EFFICACY OF POST-EMERGENCE HERBICIDE FLAZULFURON FOR WEED MANAGEMENT IN STONE FRUIT ORCHARDS
Published: 12 Sep 2020
Abstract: Due to their longevity and the long distance between rows, orchards are infested every years by annual and perennial monocotyledonous and dicotyledonous weeds species, some of them being very difficult to control. In Romania, in the integrated weed control management, herbicides play an important role together with the other control methods. This paper provides data on weed control in stone fruit orchards with herbicide Flazulfuron. Flazasulfuron is a new sulfonylurea herbicide which inhibits the acetolactase synthase enzyme in susceptible plants, to control a wide range of annual and perennial weeds. Trials were carried out in a drip – irrigated apricot and peach orchard at Agigea, Constanta county, Romania. Experimental plots were placed in randomized complete blocks design, in four repetitions on a vermi – calcic chernozem soil with a clay loam texture, in 2019. Flazasulfuron (250g/l active ingredient) was applied in post emergence at the doses of 0.04, 0.06 and 0.08 kg/ha. Standard reference (Glyphosate 360g/l) was applied at the dose of 4 l/ha. The major weed flora in the experimental fields included: Capsella bursa-pastoris, Lamium purpureum, Fumaria officinalis, Fallopia convolvulus, Matricaria sp., Chenopodium album, Xanthium sp., Malva sylvestris, Veronica sp., Papaver rhoeas, Setaria sp. The results demonstrated that the different rates of Flazasulfuron provide good efficacy on annual dicotyledonous and monocotyledonous weeds in stone fruit orchards, depending on weeds infestation and climatic conditions. The results of herbicide Flazasulfuron were similar to the standard reference.
