In 2007–2009 field experiments in maize were carried out by Institute of Plant Protection – National Research Institute – Sośnicowice Branch. The aim of conducted experiments was to compare the effectiveness of Milagro 040 SC + Callisto 100 SC (nicosulfuron + mesotrione), Mustang 306 SE + Callisto 100 SC, (2,4-D, florasulam + mesotrione), Mustang 306 SE + Milagro 040 SC (2,4-D, florasulam + nicosulfuron) used at recommended and lowered doses with adjuvant at split application with aforementioned tank mixtures applied without adjuvant at full dose application. Herbicides mixed with adjuvant were more effective against Polygonum convolvulus and Echinochloa crus-galli with efficacy ranging from 81% to 100% and from 60% to 97%, respectively.
