5 HISTORY OF CARPET The knotted pile carpet probably originated in the 3rd or 2nd millennium BC in West Asia, perhaps the Caspian Sea area (Northern Iran) or the Armenian Highland, although there is evidence of goats and sheep being sheared for wool and hair which was spun and woven as far back at the 7th … Lugo, M. de L., Ortiz, C.E., and Rosa-Marquez, E. 2001. Cyanazine was phytotoxic to sweet corn; other preemergence herbicides gave good control and crop yields. In another yam experiment, imazethapyr (0.112 and 0.224 kg ai/ha) gave controlled weeds much better than lactofen (1.68 and 3.36 kg ai/ha) when both Ruiz. The term sisal may refer either to the plant's common name or the fibre, … However, the final tuber yield did not reflect the improved weed control by imazethapyr. Coriander was highly tolerant to all five herbicides tested.Impacts(N/A)Publications, Progress 01/01/92 to 12/30/92OutputsEight field tests were conducted to evaluate ten herbicides, and a plastic mulching treat- ment for weed control in eight crops. The best grass control at three weeks in C. moschata at Lajas area was provided by plastic mulch, glyphosate preplant alone or combined with clomazone.ImpactsUse of paraquat will replace at least two handweedings in arracacha, thus reducing production cost. Mosses, plants in the Bryophyta division, have been around for more than 400 million years making them old enough to have predated dinosaurs and tough enough to have survived being walked around on by all kinds of large, prehistoric creatures. In pumpkin, handweeding postemergence application of metolachor at 3.36 kg ai/ha gave best weed control in one trial, the highest yield was obtained from metolachor at 3.36 kg ai/ha rotavator handweeding treatment in another trial. The taxon Cenchrus purpureus (Schumach.) 1999. Carpet grass, (Axonopus fissifolius), mat-forming perennial grass of the family Poaceae, native to sandy soils in southeastern North America. The cleaning industry is also one of the most recession-proof industries out there! Nutsedges (Cyperus spp.) Ametryne & Prometryne were the least injurious. LAWN WITH SHADE GRASS . Pendimethalin at 4.48 kg ai/ha also gave a high yield whereas hexazinone at 4.48 kg ai/ha and imazethapyr at 1.17 l/ha resulted in the lowest yields. Propanil-Oxidiazon was the best combination. Round-up gave better weed control than Paraquat in plantain at Corozal, at corresponding rates. Beans: Strategy 1 = STG 1 (trifluralin at 0.75 kg/ha, pre plant incorporated (PPI), followed by bentazon at 0.75 kg/ha, POST and sethoxydim (0.37 kg/ha, POST) and STG 4 (imazethapyr at 0.06 kg/ha, PRE, followed by bentazon and sethoxydim, POST) significantly reduced weed density at Juana Diaz and Isabela in sprinkler irrigated beans. Hort. Paraquat was less effective than Glyphosate to control weeds in citrons. In another trial, the handweeded control show the highest yield with sethoxydim (0.56 kg ai/ha) alone yielding second.Impacts(N/A)Publications, Progress 01/01/91 to 12/30/91OutputsNine field experiments were conducted to evaluate 10 herbicides in 7 crops. This was the first work It also was very good as a pre-emergent for coffee, but Linuron at 4 and 8#/A was best. Cyperus rotundus L. and Cynodon dactylon L. were controlled by Bay 94337. This experiment will be repeated. Lugo, M.de L., M. Diaz, H. Torres and C. Almodovar. Oxyfluorfen and simazine at 2 kg./ha. Correct answers: 2 question: In the world’s audience hall, the simple blade of grass sits on the same carpet with the sunbeam and the stars of midnight. No phytotoxicity was detected with sprinkler irrigation at the two sites; however, STG 3 caused 20 and 40% injury at three weeks with drip irrigation at Isabela and Juana Diaz, respectively. Good control in pigeon pea occurred with all Prometryn rates. The evaluation of living mulches in coffee showed that grass weeds were suppressed more in dalisgrass, carpet grass, Alexander grass, and pond peanut than in bahiagrass. In the corn-bean rotation, metolachlor as well as trifluralin and pendimethalin, both followed by bentazon plus sethoxydim, provided the best weed control after six weeks. and ACIN, N. 1997. Karmex 4 & 8# and mixture of Dowpon 3# + Karmex 2# gave good post weed control in ratoon cane. Atrazine was found to be safe for sweet corn even at rates of 8 lbs./A. PR. (3) Synbar 1 or 2 lb. Positive results were obtained with 1 and 2#/A Metribuzin in pigeon pea. In tanier, oxyfluorfen gave a better control of weeds than ametryn at the two rates tested (0.56 and 1.12 kg ai/ha). Glyphosate and paraquat are under evaluation for control of Brachiaria plantaginea, Paspalum urvillei and Digitaria sanguinalis.Impacts(N/A)Publications, Progress 01/01/84 to 12/30/84OutputsThe grass herbicides sethoxydim (Poast), fluazifop-butyl (Fusilade), and DPX-Y6202 (Assure) were evaluated in a primary screening on 9 vegetables and pigeon pea. Butachlor caused toxic effects. J. Agric.

