TETRACONAZOLE AND INDOXACARB PESTICIDES RESIDUES IN AND ON TOMATO FRUITS AND EFFECT OF SOME ENVIRONMENTAL FACTORS.
Pesticides Analysis Res. Div.I Central Agric. Pesticides Lab.I Agric. Res. Center, Dokki.Giza.Egypt.
Abstract
The residual behaviour of tetraconazole and indoxacarb pesticides on and in
tomato fruits was studied under the environmental condition of Egypt.
Residue analysis showed that the initial deposits of tetraconazole and
indoxacarb in unwashed tomato fruits were 12.664 and 9.52 ppm. respectively .These
figures decreased to 0.98 and0.02 ppm after 28 and 21 days after treatment of
tetraconazole and indoxacarb, respectively. Also results showed that the washing
process by tap water of initial time dissipated 54.14 and 45.86 % oftetraconazole and
indoxacarb,respectively from tomato fruits.
0n the other hand. the effect of temperatures, UV-rays and direct sunlight on
tetraconazole and indoxacarb degradation were studied.
The data showed that sunlight more effective than UV-rays in degradation of
tetraconazole and indoxacarb. Tetraconazole and indoxacarb were reduced after 24
hours of exposure to direct sunlight by 89.74 and 88.7%. respectively. While 24 hours
exposure to UV-rays reduced 45.38 and 57.7% for tetraconazole and indoxacarb,
respectively.
Also results obtained that tetraconazole and indoxacarb showed a high
degradation rate when exposure to high degrees of temperature 45-50°C within the
period of experiment.
