Evaluating a newer three component herbicide Fulltime, MD for corn (Zea mays) in the central agro-climatic zone of Krasnodar Krai, Russia

Abstract

Among the factors that reduce corn yield, the main one is the infestation of crops. Thus, field experiments were carried out in 2019 and 2020 on the basis of the Federal State Budgetary Scientific Institution "Federal Research Center of Biological Plant Protection" (Krasnodar). The aim of the research was to study the effect of the herbicide Fultime, MD (75 g/L mesotrione + 37.5 g/L nicosulfuron + 17.5 g/L picloram) in corn crops. The experiments were laid out in the form of randomized blocks on plots of 25 m2 in quadruple repetition. In the variants with the use of the herbicide Fultime, MD at the rates of 1.0 and 2.0 L/ha, 82-100% herbicidal effect was noted against dicotyledonous and cereal weeds without a negative effect on corn and a significant preserved grain yield (83.8 and 91.9 %) in comparison with the control (without herbicides).
