In recent years, the greatest problems in maize crops represented Johnson grass which caused great damage during maize cultivation. Negative effects of Johnson grass are extremely obvious in maize cultivation in repeated sowing or monoculture. If appropriate herbicides are not used, Johnson grass will reduce plant height, yield, and 1000 grain weight, expecially in a repeated sowing and shorter monoculture. For the control of Johnson grass in maize growing herbicides from the group of sulfonylurea preparations are used. If due attention is payed to the application time, quantities and interaction of insecticides and sulfonylurea herbicides, they can be applied in mercantile maize crops without greater risk.
