The results of field trial performed in 2003 & 2004 showed that IWHP(Intermixture With Hexaflumuron and Phoxim)20EC was a kind of effective medicament on controlling five pests, Plutella xylostella(Linné)、Artogeia rapae(L．)、Mamestra brassicae(Linnaeus)、Prodenia litura(Fabricius)and Heliothis armigera Hübner, which are always found on vegetables. Its effective using concentration is between 1：2000 and 1：3000 and its control effect is over 70%~90%. Compared with chlorpyrifos 40EC, a kind of effective medicament traditionally used in the same area, the control effects of IWHP 20EC in the concentration of 1：2000 and 1：2500~3000 are about equal to that of chlorpyrifos 40EC in the concentration of 1：1000 and 1：2000 respectively.
