In the years 2007–2009 field experiments with maize were carried out under reduced tillage. Brown soils were boron deficient and medium affluent in available zinc. The mixture of mezotrione and rimsulfuron was applied in experiments with split dose method (½ dose at 3 leaf stage and ½ dose at 8 leaf stage) in conjunction with micronutrient fertilizers in the form of chelate boron and zinc compounds (Insol B and Insol Zn). The possibility of joint application of mezotrione and rimsulfuron mixture with Insol B and Insol Zn was stated. The high efficiency of the mixture in reducing the mono and dicotyledonous weed species was also proved. This allowed obtaining high maize grain yields, containing more boron and zinc as well as more high quality protein and starch in comparison with both variants – untreated with herbicides and untreated with the micronutrients.
