Abstract

Field experiments were conducted during rabi 2017 and 2018 at the Vegetable Research Farm, College of Agriculture, Central Agricultural University, Imphal to evaluate the efficacy of cow-urine + indigenous plant extracts against cabbage aphid Brevicoryne brassicae. The results revealed that three sprays of Neemazal T/S (azadirachtin 1500 ppm) @ 1500 ml/ha was the most effective with minimum aphid counts of 28.92 aphids/plant (2017) and 28.94/plant (2018), respectively. The yield (21.88 t/ha and 22.50 t/ha) was also maximum with this treatment.
