“…Chemical weed control is one of the methods used to control weeds in DSR, but due to concerns about the development of resistance and an insufficiency of new and effective herbicides, there is a need to integrate other weed management strategies along with chemical control (Chahal et al, 2014(Chahal et al, , 2015. Because of the variability in the growth habit of weeds, no single method of weed control can provide effective and season-long control in DSR (Aulakh et al, 2013).…”

-Weed management is a primary concern in direct seeded rice (DSR) cropping because weed growth becomes a major constraint on crop yield. A two year field study was set up to evaluate the effect of various weed control measures on crop growth, grain yield and grain quality of DSR. The experiment involved five different weed control measures: hand weeding, hoeing, inter-row tine cultivation, inter-row spike hoeing and herbicide treatment (Nominee 100 SC). The extent of weed control (compared to a non-weeded control) ranged from 50-95%. The highest crop yield was obtained using hand weeding. Hand weeding, tine cultivation and herbicide treatment raised the number of fertile rice tillers formed per unit area and the thousand grain weight. Tine cultivation provided an effective and economical level of weed control in the DSR crop.Keywords: herbicides, direct seeded rice, grain yield, tine cultivator.

“…Higher rates (≥ 2,480 g ae ha -1 ) were required to achieve 90% control of 20-cm tall common waterhemp plants. Several studies have reported that the height of weed species at the time of POST herbicide application is an important factor determining the level of control achieved (Chahal et al, 2014;Cordes et al, 2004;Craigmyle et al, 2013b). …”

With the intent to control glyphosate-resistant and hard to control weeds, a formulation of 2,4-D choline (24.4%) and glyphosate (22.1%) (Enlist Duo™ herbicide) (Note 1) has been developed recently to be used post-emergence in corn and soybean tolerant to Enlist Duo™ in the United States. Dose response studies were conducted under greenhouse conditions for the evaluation of effective rates of Enlist Duo™ to control glyphosate-resistant common waterhemp (Amaranths rudis Sauer), giant ragweed (Ambrosia trifida L.), and kochia [Kochia scoparia (L.) Schrad] and to determine the effect of growth stage of these weeds on the efficacy of Enlist Duo™. Three parameter log-logistic models were used to develop dose response curves. Glyphosate-resistant giant ragweed was the most sensitive of the three weed species, followed by common waterhemp, and kochia. Based on the visual control or injury estimates, the Enlist Duo™ rates required for 90% control (ED 90 ) of common waterhemp, giant ragweed, and kochia were 1179, 825, and 4,382 g ae ha -1 , respectively, for 10-cm tall plants compared to 2,480, 1,101, and 5,305 g ae ha -1 , respectively, for 20-cm tall plants at 21 days after treatment (DAT). The ED 90 values calculated on the basis of percent shoot biomass reduction and visual control or injury estimates were usually similar at 21 DAT. The greenhouse studies indicate that Enlist Duo™ can effectively control less than or equal to 20-cm tall glyphosate-resistant giant ragweed and less than or equal to 10-cm tall glyphosate-resistant common waterhemp at the recommended rate (1,640 g ae ha -1 ).

“…The association between chlorimuronethyl with other molecules, highlighting glyphosate, was recently studied by many authors, among who are Albrecht et al (2012), Oliveira Neto et al (2013), Chahal et al (2014) and Belfry et al (2015). These studies were directed especially for difficult to control weed management, and also to the selectivity of this association for soybean crops.…”

-The aim of this study was to evaluate the selectivity of ALS inhibitor herbicides, applied isolated and associated with glyphosate in post-emergence of soybean cultivar presenting the RR/STS technologies. The experimental design was a randomized block with four replications and ten treatments. The treatments consisted of the application of glyphosate and ALS inhibitors herbicides, isolated and associated with glyphosate. The application of treatments occurred in V4 stage of plant development. The evaluation of phytointoxication, SPAD index was conducted, as well as variables related to agronomic performance (height, number of pods per plant, yield and mass of a thousand seeds). Yet additional test with the same cultivar and treatment was conducted in a greenhouse in a completely randomized design with four replications. Soybean cultivar CD 2630 RR/STS presented itself tolerant to application in post-emergence herbicides used alone or combined with glyphosate. Except to metsulfuron-methyl (2.4 g a.i. ha -1 ), associated or not with glyphosate (960 g a.e. ha -1 ).Keywords: sulfonylurea tolerant soybeans, phytointoxication, chemical management, Glycine max.

RESUMO -O objetivo do presente trabalho foi avaliar a seletividade de herbicidas inibidores da ALS, aplicados isoladamente e associados com glyphosate, em pós-emergência de cultivar de soja contendo as tecnologias RR/STS. O delineamento experimental foi de blocos casualizados, com quatro repetições e dez tratamentos. Os tratamentos foram constituídos da aplicação de glyphosate e herbicidas inibidores da ALS, isolados e associados com glyphosate. A aplicação dos tratamentos
