Abstract:

The residues in vegetable Brassica rapa L. of methylamino abamectin benzoate (MAB) mixed with three plant oils solvent (pine oil, palm oil, pine oil and palm mixed oil ) and xylene solvent were tested in the paper. It was showed that the residue of MAB mixed with three plant oils solvent was higher than that mixed with xylene solvent in Brassica rapa after treatment 1 day and 3 days, and the residue of MAB mixed with palm oil solvent was highest. But after treatment 7 days, the residue of MAB mixed with three plant oils solvent could not be detected, while the residue of MAB mixed with xylene solvent was still detected. The results indicated that the residue of MAB mixed with plant oils solvent in Brassica rapa could be reduced after treatment 7 days, compare with that mixed with xylene solvent.
