Field experiments were conducted from 1989 to 1992 in Balcarce, Tandil, and San Cayetano, all in Buenos Aires province (Argentina), to evaluate clethodim, fenoxaprop-P-ethyl, fluazifop-P, haloxyfop, propaquizafop, and quizalofop-P-ethyl for bermudagrass control in sunflower, soybean, and potato. The highest levels of bermudagrass control 60 days after treatment (DAT) were generally obtained with fenoxaprop-P-ethyl, haloxyfop, propaquizafop, and quizalofop-P-ethyl. Late season bermudagrass control, based on biomass of stolons and rhizomes, suggested that the most consistent treatments in potato and sunflower were haloxyfop at 180 g ai/ha and quizalofop-P-ethyl at 54 g ai/ha. In soybean, clethodim at 336 g ai/ha, haloxyfop at 180 g/ha, propaquizafop at 100 g ai/ha, and quizalofop-P-ethyl at 54 g/ha provided the greatest reductions in bermudagrass biomass. All of the postemergence (POST) graminicide treatments increased crop yields when compared to a nontreated check. However, little or no difference in yield was obtained when herbicide rate was increased.

“…Common bermudagrass has been cited as one of the world's most troublesome weeds (8). Its viable seeds, rhizomes, and stolons are a major source for reproduction and spread (4,13). It has become a serious weed problem in many crops in the southern United States (7,11,12,15), and in Virginia, it is considered the most troublesome weed in peanut (20).…”

“…Such control measures are expensive and subsequent damage to the peanut plant can result in reduced crop yield (3). Furthermore, cultivation can spread rhizomes and stolons throughout the field in creasing future problems (13).…”

Field experiments conducted from 1990 through 1993 evaluated single and sequential applications of various postemergence graminicides for common bermudagrass control in peanut. UBI-1956 at 70 and 100 g/ha applied early POST (EP) or sequentially, controlled common bermudagrass equivalent to fluazifop-P applied EP or sequentially. Clethodim provided variable common bermudagrass control. Clethodim applied EP provided better control than sethoxydim while control from sequential clethodim applications were equivalent to fluazifop-P. Fenoxaprop-ethyl alone failed to control common bermudagrass while the addition of fluazifop-P to fenoxaprop-ethyl improved control at least 22% in two of three years. Quizalofop applied EP and fenoxaprop applied sequentially provided common bermudagrass control equivalent to fluazifop-P. Fenoxaprop-ethyl or sethoxydim applied once or twice controlled common bermudagrass similarly. Peanut yield increases from common bermudagrass control were erratic.

“…Apesar de ser considerada uma forrageira de qualidade e valor nutritivo, por apresentar elevado teor de proteína, digestibilidade da matéria seca, além do potencial produtivo (Pedreira & Tonato, 2007), é uma espécie que pode vir a ser problemática, sobretudo em áreas de cultivos agrícolas e produção de sementes de forrageiras de outras espécies, devido à sua fácil propagação e difícil erradicação (Mitich, 1989).…”

RESUMO -O Tifton 85 é uma forrageira de alto valor nutritivo, recomendada para pastejo, fenação e silagem, podendo ser considerada uma espécie daninha, principalmente em áreas de cultivos agrícolas e produção de sementes de outras forrageiras, devido a sua fácil propagação e seu rápido desenvolvimento. Este experimento foi proposto com o objetivo de avaliar a tolerância de plantas de Tifton 85 a doses crescentes de glyphosate em duas épocas diferentes. O experimento foi conduzido em vasos de polietileno com capacidade de 10 L, em delineamento experimental de blocos casualizados, no esquema fatorial 2 x 8, sendo duas épocas de aplicação (inverno e verão) e oito doses de glyphosate (0, 270, 540, 1.080, 2.160, 3.240, 4.320 e 5.400 g ha), com quatro repetições. Para cada época de aplicação, o controle das plantas de Tifton 85 foi feito aos 15, 30 e 60 DAA (dias após aplicação). Obteve-se controle superior a 90% de Tifton 85 a partir de 2.636,72 g ha -1 de glyphosate em aplicação realizada no inverno e de 3.607,03 g ha -1 em aplicação no verão. Os resultados evidenciaram a alta tolerância do Tifton 85 ao glyphosate e o maior controle das plantas expostas a esse herbicida em épocas mais frias do ano (inverno), quando em comparação com as plantas expostas ao herbicida no verão.Palavras-chave: Cynodon spp., pastagem, planta daninha, forrageiras.ABSTRACT -Tifton 85 is a type of forage of high nutritive value, recommended for grazing or hay and silage production. It can be considered a weed, mainly in agricultural and forage seed production areas, probably due to its easy propagation and fast development. Thus, this experiment aimed to evaluate Tifton 85 tolerance to increasing levels of glyphosate during two different seasons. The experiment was arranged in a completely randomized block design with four replications in a 2 x 8 factorial arrangement, and pulverization in two seasons (winter and summer) and eight glyphosate levels (0; 270; 540; 1,080; 2,160; 3,240; 4,320; and 5,400 g ha -1 ). The experiment was carried out in polyethylene pots with 10L capacity. For each season, control of the Tifton 85 plants was performed at 15, 30 and 60 DAA (days after application). Around 90% of Tifton 85 plant control was observed with 2,636.72 g ha -1 of glyphosate in the winter and 3,607.03 g ha -1 of glyphosate in the summer. The results obtained showed that Tifton 85 is highly tolerant to glyphosate and control is more efficient in the winter than in the summer.
