Weed control in root crops grown on organic soils

Weed control in root crops grown on organic soils. Dusky, J. A. (Everglades Res. Educ. Cent., Univ. Florida, Belle Glade, FL 33430, USA). Proc. Fla. State Hortic. Soc., Volume Date 1984, 97, 168-71 (English) 1985. CODEN: PFSHA7. ISSN: 0097-1219. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) During 3-yr, herbicides were evaluated for weed control efficacy and carrot (Daucus carota) and radish (Raphanus sativus) crop tolerance on org. soils. In radish, preemergence applications of CDEC [95-06-7] (2.0 lb/acre), propachlor [1918-16-7] (4.0 lb/acre), metolachlor [51218-45-2] (1.5-3.0 lb/acre), thiobencarb [28249-77-6] (4.0 lb/acre), alachlor [15972-60-8] (2.0 lb/acre), pendimethalin [40487-42-1] (1.0-2.0 lb/acre) and diethatyl-ethyl [38727-55-8] (4.0 lb/acre) provided adequate control of goosegrass (Eleusine indica), spiny amaranth (Amaranthus spinosus), lambsquarter (Chenopodium album), and purslane (Portulaca oleracea). Almost all herbicide treatments resulted in reduced yields. In carrots, preemergence applications of metolachlor (3.0 lb/acre), alachlor (3.0-6.0 lb/acre), thiobencarb (4.0-8.0 lb/acre), metribuzin (0.25-0.5 lb/acre), propachlor [1918-16-7] (2.0 lb/acre), linuron [330-55-2] (1.0-2.0 lb/acre), and diethatyl-ethyl (4.0-6.0 lb/acre) provided acceptable control of spiny amaranth and purslane for 4 wk. However, propachlor and metribuzin reduced crop vigor. Preemergence applications of metolachlor, propachlor, and diethatyl-ethyl provided acceptable control of goosegrass and broadleaf panicum (Panicum adspersum) 4 wk after treatment. Postemergence applications of fluazifop-butyl [69806-50-4] (0.125-0.25 lb/acre), sethoxydim [74051-80-2] (0.15-0.3 lb/acre), haloxyfop-methyl [69806-40-2] (0.15-0.3 b/acre) and DPX-Y6202 [76578-14-8] (0.25 lb/acre) provided excellent control of grasses. Combination postemergence applications of linuron (1.0 lb/acre) or thiobencarb (4.0-6.0 lb/acre) plus fluazifop-butyl (0.25 lb/acre) provided excellent control of all weed species for the entire growing season.

Grass control with postemergence grass herbicides and contact herbicides

Grass control with postemergence grass herbicides and contact herbicides. Bell, C. E.; Kemp, C. (Coop. Ext., Univ. California, El Centro, CA, USA). Proc. West. Soc. Weed Sci., 38, 179-84 (English) 1985. CODEN: WSWPAF. ISSN: 0091-4487. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) The postemergence grass herbicides sethoxydim [74051-80-2], fluazifop-Bu [69806-50-4], pp005 (Bu (R)-2[4-[5-trifluoromethyl-2-pyridyl]oxy)phenoxy]propionate) [79241-46-6], and DPX-Y6202 [2-[4-[6-chloro-2-quinoxalinyl)oxy]phenoxy]propionic acid Et ether)] [76578-14-8] were evaluated against Mexican spragletop (Leptochloa uninervia), jungle rice (Echinochloa colunum), prairie cupgrass (Eriochloa contracta), and Italian ryegrass (Lolium multiflorum) in combination with diquat [2764-72-9]. The combination of fluazifop-Bu with diquat, applied a few days after, was numerically but not significantly better than fluazifop-Bu applied alone at the 2 highest rates (0.2 and 0.3 lbs/acre) for control of ryegrass. The combination of any grass herbicide with diquat killed mature jungle rice after 15 days, whereas no grass herbicide applied alone killed jungle rice. There was a significant difference between control of prairie cupgrass with the combination compared to the grass herbicides applied alone. However, the combination did not perform better than the grass herbicides alone for control of Mexican spragletop.
