“…The significantly reduction of total number of weeds were due that, glyphosate is more effective on broad leaved weeds particularly rhizomatous and deep-rooted perennial weeds, and oxyfluorfen which is known for its efficacy against all types of weeds. The studies are in confirmation with the earlier works by Patil et al (2008) [11] , Bajwa (1990) [3] and Bajwa et al (1992) [4] . Glyphosate's effectiveness after application may be attributed to its rapid action as a systemic herbicide that kills both the root and shooting system and causes the weeds to die within a week.…”

“…The results are in line with those of Patil et al (2008) [11] and Ramteke et al (2012) [13] who reported that high yield per hectare of grape is because of more weight and number of bunched per vine. Prathiba et al (1995) [12] also reported that, herbicide treatments recorded more yield in grape because of more number of bunches per vine.…”

“…According to Patil et al (2008) [11] who reported that, uncontrolled weed during two year of investigation caused 47.72 % reduction in Thompson Seedless grape yield and Ramteke et al (2012) [13] and (2013) [14] also stated that, unmanaged weed during the crop production period resulted in reduction of 36.05 % and 45.66 % yield, respectively. Susaj et al, (2013) [15] also reported that unmanaged weeds caused 34.14 % yield in wine grapes.…”

A field experiment on "Impact of different herbicides on weed control in grape (Vitis vinifera L.) cv. 2A Clone" was carried out during October 2019 to March 2020 at fruit orchard, Main Horticultural Research and Extension Center (MHREC) Sector no 70, University of Horticultural Sciences, Udyanagiri, Bagalkote, to test the effect of various herbicides for controlling weeds in the vineyards under dry zone climate of north Karnataka. The trial was laid out in randomized complete block design (RCBD), having ten treatments with three replications. Lower number of total weeds/m 2 4.67, 9.00, 16.00 and 23.00/m 2 at 30, 60, 90 and 120 days after spraying was recorded with T6-tank mix post-emergent application of oxyfluorfen 23.5% @ 1.0 lit/ha + glyphosate 41% SL @ 2.62 lit/ha. Among different herbicides, the higher yield per hectare (32.31 t/ha) and the lower weed index (5.76 %) were recorded with tank mix post-emergent application of oxyfluorfen 23.5% @ 1.0 lit/ha + glyphosate 41% SL @ 2.62 lit/ha. No phyto-toxicity symptoms viz. leaf tip/surface injury, wilting, vein clearing, necrosis, epinasty and/ or hyponasty were observed.

“…Pendimethalin, a dinitroaniline, and oxyfluorfen a diphenyl ether, are selective pre-and postemergence herbicides that are used to control many annual broadleaf weeds and grasses in many crops including, vineyards (Kaps and Odnea 1991;Mitchem and Monks, 2005;Patil et al, 2008;Alister et al, 2009). Flazasulfuron is a new, recently registered selective, systemic sulfonylurea in viticulture in R. N. Macedonia.…”

Two-year field trials were conducted at two winegrowing districts (Kavadarci and Skopje in 2016 and 2017) to evaluate wheather oxyfluorfen, pendimethalin and flazasulfuron can replace early post-emergence (EPOST) application of glyphosate in established vineyard until its application in early summer period. The weed vegetation in vineyards in both years was consisted mainly of Chenopodium album L., Setaria viridis (L). Beauv., Papaver rhoeas L., Xanthium strumarium L., Lolium multiflorum Lam., Sorghum halepense (L.) Pers. and Cynodon dactylon (L.) Pers. Pendimethalin, oxyfluorfen and flazasulfuron efficiently reduced predominant annual weeds and S. halepense seedlings in 2017, but not in 2016. PRE herbicides, regardless year, had no significant effect on C. dactylon. Opposite, the efficacy of EPOST applied glyphosate was significantly lower in 2017 compared to 2016. LPOST glyphosate applied at 2.0 l ha-1 provided at least 94 % control of dominant annual broadleaf and grass weeds. LPOST application of glyphosate at 2.0 l ha-1 and glyphosate at 2.0 and 4.0 l ha-1 resulted in unsatisfactory weed control of predominant perennial S. halepense, and C. dactylon, respectively. LPOST glyphosate applied at 4.0 l ha-1 provided control of S. halepense by 84 % or more. LPOST glyphosate applied at 8.0 l ha-1 reduced the amount of S. halepense and C. dactylon at least 97 %. Grapevine yield of both varieties was not lower in all herbicide treatments in 2016 compared with 2017. However, yield in the PRE herbicide treatments fb 2.0 and 4.0 l ha-1 glyphosate was collectively 15-19 % and 17-19 % lower compare to PRE herbicide treatments fb 8.0 l ha-1 glyphosate and standard two applications of glyphosate, respectively for both years and districts. No impacts to grapevine growth were observed from PRE herbicide treatments at either district
