Residues of triallate in garlic (Allium sativum L.) cloves following preplant incorporation

Abstract

In a 2-yr study, gas chromatography was used to determine the presence of residues of the herbicide triallate in the cloves of cured garlic (Allium sativum L.) bulbs following preplant incorporation of triallate at 2.2 kg ha−1. Triallate residues were not detected in the cloves of mature bulbs in either year. Recoveries of triallate were 82.1 ± 6.9% and 93.8 ± 4.9% from garlic clove tissue fortified at 0.1 and 0.02 mg kg−1, respectively. Key words: Triallate, garlic, residues, gas chromatography
