Past research efforts have been devoted to evaluating alternative weed control methods in specific crops of economic importance. Trifluralin at 0.88 kg ai/ha in sequential applications with fluazifop-p at 0.59 kg ai/ha was the best combination treatment on beans. Semidey, N., Gonzalez, A. and Aponte, A.. 1999. Evaluation of clomazone in arracacha and cassava. Slightly better control was obtained with quizalofop than with fluazifop at corresponding rates in both nursery and field trials. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Four factors have been identified to establish the importance of this sector for future … Sethoxydim (2%) provided good control of all grasses in taniers and cassava. The rise in economic opportunities meant that homeowners who were inclined to pursue a green carpet of grass could hire someone to attend to its needs—another indicator of success. Dowpon at 5 or 10#/A and Gramoxone alone or in combination with Karmex orAmetryne were the best post-emergence herbicides. all weeds in coffee. In two trials carried out at the Fortuna Substation, Sinbar applied at rates of 1, 2, 3 and 4 lb/A alone or combined with Karmex and Ametryne had no deleterious effects on Bermuda grass and nutgrass.Impacts(N/A)Publications, Progress 01/01/68 to 12/30/68OutputsThree experiments were established to evaluate the efficiency of various herbicides. Congress grass, Parthenium hysterophorus L., of the family Asteraceae (tribe: Heliantheae), is an erect and much branched annual or ephermeral herb, known for its notorious role as environmental, medical, and agricultural hazards. Updates? Cyperus rotundus L. and Cynodon dactylon L. were controlled by Bay 94337. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. In coffee, four native grasses and one introduced legume were evaluated as living mulches. Different application methods did not significantly affect the weed density and dry bean yield. Nutsedges (Cyperus spp.) (Chemisquy et al., 2010). Lugo, M. de L. y M. Diaz. Calabaza yields were not affected by herbicide treatments. Poaceae, grass family of monocotyledonous flowering plants, a division of the order Poales. Another experiment was established at this same Station. Diphenamid at10 lbs and Diphenamid at 4 lbs + Amiben at 6 lbs/A gave best weed control in sweet potatoes. Paraquat applied either once or twice gave excellent weed control but caused 20% crop phytotoxicity with the second application. ... based solely on economic values derived from … sugar/A at Isabela and % sucrose at Lajas. Paraquat at 2 pt/A applied monthly provided excellent weed control in young sun-grown coffee. 2000. P.R. After ensuring technical feasibility and economic viability, the scheme is sanctioned by the bank. LUGO, M. de L., ORENGO, E. y ACIN, N. 1998. 2.24 kg ai/ha handweedings produced high yields. Highest edible root yield was obtained with 3 applications of paraquat at 2.34 1/ha rate to cassava at Isabela. Trophy It is the arrangement of colourful potted plants in differ­ent tiers around a central object which may be a tree trunk, lamp post or a pillar. The critical period of weed competition in Rosita eggplant was established at 28 days after transplanting and for Borinquen pumpkin at 21 and 35 days at Juana Diaz and Lajas, respectively. at 0.56 and sethoxydim at 0.34 kg ai/ha produced 84% and 80% weed control, respectively, three weeks after herbicide application. Some pasture rehabilitation strategies can be relatively simple and cost-effective. Phytotoxicity was observed only at 4X rate. Weed control was improved at a higher rate (6.72 kg ai/ha) but with slight crop injury that did not affect significantly the tuber yield. Elephant grass can be grazed, provided it can be kept at the lush vegetative stage: livestock tend to feed only the younger leaves . LAWN WITH SHADE GRASS . Sweetcorn was affected. controlled the renewal. Ametryne & Prometryne were the least injurious. Best results were obtained with preemergent and postemergent (pre &post) herbicides in 12 crops, as follows: Pre - pigeon pea, Metribuzin at .5# & Chloramben at 3#; eggplant, Bifenox at 1.5#; pepper, Hercules 22234 at 3#; tomato, Metribuzin at 1#; okra, Gulf S-6796 at 4#; corn, Bifenox at 1.5#; lettuce, Pronomide at 3#. In rice, sequential application of propanil at 3.36 kg ai/ha and cinmethylin at 50 g/ha gave excellent weed control