Residues of phenthoate and chlorfenapyr in peach orchard

Abstract EN

The residual behavior phenthoate and chlorfenapyr peach was studied.

In addition, the effec( of some processing on the degradation of phenthoate and chlorfenapyr was also investigated, '['he results revealed that the rate of disappearance (loss) was faster in case of chlorfenapyr than phenthoate treatments.

The half life values of phenthoate in unwashed peach fruits, leaves and soil were 2.

63, 4.

68 and 1.

8 days, respectively, while in case of chlorfenapyr, these values were 1.

0, 2.68 and 1.

5 days, respectively.

Rinsing treated fruits with tap water removed considerable amounts of phenthoate and chlorfenapyr.

The dislodgeable amounts of the pesticide residues by washing decreased ؟ه the residues on the fruits decreased by time elapsing.

Unwashed and washed fruits could be safely consumed by consumer after 21 and 14 days of phenthoate and chlorfenapyr, respectively, processed )am from peach fruits collected one hour after spraying either with phenthoate or chlorfenapyr could be used safely directly after processing
