Abstract:

An experiment to evaluate the bioefficacy of pinoxaden in combination with broad-leaved herbicides 2,4-D, metsulfuron and carfentrazone  in wheat was conducted at  Hisar during 2006-07 and 2007-08. Dominant weed flora of the experimental fields were Phalaris minor among grassy weeds and Chenopodium album, Melilotus indicia and Rumex dentatus among broad-leaved weeds. The tank mix application of pinoxaden with broad-leaved herbicides proved significantly effective in reducing density and dry weight of weeds and gave 85-100 % control of broad-leaved and 100% control of P. minor. Tank mixing of carfentrazone with pinoxaden although caused injury in terms of yellowing of tips but injury symptoms disappeared within 15 days after spray and did not result in any detrimental effect on grain yield of wheat. Application of broad-leaved herbicides 7 days earlier than pinoxaden or 7 days after application of pinoxaden also proved effective in controlling P. minor and broad-leaved weeds. Tank mixture of 2,4-D with pinoxaden did not result any antagonistic effect as anticipated as is evident by number of spikes, plant height, and number of grains per panicle and grain yield with use of 2,4-D were at par with weed free check.
