Investigations on the Insecticidal Control of the Phyllody Disease of Sesamum

Madras Agricultural Journal, 1977
Field trials with insecticides were conducted for the control of the phyllody disease of sesamum. No significant control of the disease was obtained with granular insecticides applied in soil. Five spray applications of sevithion (carbaryl 40 per cent+ methyl parathion 10 per cent) at 1 kg of the product per ha or monocrotophos 0.025% were found to be ...
