摘要

Bio- efficacy of neem products, insecticides and admixtures of neem and methyl demeton was studied against the incidence of coriander aphid, Hyadaphis coriandari Das. The results indicated that the incidence of coriander aphid was reduced to the lowest extent with a maximum yield and net profit in the crop treated with neem oil 1% (983 kg/ha and Rs. 12165 per ha), neem kernel extract (in cow urine) - 3%+methyl demeton - 0.03% (967 kg/ha and Rs. 11295 per ha), cartap hydrochloride 0.1% (967 kg/ha and Rs. 9660 per ha) and phenthoate 0.1% (917 kg/ha and Rs. 9000 per ha).
