The efficacy of certain broad-leaved herbicides and graminicides in soybean fields as affected by herbex

Abstract: Field experiments were conducted at Mallawi Research Station for two successive seasons 1990 and 1991 to study the effect of herbex as adjuvant on the efficacy of certain broad - leaved herbicides , I . e . bentazon and fomesafen and graminicides , I . e . fluazifop and Haloxyfop on soybean yield and associated weeds . combined analysis of the seasons of the two seasons indicated that 1.0 L / fed . of herbex could replace half the rate of bentazon or two thirds of the rate of fomesafen without loosing any significant activity on the control of total broad - leaved weeds or the yield . The response of graminicides to herbex was much lower that observed for the broad - leaved herbicides . Thus, one litre of herbex could replace 1.0 L/ of fluazifop (only quarter of the recommended rate) and half a litre of Haloxifop (one third of the recommended rate) without loosing any significant activity on the control of total grasses or yield . Haloxyfop at 0.5 L / fed . + 1 L of Herbex resulted in the same yield of 1.5 L of the same herbicides or 4 L of fluazifop alone
