Abstract: Cutting of herbicide dosage without compromising grain yield can cause to less environmental pollution and lower production costs.Field experiments were laid out over years 2012 -2014 to appraise the efficacy of reduced rates of a new generation post-emergence herbicide verdict in combination with biocontrol agent to suppress three major weeds (Chenopodium album, Avena fatua and Capsella bursa-pastoris) in wheat (Triticum aestivum L.) under the condition of Non-chernozem zone, Moscow region.Below labeled rate 0.3 kg/ha -1 plus bio-agents was quite effective in suppressing total weed populations.This study revealed that a favorable level of weed reduction in wheat fields was obtained when lower herbicide rate 0.3 kg/ha -1 and bio-agents were used, that was comparable to the result which achieved for registered verdict dose as 0.5 kg/ha -1 .Hence, despite the higher weed reduction efficacy was obtained with herbicide in registered label dose plus biocontrol agent, but the differences were not significant compared to below herbicide dose 0.3 kg/ha -1 .Meanwhile, the best energy output (90.3 GDj/ha -1 ), agricultural efficiency (19.9%) and wheat grain yield 7.80 t/ha -1 were achieved when reduced herbicide rate 0.3 kg/ha -1 combined to biological agent were applied.
