As well as arising the concern about pesticides known as a Carcinogenic or endocrine disorder substrates, magnitude was increased of reducing pesticides in soil or water. In this work, removals of residual pesticides on surface of solid phase were attempted by the photooxidation process with hydrogen peroxide. The optimum conditions for the removals of benomyl (carbamatic pesticide) chlorothalonil (Organochoric pesticide) were 350nm UV wavelegth and 20% (v/v) hydrogen peroxide solution as oxidant. Removals are negligible when UV radiation or the supply of hydrogen peroxide are solely applied on the target compoounds. Removal rates of the pesticides are accelerated by UV radiation with hydrogen addition. After 20 min of the treatment, about $2{\mu}g/cm^2$ of benomyl and $1,88{\mu}g/cm^2$ of chlorothalonil were disappeared on the surface of the solid phase.
