Weeds response to the biocontrol agents in integration with reduced rates of herbicide

Abstract

Field experiment was conducted to study the biological agents efficacy in combination with reduced doses of new generation herbicide (Verdict) in four rates (0, 0,2, 0,3 and 0,5 kg/ha) to control weeds in winter wheat ( Triticum aestivum L. ), trial was laid out in a randomized complete block design with four replications at Moscow research institute of agriculture, Nemchinovka, Russia. Result indicated that recommended dose as 0,5 kg/ha in combination with biological agents was quite effective in reducing density and dry weight of Viola arvensis and Poaceae . Thus, intermediate Verdict rate as 0,3 kg/ha + biological agents also had appropriate effect in reducing dry weight and density both of V. arvensis and Poaceae . Stelaria media was affected and diminished by each three of treatments desirably compared to control.
