Abstract
A field experiment was conducted at Research Farm of MPUAT, Udaipur for two consecutive years during 2008–09 and 2009–10 to evaluate the efficacy of different doses of quizalofop-ethyl as postemergences (at 4–6 leaf stage of weeds) in blackgram and residual effect thereof on succeeding Rabi crops (wheat, gram and mustard). The experiment comprising five weed control treatments, viz. quizalofopethyl at 37.5 and 50 g/ha as post-emergence, pendimethalin 750 g/ha as pre-emergence, farmers practice of two hand weedings at 20 and 35 days after sowing (DAS) and weedy check, was conducted in randomized block design with four replications. To study phytotoxicity, quizalofop-ethyl 100 g/ha was also included in addition to above treatments. In the experimental field, more than 50% weeds were dominated by Echinochloa spp. Results revealed that among the herbicidal treatments, quizalofop-ethyl 50 g/ha recorded the lowest narrow-leaved weed density and dry weight at 30 DAS and at harvest during both the years. Quizalofop-ethyl irrespective of its doses was not effective against broad-leaved weeds. The weed control efficiency of quizalofop-ethyl 50 g/ha was 81.3% than the highest (85.6%) under two hand weedings against grassy weeds at harvest. Number of branches and pods/plant, seeds/pod and grain and stover yields of blackgram were also superior in plots treated with quizalofop-ethyl 50 g/ha or two HW. Quizalofop-ethyl was found safe to blackgram, and did not cause any residual toxicity to succeeding crops.
