were significantly raised in May being 86.55% MPV more than in October, 70.85% MPV. In May planting date, MPV was significantly higher than in October planting date particularly in the check plants. | ||||
