Author(s): Shahin Khan, SPS Tomar and Pawan Kumar Raghuwanshi
Abstract: Field experiment was conducted to find out the appropriate time of monocrotophos application and number of spraing against mustard aphid, Lipaphis erysimi (Kalt.). Three and more sprays including spray at initiation of aphid infestation monocrotophos gave maximum protection against aphid and registered higher grain yield also. Three sprays at 15 days interval starting from initiation of aphid infestation gave maximum net return (Rs. 23220/ha.) but one spray at 15 days after initiation of aphid infestation were the most economical (1:14.8).
