In 2007–2010, (at the Sośnicowice Branch of the Institute of Plant Protection – National Research Institute in Poznań, the research was) conducted on the efficacy of herbicide-and-fertilizer mixes applied in maize at the 4–6 leaf stage. Herbicides Maister 310 WG and Mustang 306 SE + Titus 25 WG with adjuvant Actirob 842 EC and Trend 90 EC were used jointly in a mix with multi-compound foliar fertilizers Plonvit Ku and Insol K. The mixes proved to be selective toward the tested maize cultivars and showed a high efficacy 92–99% against the dominant weed species Chenopodium album Linnaeus, Solanum nigrum Linnaeus and Echinochloa crus-galli (Linnaeus) Palisot de Beauvios. Moreover, the tested mix contributed to the increase in cob yield (by 33–38%), grain yield (by 34–36%) and thousand grain weight (by 5–8%). The protein content in maize grain also increased by 4%.
