Abstract
BACKGROUND: This research has investigated the residue patterns of insecticide flubendiamide on three species of peaches with different surface forms, and the residue amounts of them when mixed with a spreader. METHODS AND RESULTS: Pesticide used for field application on peaches was 20% flubendiamide of suspension concentrate(SC) and was sprayed at a recommended rate. The residue amounts of flubendiamide in peach were analyzed by HPLC equipped with UV detector. After the observation with a microscope, the rank of fuzz amount on peach's surface was Kurakatawase, Wolmi in descending order and Cheonhong did not have any fuzz. The residue amounts of flubendiamide were 0.54 mg/kg for Kurakatawase, 0.43 mg/kg for Wolmi and 0.10 mg/kg for Cheonhong, respectively. When flubendiamide was used with a spreader, polyoxy ethylene methylpoly siloxane, the residue amount for Kurakatawase barely changed at 0.55 mg/kg regardless of mixing with a spreader, and at 0.53 mg/kg for Wolmi. In Cheonhong, the residue amount was 0.48 mg/kg, which increased by 4.8 times due to the use of a spreader. CONCLUSION: This result indicates that the residue amounts of flubendiamde were affected by the surface forms of peaches, and in the presence of a spreader the residue amount did not increase in fuzzy species, but was affected greatly for species without fuzz.
