Seed treatment with metalaxyl (apron 35SD) controlled the downy mildew upto 30 days after sowing. Seed dressing (metalaxyl 5g a.i./kg seed) followed by a 0.2 per cent a.i. spray of ridomil ZM-280FW at 23 days after sowing gave the best results with disease incidence 77.2 per cent less at 40 D.A.S. and yield 100 per cent more than the check. At dough stage, per cent infection index was a better measure than per cent disease incidence to assess treatment differences. Harvest time residues of metalaxyl and of ziram were practically nil.
