The study of the relationship between wheat and weed species is important in finding out the measures by which the competition can be reduced. Fighting only with herbicides gradually lost its importance due to the new requirements for agriculture, due to the accumulation of noxes in the soil. The luvosol contains large amounts of weed seeds reserves, and their biomass from wheat was on average 6.7 t/ha. Weed development can be stopped, not by eradication, but at levels where crop losses no longer occur. Herbicides used in wheat crop gave good results after April-May. The dose reduction in the wheat crop will be done gradually, with care, namely 25% for 2,4-D acid and 25-50% for chlorsulfuron. Late application of hormones is very critical because it is possible to destroy grain production (Ionescu, 2000). Further research is needed for other herbicides. In wheat, herbicides reduced the degree of coverage (GA) from 60% to 24%, and wheat production increased by approx. 1-2 t/ha. SU type products have a very good control over weeds, due to their broad spectrum.References