Libro de Resumenes del XV Congreso de la Asociacion Latinoamericana de Malezas. As economically valuable as grasses are, the grass family, like all large plant families, also contains species that are considered pests or weeds and as such incur an economic cost. Data obtained this year in a Karmex-Sinbar combination experiment at Isabela were very erratic, duepossibly to heavy rainfall. Plastic mulch plus paraquat controlled 100 percent weeds in sweet potato, better than preeemergence ametryn, clomazone and dimethenamid followed by clethodim. J. Agric. A critical period of weed interference study on tanier has been continued into its second year. Team. C. J. Para grass is a warm climate grass that grows effectively at temperatures around 22°C and stops growing under 15°C. Suppresion of weeds by the living mulches may reduce the use of herbicide applications and potential contamination of chemicals in upland agroecosystems.Publications, Progress 01/01/02 to 12/31/02OutputsCompared with other weed species and a weed free control root nodule number, nodule fresh and dry weight of Phaseolus vulgaris was promoted by a nutrient solution applied to the root system of Echinochloa colona under greenhouse conditions.

New chemicals evaluated included propachlor, alachlor, pendimethalin and cyanazine. p.29 In: Abstracs Annual Meeting CFCS, Santo Domingo, Dominican Republic. Dowpon at 5 or 10#/A and Gramoxone alone or in combination with Karmex orAmetryne were the best post-emergence herbicides. Butachlor plus propanil showed good weed control in rice at Vega Baja. Dinosaurs have since gone extinct, while moss is still thriving! In pigeonpeas, imazethapyr at 0.056 to 0.224 kg ai/ha was again evaluated this year and continued showing promise as pre or early postemergence. Tenders & Procurement. Fewer applications of Glyphosate than of Gramoxone and Dowpon controlled the weeds in coffee. The minute wind-pollinated flowers are borne in small panicles (compound spikes) with three or four branches. In coffee, sulfosate (1.68 and 3.36 kg ai/ha) continued to give excellent weed control and produced good coffee berries equivalent to that of glyphosate treatment (2.24 kg/ha). Ametryne 4# was superior to Sencor in cwts Fluazifopbutyl provided excellent grass weed control seventeen weeks after treatment. This article was most recently revised and updated by, https://www.britannica.com/plant/carpet-grass. However, during the past few years this sector has also recovered in Afghanistan and there appears to be good potential for further expansion. Ametryne, Diuron, and Synbar were the most effectiveherbicides from the standpoint of weed control. Glyphosate at 2% gave excellent preemergence control of emerging weeds in yams and taniers. Both ppi rates of halosulfuron-methyl reduced A. dubius density but failed as postemergence treatment at 0.054 kg/ha. This was the first work Many pythons such as the carpet snake, amethystine python and children's python also have a series of labial pits on the sides of their lower jaws that can sense heat. Coffee: Trimming applied to living mulches (pond peanut and dalisgrass) every 4 to 12 months reduced weed cover after two year of mulch establishment. Oxyfluorfen applied 5 or 10 DAE reduced weed density more than the 15 DAE application. Coffee: Check plots without living mulch had more weeds than plots with the two living mulches Intercropping coffee and plantains reduced the weeds and the number of applications required. The control treatment, consisting of glyphosate application at an interval of every three to Round-up provided good weed control without toxic effects. This range of control is comparable to that of standard glyphosate treatment.

Poaceae (/ p oʊ ˈ eɪ s i aɪ /) or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses.It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. Ametryne was an effective preemg for taniers, but at high levels caused injuries. It is damaged by frost but not killed. In onions, postemergence application of oxyfluorfen at 0.125 kg ai/ha fluazifop-P at 0.42 kg ai/ha provided effective weed control and produced high yield. Weed cover was reduced more with trimming performed every 6 and 12 months than every 4 and 6 months. P.R. 90 (1-2). Mucuna was the best cover among four covers reducing nutsedge population at eight weeks. A plantain experiment established at Corozal is being harvested. Effect of herbicides on weeds and crops is being studied. One experiment was established by mid-December 2004 to evaluate purple nutsedge control with halosulfuron-methyl in calabaza.ImpactsSuppresion of weeds by living mulches may be used as an alternative practice to reduce the use of herbicide applications, thus reducing potential contamination of chemicals in upland agro-ecosystems. Ametryne was applied after planting, followedby postemergence applications of Gramoxone. Poaceae, grass family of monocotyledonous flowering plants, a division of the order Poales. Oxyfluorfen at 0.42 and 0.84 kg ai/ha, on the other hand, was highly phytotoxic and resulted in the lowest yield. Ametryne post 4# (a.i.) Weed control (42 days) was attained also by Karmex at 8#.
