Magnitude and impact of different botanical and synthetic chemical treatments on the yield attributes of Mustard infested by Aphid (Lipaphis erysimi Kalt.)

The present study was conducted to evaluate the impact of different natural and synthetic chemicals on the yield attribute of mustard crop. The different yield attributes viz., average height of the plants, number of branches, number of pods per plant and boldness of seeds [average weight (mg) of 100 seeds and number of seeds per gram] and yield (q ha⁻¹) shows the most effective treatment was Endosulfan followed by Fenvalerate, Dimethoate, Neemazal, Neemgold, Achook WSP, Neemta-2100, Nimbecidine, RD-9 Repelin and Annona EC formulation at their recommended dosages. The performance of all the treatments proved statistically superior over untreated control at 5% level of significance. The botanical treatments were observed to have the same impact as synthetic treatments on different yield attributes of mustard crop. The effect of dimethoate and fenvalerate were observed to be statistically at par with each other. Synthetic chemicals were superior to the natural botanical formulations, although the natural chemicals were superior to the untreated control and have similar impact on different yield attributes of mustard crop
