Abstract

Two formulations of the systemic fungicide metalaxyl were used as seed treatment for the control of pearl millet downy mildew in seven field experiments with downy mildew susceptible pearl millet hybrid NHB-3. The treated seeds were stored at 5, 12, 25–30, 40 and 45°C and sown after 7, 60, 120, 180, 240, 300 and 360 days storage. Significant reduction in downy mildew was obtained with all fungicide treatments under severe downy mildew pressure. Storage temperatures for 7, 60, 120, 180, 240, 300 and 360 days did not affect seed germination. The plots sown w.ith metalaxyl 35 SD (2 g a.i./kg) treated seeds stored at 12, 28–30 and 40°C for a period of 7 days developed significantly less downy mildew than check plots. There were no significant differences among the plots sown with treated seed. The grain yields from the treated plots were also significant. Downy mildew incidence in the plots sown with metalaxyl 25 WP (2 g a.i.jkg) treated seeds stored at 5, 12, 25–30 and 45OC for 60, 120, 180, 240, 300 and 360 days was significantly less than the untreated plots with consequent increase in grain yield. However, plots sown with treated seeds stored at 45°C had more downy mildew than plots sown with treated seeds stored at other temperatures.
