Chickpea (Cicer arietinum L.) is known to be sensitive to many chemicals and therefore the use of herbicides for the control of dicotyledonous weeds is limited. The research was conducted in 2019-2020 at A.R.D.S. Teleorman, with different applied herbicide associations being studied. The research focused on the selectivity and effectiveness degrees for the control of monocotyledonous and dicotyledonous, annual and perennial weeds, by applying combined herbicides treatments. From the analysis of the 12 variants, the experimental variant with the association of herbicides Gardoprim Plus Gold 500 SC (4.0 l) + Merlin Flex (0.3 l). Applied during pre-emergence phase, this solution registered a higher efficiency, of 96-99%, for both monocotyledonous (Avena fatua; Echinochloa crus-galli; Setaria spp.) and dicotyledons (Amaranthus retroflexus; Chenopodium album; Chenopodium polyspermum; Hibiscus trionum; Polygonum convolvulus; Sinapis arvensis) weeds. In the embodiments Gardoprim + Merlin 500 SC Plus Gold Flex Flex Leopard 50 EC + Merlin, there is a chemical weed control that significantly exceeded, provided statistically the untreated control and with production increases between 115-246 kg/ha.
