Objective: To evaluate the biological effectiveness of progressive doses of the herbicide Condraz® (tritosulfuron + dicamba) in post-emergence in dicotyledonous plants grown in consortium with corn in a greenhouse. Design/methodology/approach: The research was performed out in a greenhouse within the facilities of the Colegio Superior Agropecuario del Estado de Guerrero. Dekalb 357® corn was established, planted in a consortium with sunflower, to measure the response to different dosages of the herbicide Condraz® (tritosulfuron + dicamba). We worked with a completely randomized block experimental design (DBCA). Results: The treatments were 100% effective, because they eliminated the sunflower plants used as a representative of dicotyledonous weeds; while, in treatment T1 (water) the number of these was not affected, which was 10 sunflower plants per pot in the two experiments. Limitations on study/implications: Our results are specific for the management of dicotyledonous weeds in corn. Findings/conclusions: Condraz® herbicide is effective in eliminating dicotyledonous weeds when applied in doses ranging from 100 to 190 g per ha.
