Abstract
Although the removal efficiency of residual pesticides using tap water were ranged from -1.25 to $13.27\%$, the removal efficiencies of residual pesticides using both powder CaO and liquid CaO were $5.16\~l7.61,\;8.7\~41.59\%$, respectively. And those results showed much higher residual effect of the CaO washing than tap water washing. Natural CaO made by burning of scallop-shell considered to be a good reducing agent for pesticides. Furthermore, liquid CaO showed much higher removal efficiency than powder CaO. However, powder CaO also can be used as a good natural eliminator of pesticides in Mini-Tomato.
