Within the period 2011-2012 in the experimental field of the Agricultural University, Plovdiv, we conducted field experiments using the herbicides Lumux 538 SK, Gardoprim plus gold 500 SK, Wing, Merlin flex, which were applied to the soil after planting the crops and before their germination and also the herbicides Laudis OD, Elumis, Stelar, Kaspar 55 WE, which were applied to the leaves during the vegetation period of the maize. The experiments were made using the block method over an area of 21 m2 in four repetitions. It has been established that the herbicides demonstrate excellent selectivity for this crop, which was measured on the EWRS scale in marks and control the existing annual late-spring types: Amaranthus retroflexus L., Chenopodium album L., Solanum nigrum L., Setaria spp., Echinochloa crus-galli L. and others. The weeds in the control sample without herbicides have a very high density and on the 40th day after treatment their number reaches 602 plants/m2.
