EFFICACY AND SELECTIVITY OF HERBICIDES TO CONTROL WEEDS IN CHICKPEA CROP AT MOARA DOMNEASCĂ, ROMANIA

Abstract

This paper presents the data regarding the control of weeds in chickpea crop. The observations and determinations aimed the selectivity and efficacy of some simple, complex or associated herbicides, applied pre- and post-emergent, in order to determine their influence on the production yield. The chickpea crop was strongly infested with mono and dicotyledonous species, including perennial species that are difficult to control (Cirsium, Convolvulus, Sonchus). The best results were obtained in the experimental variants in which the pre-emergent treatments were followed by post-emergent treatments. Perennial species were not sufficiently controlled. The herbicide Pulsar 40 (imazamox, 40 g/l) showed phytotoxicity, the harvest being delayed and the production lower.
