The invention relates to a chlorpyrifos*phoxim emulsifiable concentrate, which is composed of a technical product of chlorpyrifos, a technical product of phoxim, emulsifier (0204C), and solvent of xylene which are compounded together. Field drug efficacy experiments prove that the agricultural chemical has strong permeation in the use for preventing and controlling the grass leaf rollers, the knockdown speed is quick, the duration is long, the poisoning phenomenon does not exist, and thereby the agricultural chemical is favorable for reducing the production cost of rice and increasing the income of peasants.
