“…Even with the appreciation of landscape works, research papers dealing with grass species are still incipient and the available information is more concentrated in the management of fertilization (GODOY et al, 2007). Information about the selectivity of herbicides is incipient because lawns have no agricultural importance, and concern about the selectivity of herbicides is in the background (MCELROY;MARTINS, 2013).…”

“…Bentazon, nicosulfuron, halosulfuron, oxadiazon and 2.4-D are examples of herbicides registered and used on lawn areas in countries, such as in the United States (GROSSMAN, 2009;BROSNAN et al, 2010;BHOWMIK, 2012;MCELROY;MARTINS, 2013). Maciel et al (2011) consider the use of selective herbicides and also promote the suppression of growth without sacrificing the visual quality of lawns.…”

The aim of this work was to evaluate the selectivity of herbicides applied in post-emergence on Zoysia japonica Steud (Poaceae) and determine associations with the leaf anatomy of this grass. The experimental design was randomized blocks with four replications. The treatments were the application of the herbicides bentazon (720 g ha -1 ), nicosulfuron (50 g ha -1 ), halosulfuron (112.5 g ha -1 ), oxadiazon (875 g ha -1 ) and 2.4-D (698 g ha -1 ), plus a control treatment without herbicide application. Phytotoxicity was assessed every seven days after application (DAA) of the herbicides until the symptoms disappeared. Foliar anatomical analyses of the leaves in the collected grass were conducted until the 35 th DAA. The quantitative characters of the keel and wing region of the blade of Z. japonica were assessed, as well as the biometric characters, which were submitted to an analysis of variance F test, and the averages were compared by Tukey's test at a probability of 5%. The values of the anatomical characters of the foliar blade were tested by cluster analysis. The application of herbicides did not negatively influence the height of the plants but did reduce their dry mass. Toxic symptoms disappeared after 21 DAA, with the only symptoms of injury observed in plants treated with the herbicides oxadiazon and nicosulfuron. In addition, the cluster analysis indicated the formation of a unique discriminatory group. Thus, the results show that the herbicides applied to Z. japonica were selective for the species.

ResumoObjetivou-se com esse trabalho avaliar a seletividade de herbicidas aplicados em pós-emergência sobre grama Esmeralda -Zoysia japonica Steud (Poaceae), em associação com estudos da anatomia foliar dessa grama. O delineamento experimental foi em blocos ao acaso, com quatro repetições. Os tratamentos constituíram da aplicação dos herbicidas: bentazon (720 g ha -1 ), nicosulfuron (50 g ha -1 ), halosulfuron (112,5 g ha -1 ), oxadiazon (875 g ha -1 ) e 2,4-D (698 g ha -1 ), além de um tratamento controle, sem aplicação de herbicidas. As avaliações de fitointoxicação foram realizadas a cada sete dias após a aplicação dos herbicidas (DAA) até o desaparecimento dos sintomas. Realizaram-se análises anatômicas foliares da grama coletando-se folhas no 35 o DAA. Avaliaram-se os caracteres quantitativos da região da quilha e da asa do limbo de Z. japonica, bem como os caracteres biométricos da grama, os quais foram

“…The aesthetic value is defined by its beauty and the value the garden adds to the scenery. In addition, the usability is the durability of a given field to sports or reduction in the erosion effects (McElroy and Martins, 2013), due its unique characteristics such as fast growth, deep and penetrating root system, and high tolerance to adverse conditions (Xiao et al, 2011).…”

Weed infestations and the few post-emergent control alternatives available are some of the main problems in the management of ornamental and sports lawns. Given the exposed, the study aims to evaluate the selectivity of five herbicides to four grass varieties: Paspalum notatum (bahia grass), Cynodon dactylon (bahama grass-ITG6), Zoysia japonica (japanese lawn grass) and Zoysia japonica (imperial -ITG5), as well as the control efficiency of those upon nutsedge (Cyperus rotundus) and sudan grass (Urochloa decumbens). The following herbicides were applied in the recommended doses: sulfentrazone + diuron, isoxaflutole, triclopyr, 2,4-D and halosulfuron. Visual phytotoxicity symptoms in turfgrass and weed control were performed at 7, 14, 21, 28, 35 and 42 days after herbicide application and, at the end of the evaluations, was quantified the dry weight. The herbicides sulfentrazone + diuron and isoxaflutole were not selective to any turfgrass, although sulfentrazone + diuron controlled C. rotundus and U. decumbens species and isoxaflutole controlled only U. decumbens. However, halosulfuron and 2,4-D herbicides were selective to all of grasses and promoted weed species control. The herbicide triclopyr was selective to P. notatum, Z. japonica and Z. japonica-ITG5, and it can be used to control C. rotundus and U. decumbens.

To understand the observed injury, the objectives of this research were (a) to correlate combination of nitrogen fertilization and metsulfuron [methyl 2-(4-methoxy-6-methyl-1,3,5-triazine-2-ylcarbamoylsulfamoyl) benzoate] with excessive injury to centipedegrass [Eremochloa ophiuroides (Munro) Hack.] and (b) to determine how simultaneous high nitrogen fertilizer and the resulting increased metsulfuron rates exacerbated the observed injury. Field research was conducted