and produced the highest grain yield (3,165 kg/ha). The cleaning industry is also one of the most recession-proof industries out there! But, you man of riches, your wealth has no part in the simple grandeur of the sun’s … In pigeon peas, prometryn (4,48 kg ai/ha) and metribuzin (1.50 kg ai/ha) caused low to moderate injury to five pigeon pea cultivars three weeks after herbicide treatments. West Indian cherries treated with paraquat and dalapon were collected for residue analyses at Naguabo. Fluazifopbutyl provided excellent grass weed control seventeen weeks after treatment. As living mulches increased ground cover, more weeds were suppressed in coffee plantation. The highest pumpkin yield was obtained with the integration of chloramben at 3.0 kg ai/ha, mechanical cultivation and hand weeding. Diphenamid 5# pre or Amiben pre or post 2# gave the best weed control in tobacco. No significant differences in number and weight of plantains were measured when paraquat was applied at 2.34 l/ha and glyphosate at 1% either under tilled on non-tilled conditions. These two weed species actually constitute the two most pressing weed problems in our sugarcane fields. Oxyfluorfen (Goal) was effective and was not toxic in coffee and Napropamide was inferior. P.R. Paraquat was a good leaf desiccant. 1117 seemed to more susceptible to Synbar and Diuron than the P.R. Economic Importance (Back to Top) Turfgrass (sod) production is an important industry in the United States covering more than 25 million hectares, and Florida is one of the main sod producing states cultivating an estimated 37,635 ha and harvesting over 25,495 ha annually (Haydu et al. Metribuzin at 0.85 kg/ha produced pigeon pea yields similar to the hand-weeded plots. For example, in 1989 the Tisman Plantation on Malekula, Vanuatu, seeded glycine into strips of carpet grass infested with wild tobacco weed. Some of the more important families are the Palmaceae, Gramineae, Liliaceae, Musaceae, Amaryllidaceae, Malvaceae, Urticaceae, Linaceae, Moraceae, Tiliaceae, Bromeliaceae, Bombacaceae, and Luguminosae. Chloramben and Alachlor were the best for pumpkins and dry beans. Semidey, N. and L. E. Flores. four months resulted in the highest soil loss of all treatments. They seed profusely. were An experiment for the evaluation of Sinbar and Karmex established at Fortuna will be harvested during the 1970 harvest season. Sethoxydim and trifluralin treatments yielded more than 370 kg/ha of green-shelled beans. Overall, transplanted calabaza produced higher yield (15, 290 kg/ha) than direct seeded calabaza (4, 190 kg/ha). Maximum leaf area index (LAI) of A. dubius occurred before maximum LAI of sweet potato. By 1990, the glycine had smothered the weed and had raised growth rates from 250 kg LWG/ha/yr to 500 … WP at 0.75# ai/A gave bestresults in pre and postemergence applications. The root injury reduces the turf's ability to take up water and nutrients and withstand the stress of hot, dry weather conditions. Mucuna, pigeon pea, grain sorghum, and calabaza, which were grown as cover crops for six months and later incorporated into the soil before planting onion, reduced purple nutsedge density 37% more than that of open plots without cover crops. The best herbicide for weed control in taniers at Isabela was Prometryne. This result indicates that calabaza, when transplanted, may compete better against weeds than when direct Field studies were conducted to determine critical period of weed interference in arracacha and tanier and data analysis is in progress. They rank among the top five families of flowering plants in terms of the number of species, but they are clearly the most abundant and Paraquat was evaluated in tomatoes and sweet peppers at Lajas. This was the first work In bean, imazethapyr was evaluated according to the methods of application (preplant incorporated, preemergence, and postemergence). In green beans, fluazifop-p at 0.56 kg ai/ha effectively controlled perennial grasses up to 56 days after planting. Herbicides controlled weeds effectively and did not affect eggplant nor cabbage, which produced acceptable yields. P.R. Cortada was the cultivar most tolerant to all three herbicides.Impacts(N/A)Publications, Progress 01/01/96 to 12/30/96OutputsNine field experiments were conducted to evaluate herbicide efficacy or weed interference in six crops.

