The efficiency of adjuvant AGNS 1056-X joint application with herbicide formulations from a group of graminicides Fusilade Forte and Agil, the active substances of which are aryloxyphenoxy propionic acid (AOPPA) derivatives, was investigated in pot and field experiments. In pot experiment winter wheat (Triticum aestivum L.) plants were used as a model of annual grass weeds. To determine the effect of moisture on the phytotoxic effect of graminicides, in pot experiment artificial drought was created by stopping plants watering. In field experiments, the efficiency of certain grass weed species control, in particular yellow foxtail (Setaria glauca (L.) Pal. Beauv.) and barnyardgrass (Echinochloa crus-galli (L.) Pal. Beauv.), was determined. Estimation of fresh or dry weigth of plants aboveground part and in some experiments the total content of chlorophyll in the leaves was used for evaluation of the phytotoxic effects of herbicides or the efficiency of weeds control. Studies have shown that the addition of adjuvant AGNS 1056-X accelerates the development of the phytotoxic effect of graminicides Fusilade Forte and Agil. The development of graminicides phytotoxic effect accelerated more by addition of adjuvant AGNS 1056-X in drought conditions when grass weeds were in a state of water stress. Although in some cases, joint application with adjuvant AGNS 1056-X led to increase of grass weeds control by graminicides, the addition of the adjuvant does not guarantee increased protection efficiency. In this regard, the joint use of graminicides with adjuvant AGNS 1056-X does not allow to reduce the rate of graminicides. To achieve high crop protection efficiency, the graminicides rate should be chosen taking into account the level of weed infestation, stage of weed development and environmental conditions, regardless of whether or not graminicides will be used in conjunction with the adjuvant.
