Abstract
Quizalofop ethyl, a phenoxy propionate herbicide is used for post emergence control of annual and perennial grass weeds in broad-leaved crops in India. The experiments were designed to study the harvest time residues of quizalofop ethyl in black gram for two seasons. At harvest time, the residues of quizalofop ethyl on black gram seed, foliage and soil were found to be below the determination limit of 0.01 mg kg−1 following a single application of the herbicide at 50 and 100 g a.i. ha−1 for both the periods. Application of the herbicide is quite safe from a consumer and environmental point of view.