This type of massive root structure creates a dense net that develops a sod layer anchoring plants to importance of S. frugiperda has been widely repor- ... Axonopus fissifolius Raddi Kuhlm. In contrast to bean, corn in rotation with bean produced yields as high as in the first corn planting. Turf is damaged when the grubs (the larval or immature stages of certain beetles) chew off the grass roots just below the soil surface. Dowpon controlled narrowleaf weeds, but not broadleaves. Morrone was proposed in 2010 as a replacement for Pennisetum purpureum Schumach. created by carpet weaving centres coming up in Pakistan where Afghan refugees have introduced it. In a herbicide screening experiment on taniers imazethapyr (0.14 kg ai/ha) gave the best weed control of the six herbicides. Local Economic Plan. Semidey, N. 2002. Data on residues are also being collected. 2004. Rice: Propanil alone and in mixtures is still the best treatment. Preemergence Bifonox plus Bentazon postemergence ranked third. Basic Grains: Grass weeds were significantly reduced by preemergence metolachlor and atrazine, and postemergence sethoxydim during first six weeks. 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. San Juan, P.R. Treflan, 1.0 lb best preemerge in okra. Data obtained this year in a Karmex-Sinbar combination experiment at Isabela were very erratic, duepossibly to heavy rainfall. Total weed density was not affected by the two living mulches for the first five months of coffee establishment. In coffee, a living mulch experiment using four native grasses and one introduced legume was initiated. Field experiments are in progress to determine plant nutrient competition in sweet potato, weed management strategies in tanier and to evaluate efficacy and phytotoxicity of sethoxydium in arracacha.Impacts(N/A)Publications, Progress 01/01/97 to 12/01/97OutputsSeven field experiments were conducted to evaluate eight herbicides and a mulching practice in five tropical crops during the past year. The taxon Cenchrus purpureus (Schumach.) There were no yield differences among herbicide treatments at Gurabo. At Juana Diaz, STG 1 provided the best yield of dry beans (1,160 kg/ha). Annual Meeting of the Caribbean Food Crops Society. In tuber and root crops, the average clomazone treatment produced 64%, 70%, 107% and 108% of the handweeded control for yams, taniers, cassava and arracacha, respectively. Pre-emergentes en yautia. LUGO, M. DE L., and SANTIAGO, L.R. In an interview with PuroClean, a restoration and sanitation company, the business highlights that workers in the company are seen as community heroes for the vital role they play - when everything is hunky-dory, and even more so during times of … A tanier experiment was established in 1999 with ametryn, oxyfluorfen, imazethapyn, paraquat, glyphosate, and sethoxydim as treatments. 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. 2. Lugo, M. de L. and Acosta, A. 2000. In coriander and spiny coriander experiments, oxyfluorfen (0.13 & 0.26 kg ai/ha) and sethoxydim (0.22 & 0.44 kg ai/ha) gave the best weed control and produced intermediate yields. Bromacil, at 3#, was effective for a 4-month period.Impacts(N/A)Publications, Progress 01/01/74 to 12/30/74OutputsPaspalum fasciculatum was effectively controlled by Round-up 3-6 lbs/A (#) & Dowpon 10#. The advantage of using closely spaced plantains to provide shade to young coffee was further demonstrated. Positive results were obtained with 1 and 2#/A Metribuzin in pigeon pea. The grass grade is the least expensive of the outdoor carpets. 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. Harvested plants declined at the rate of 185 plants for each week of interference. Best results were obtained when both were combined in a singleapplication. A lawn is an area of soil-covered land planted with grasses and other durable plants such as clover which are maintained at a short height with a lawnmower (or sometimes grazing animals) and used for aesthetic and recreational purposes. compared favorably in weed control with hand weeded tanniers or when combined with post herbicide applications. Pre- and postemergent herbicide evaluation in 24 sugarcane varieties showed that best preemergent treatment was Metribuzin (2.24, 3.36 kg/ha) followed by Velpar (2.24) and Terbacil. Control de malezas y erosion de suelo en cafe con cobertoras vivas en la zona alta de Puerto Rico. The control treatment, consisting of glyphosate application at an interval of every three to 37:43-44. Mucuna was the best cover among four covers reducing nutsedge population at eight weeks. Coffee: Check plots without living mulch had more weeds than plots with the two living mulches There were no significant differences in green-shelled beans at the two sites using drip irrigation. Treated plots yielded similar results as cultivated plots. Pineapples: Both paraquat and glyphosate were excellent in controlling weeds and increasing crop yields. Application timing for oxyfluorfen at 10 days after onion emergence reduced early weed infestation 89% more than conventional application at 15 DAE.Publications, Progress 01/01/03 to 12/31/03OutputsSweetpotato yield was improved with preemengence clomazone compared to the yield with a plastic mulch + paraquat treatment at Juana Diaz. The cleaning industry is also one of the most recession-proof industries out there! Oxyfluorfen was safe and effective for weed suppression in onion. ... of Economic Entomology 109: 125–1131. It yields a stiff fibre used in making rope and various other products. In sweet cherry peppers, the integrated plastic mulching + paraquat (0.56 kg ai/ha) significantly outyielded preplant and postemergence applications of either glyphosate (1 and 2%) or paraquat (0.56 kg ai/ha) treatments. and ACIN, N. 1997. Hand hoeing, hoeing + hilling-up and Diphenamid at 6#/Apost + hilling were the best treatments for weed control in field grown tobacco.Venezuela grass was effectivelyImpacts(N/A)Publications, Progress 01/01/75 to 12/30/75OutputsGlyphosate, Velpar, and RH-2915 in postemergent (post) applications at 3.1, 4.0 and 4.0 kg/ha, respectively, were the best herbicides for controlling Paspalum fasciculatum. In arracacha, sethoxydim, applied either once or twice, gave good grass control. The minute wind-pollinated flowers are borne in small panicles (compound spikes) with three or four branches. Snakes can swallow food larger than their heads. Congress grass, Parthenium hysterophorus L., of the family Asteraceae (tribe: Heliantheae), is an erect and much branched annual or ephermeral herb, known for its notorious role as environmental, medical, and agricultural hazards.
