Bioassay for Determining Persistence of the Herbicide Saflufenacil in an Oxisol Planta Daninha
DIESEL,F.; TREZZI,M.M.; VIDAL,R.A.; BARANCELLI,M.V.J.; MIZERSKI,P.H.F..
ABSTRACT: Persistence of an herbicide is defined as the ability to maintain the integrity of its molecule and chemical, physical, and phytotoxic properties in the environment where it was applied. Knowledge of persistence has implications both for the toxicity generated on species grown in succession and for the period in which the herbicide controls weeds. This study aimed to assess the persistence of the herbicide saflufenacil in an Oxisol by means of bioassays. Two experiments with the application of 29.4 g ha-1 of saflufenacil were carried out under field conditions: the first in the 2011/2012 season and the second in the 2012/2013 season. Soil samples were collected at depths of up to 10 cm at different times after application. Subsequently, two...

Interaction Between Saflufenacil and Other Oxidative Stress Promoting Herbicides to Control Wild Poinsettia Planta Daninha
DIESEL,F.; VIECELLI,M.; TREZZI,M.M.; PAGNONCELLI JR.,F.B..
ABSTRACT: Synergism is a desired result in the interaction between herbicides because it provides many benefits, among which the reduction of doses and the increment of control efficiency, and because it positively signals for the joint application of herbicides. The objective of this study is to evaluate the effect of the association of saflufenacil with other herbicides that promote oxidative stress on the development of Euphorbia heterophylla as well as to analyze if the resulting interactions are antagonistic, additive or synergistic. The experiment was conducted in pots, in a greenhouse, using a completely randomized design with four replications. Treatments consisted of saflufenacil (0, 1,2, 2,32, 4,47, 8,63, 16,65 g ha-1) alone and associated with...

Interactions of Saflufenacil with Other Herbicides Promoters of Oxidative Stress to Control Joyweed1 Planta Daninha
TREZZI,M.M.; DIESEL,F.; KRUSE,N.D.; XAVIER,E.; PAZUCH,D.; PAGNONCELLI JR.,F.; BATISTEL,S.C..
ABSTRACT This study was conducted to evaluate the efficacy of joyweed (Alternanthera tenella) control and antagonistic or synergistic potentials of saflufenacil herbicide applied alone or tank mixed with paraquat, metribuzin and clomazone. The experiment was conducted in a greenhouse in a completely randomized design with four replications. Treatments consisted of saflufenacil herbicide doses (0, 0.4, 0.7, 1.4, 2.1 and 2.8 g ha-1) applied isolated or associated with paraquat (0, 1 and 3 g ha-1), metribuzin (0, 38.4 and 105.6 g ha-1) or clomazone (0, 288 and 504 g ha-1). Visual control was determined at 14 and 21 days after spraying the herbicides (DAA) and shoots dry matter at 21 DAA. Colby's method was used to calculate the response from herbicide...

Interference of Broadleaf Buttonweed and White-Eye in Soybean Planta Daninha
DIESEL,F.; TREZZI,M.M.; GALLON,M.; MIZERSKI,P.H.F.; BATISTEL,S.C.; PAGNONCELLI,F.B..
ABSTRACT: Weed species is one of the factors contributing to grain yield losses due to crop-weed competition. Two of the most common weeds of soybean fields in Brazil are from the Rubiaceae family: Borreria latifolia and Richardia brasiliensis. This study aimed to evaluate the effects of B. latifolia and R. brasiliensis on plant development, yield components, and soybean productivity. Two assays were conducted in a randomized block design with four replications, using a two-level factorial design, in which the first factor consisted of the species B. latifolia and R. brasiliensis and the second factor consisted of the densities 0, 2, 4, 6, 8, 10, and 12 plants m-2. Plant height, leaf area and total chlorophyll in the V6 and R5 stages, number of pods per...

Tolerance to Glyphosate in Broadleaf Buttonweed and White-Eye Biotypes Planta Daninha
DIESEL,F.; TREZZI,M.M.; GALLON,M.; BALBINOT JR.,A.A.; PAGNONCELLI,F.B..
ABSTRACT: Infesting species of Rubiaceae family have great importance in soybean crops in Southwest of Paraná and North of Santa Catarina, especially due to the selection of tolerant populations caused by the pressure of selection exerted by intensive use of glyphosate. The study aimed to evaluate the levels of tolerance to glyphosate in biotypes of broadleaf buttonweed (Borreria latifolia) (BL) and white-eye (Richardia brasiliensis) (RB) by means of dose-response curves. Two experiments were conducted in a greenhouse, in completely randomized design (CRD), with four replications. Fourteen BL biotypes and eleven RB biotypes were evaluated, collected in soybean fields of Paraná and Santa Catarina. The doses of glyphosate were 0, 74, 163, 360, 792 and 1,742...
