Effect of Mesotrione and Nicosulfuron Mixtures With or Without Adjuvants Planta Daninha
DUUS,J.; KRUSE,N.D.; STREIBIG,J.C..
ABSTRACT: In Field experiments, a logarithmic sprayer was used to screen the efficacy of 28.5% mixture of nicosulfuron and mesotrione, and the herbicides applied separately. Three adjuvants were also used to assess how they affected the potency of the mixture. The objectives were to test whether a mixture was enhancing or detracting the effect relative to ADM (Additive Dose Model). The test plants were canola and barley. The 28.5% nicosulfuron mixture was acting antagonistic, irrespective of plant species. The antagonistic effect of the nicosulfuron mixture decreased the more developed the plants became; for barley, it almost disappeared 40 days after treatment. For both canola and barley, one adjuvant stood out as being highly effective in decreasing ED50...

Electrolyte Leakage and the Protective Effect of Nitric Oxide on Leaves of Flooded Rice Exposed to Herbicides Planta Daninha
SILVA,K.S.; URBAN,L.J. K.; BALBINOT,A.; GNOCATO,F.S.; KRUSE,N.D.; MARCHESAN,E.; MACHADO,S.L.O..
ABSTRACT The nitric oxide acts on the antioxidant system of plants and can discontinue the damage of herbicides elicitors of oxidative stress that cause the disruption of membranes and leakage of cellular contents. In order to evaluate the protective effect of nitric oxide in electrolytes leakage, leaf segments of the Puita INTA CL rice cultivar were incubated with 0, 5, 50, 500 and 5,000 μM clomazone (360 g a.i. L-1), oxadiazon (250 g a.i. L-1), oxyfluorfen (240 g a.i. L-1) and the formulated mixture of paraquat (200 g a.i. L-1) + diuron (100 g a.i. L-1) to obtain the maximum potential conductivity of 50% (MPC50). Subsequently, leaf segments were pre-treated with 0, 200 and 2,000 μM of sodium nitroprusside (SNP) for four hours and further incubated for 48...

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 Morning Glory in Soybean Yield Planta Daninha
PICCININI,F.; MACHADO,S.L.O.; MARTIN,T.N.; KRUSE,N.D.; BALBINOT,A.; GUARESCHI,A..
ABSTRACT: Weed control using herbicides with the same mechanism of action can encourage the emergence of resistant biotypes or tolerant plants. An example of this is the occurrence of morning-glory (Ipomoea sp.) in soybean crops in southern Brazil. In this sense, the aim of this study was to quantify the losses arising from two species of morning-glory weeding coexisting with soybean crop. A field study was conducted in the 2013/2014 season. The experimental design was a randomized block with four replications, with treatments being distributed in a factorial arrangement (2x2x5), which assessed the effect of competition on two soybean cultivars (TEC6029 and TEC7849) of morning-glory species (I. triloba and I. purpurea) in different population (0, 4, 8, 16...

Soybeans Competitiveness with Morning Glory Planta Daninha
PICCININI,F.; MARTIN,T.N.; MACHADO,S.L.O.; KRUSE,N.D.; SCHMATZ,R..
Weeds interfere negatively on development, yield and quality of soybeans (Glycine max). Inadequate weed control by herbicide use can select for resistant or tolerant biotypes, leading to a shift in the weed flora. An example is the increase of incidence of morning glory (Ipomoea spp.) in soybeans growing areas in South Brazil. The aim of this study was to determine the competitiveness of soybeans intercropped with I. triloba, I. indivisa and I. purpurea through a replacement experiments series. Greenhouse experiments were conducted in a completely randomized design with four replications. The first experiment was carried out aiming to get the plant population while total plant dry mass remained constant. Other experiments were done under replacement series...
