| ABSTRACT: Phytosociological studies are extremely important for the management of weeds in cultivated areas. Thus, the goal of this work was to evaluate the interference of mineral oil associated with oxyfluorfen and flumioxazin, through the phytosociological survey of weeds. Therefore, this experiment was conducted in a 2 x 5 + 1 factorial design and with four replications; the following oxyfluorfen + flumioxazin associations were evaluated: 240 + 50, 192 + 40, 144 + 30, 96 + 20 and 48 + 10 g a.i. ha-1, with and without the addition of mineral oil, including a control sample without application. Thirty days after the application, plant density, frequency and abundance of species were determined, and so were frequency, density and relative abundance, as... |

| ABSTRACT This study aimed to evaluate the control of Rottboelia spp. with the formulated mixture diuron + hexazinone + sulfometuron-methyl and the emergence of this weed in the months of April, May, June, July, August, September, October and November 2012 in sugarcane cultivation, cultivar RB867515. The experimental design consisted of randomized blocks, with treatments in a 4 x 4 factorial arrangement with four replicates for the months of April to November. The emergence tests used a randomized block design, in a 8 x 5 split plot arrangement with four replicates. The analyzed factors were the rates of the formulated mixture (diuron + hexazinone + sulfometuron-methyl), which consisted of: 1,809.00 + 510.00 + 43.50 g ha-1 (T2); 1,507.50 + 425.00 + 36.25 g... |

| ABSTRACT: Atrazine is selective for maize, sugarcane and sorghum and may interfere with successor crops such as sunflower and soybean. Despite this problem, there are few studies about the residual effect of this herbicide in these crops. Thus, the objective of the research was to evaluate the residual effect of atrazine through bioavailability of the herbicide in sandy and clayey soils, using soybean and sunflower as bioindicators. The design was completely randomized with four replications and a 2 × 7 + 1 factorial scheme, that is, two doses (2,000 and 2,500 g ha-1), seven application times (0, 15, 30, 45, 60, 75 and 90 days between application (DBA) of herbicide and bioindicator sowing) and one control without application. Dry mass and chlorophyll... |
