In a laboratory trial Dipel (B. t.) at 0.5, 0.75, 1.0 and 2 kg/ha was found more toxic than Delfin, killing 16,36, 76 and 88 per cent larvae of Autographa nigrisigna Walker. Delfin registered 8, 28, 60 and 80 per cent mortality in dosage 0.5,0.75, 1.0 and 2.0 kg/ha, respectively. Dipel 2 kg/ha was on par with endosulfan (0.07%) after 72 h.

Abstract


In a laboratory trial Dipel (B. t.) at 0.5, 0.75, 1.0 and 2 kg/ha was found more toxic than Delfin, killing 16,36, 76 and 88 per cent larvae of Autographa nigrisigna Walker. Delfin registered 8, 28, 60 and 80 per cent mortality in dosage 0.5,0.75, 1.0 and 2.0 kg/ha, respectively. Dipel 2 kg/ha was on par with endosulfan (0.07%) after 72 h.
