Evaluation of Herbicide Mixtures for Weed Control in Maize (Zea mays L.)

摘要

A field experiment was carried out to evaluate the tank-mix efficacy of new hydroxy-phenyl pyruvate dioxygenase (4-HPPD) herbicide with atrazine for weed control in maize {Zea mays L.) during kharif 2014. The experimental field was infested with fivegrasses, six broad leaved weeds and a sedge. Tank-mix application of topramezone or tembotrione @ 25.2 or 105 g/ha with atrazine @ 250 g/ha along with adjuvants effectively controlled all annual grassey weeds except Cynodon dactylon which was bleached but soon recovered after sometime Cyperus rotundus was also not very effected, where as it resulted in excellent control of broad leaf weeds. These treatments also recorded highest grain yield and yield attributes on par with hand weeding at 20 and 40 DAS.
