Residues of the pesticide selecron on apples and pears grown in Egypt

ABSTRACT

The present study was conducted to follow up residues of selecron on apples and pears after pesticides application on the plant, and to study the effect of washing on the reduction of pesticide residues. The initial deposits of selecron in apples were relatively higher than those in pears and persisted for more than 14 days in both of them, but was not detected after 21 days. The percent removal of the pesticide residues by washing was found to depend on the initial level of pesticide, being greater the higher the pesticide level, since residues remaining on crops after weathering are more difficult to remove by washing than those recently applied
