Physiological response of lentil cultivars and weeds to metribuzin
Abstract: The purpose of this study was to compare the effectiveness of metribuzin ( 4 amino-b-tert – butyl – 3 – ( methyithio ) – as triazine – 5 ( 4H ) one) on lentil ( Lens esculenta Moench ) cultivars, some associated weeds and its retention on lentil and tumble mustard ( Simbrium altissimum ) leaves . Metribuzin rates were 0,0.12,0.24,0.36,0.48,0.72, and 0.96kg a.i. / ha Results indicated that all rates wnether applied pre or post emergence consisitentiy reduced the dry weight of all cultivars and photosynthesis particularly with increasing herbicide rate. Generally the phytoxicity was more pronounced at post emergence application . Both mayweed (Anthemiscotula ) and mustard ssp. Were effectively controlled by all metribuzin rates . The amount of metribuzin was higher on both outside and inside mustard leaves than lentil.

The selectivity between mustard and lentils contributed partially to the high retention rate of metribuzin on tumble mustard comparing with lentil .
