“…Saflufenacil phytotoxicity decreased at the other sowing times; however, even at 60 DAA, phytotoxicity close to 40% was observed for the commercial dose, which could lead to yield losses. These results corroborate those of Brighenti (2015), who reported that saflufenacil decreased the plant stand and sunflower yield (kg ha -1 ), with the highest dose also reducing the weight of 1000 achenes. Peanut plants presented a phytotoxicity below 20% only at 60 DAA, with their highest phytotoxicity (40%) observed at 0 DAA ( Figure 2D).…”

The herbicides saflufenacil and indaziflam have recently been registered in Brazil for weed control in sugarcane crops; however, little information exists regarding their residual effects or influences on soil microorganisms. Therefore, the present study aimed: (a) to determine the effects of saflufenacil and indaziflam on soil microorganisms and (b) to evaluate the residual and dose effects of these herbicides on soybean, sunflower, sunn hemp and peanut crops. The herbicides indaziflam (100 g a.i. ha

“…Soltani et al (2019) reported that halosulfuron applied early POST provided 90% control of GR soybean volunteers in white bean (Phaseolus vulgaris L.) in field studies conducted in Ontario, Canada. Brighenti (2015) reported that volunteer soybean can be a problem weed in sunflower (Helianthus annuus L.) grown in rotation in Brazil, with no selective herbicide available for effective control without sunflower injury.…”

Since the commercialization of herbicide-resistant (HR) crops, primarily glyphosate-resistant (GR) crops, their adoption increased rapidly. Multiple HR traits in crops such as canola (Brassica napus L.), corn (Zea mays L.), cotton (Gossypium hirsutum L.), and soybean [Glycine max (L.) Merr.] are available in recent years, and management of their volunteers need attention to prevent interference and yield loss in rotational crops. The objectives of this review were to summarize HR crop traits in barley (Hordeum vulgare L.), canola, corn, cotton, rice (Oryza sativa L.), soybean, sugarbeet (Beta vulgaris L.), and wheat (Triticum aestivum L.); assess their potential for volunteerism; and review existing literature on the interference of HR crop volunteers, yield loss, and their management in rotational crops. Herbicide-resistant crop volunteers are problem weeds in agronomic cropping systems, and the impact of volunteerism depends on several factors such as crop grown in rotation, the density of volunteers, management practices, and micro-climate. Interference of imidazolinone-resistant (IR) barley or wheat volunteers can be a problem in rotational crops, particularly when IR crops such as canola or wheat are grown. Herbicide-resistant canola volunteers are abundant in the Northern Great Plains due to high fecundity, seed loss before or during harvest, secondary seed dormancy, and can interfere in crops grown in rotation such as flax (Linum usitatissimum L.), field peas (Pisum sativum L.), and soybean. Herbicide-resistant corn volunteers are competitive in crops grown in rotation such as corn, cotton, soybean, and sugarbeet, with yield loss depending on the density of HR corn volunteers. Volunteers of HR cotton, rice, soybean, and sugarbeet are not major concerns and can be controlled with existing herbicides. Herbicide options would be limited if the crop volunteers are multiple HR; therefore, a record-keeping of cultivar planted the previous year and selecting herbicide is important. The increasing use of 2,4-D, dicamba, glufosinate, and glyphosate in North American cropping systems requires research on herbicide interactions and alternative herbicides or methods for controlling multiple HR crop volunteers.

“…Other post-emergent herbicides have been reported to be effective in controlling volunteer soybeans such as diquat, paraquat, paraquat + diuron, 2,4-D, atrazine (Dan et al, 2009 andLima et al, 2011 andConcenço, 2014), ametryn and glufosinate-ammonium (Brighenti, 2015). However, for the castor there are studies indicating only viability of 2,4-D associated with glyphosate in the desiccation prior to sowing and paraquat + diquat in a Means followed by the same letter in the column does not differ significantly from each other by Tukey test (p ≤ 0.05).…”

Castor bean is an alternative to many grain production areas, mainly as crop for the second season after soybean. In this scenario, there is demand for research on management of plants, resulting from remaining seeds of soybean after harvest. The objective of this work was to evaluate the selectivity and efficacy of post-emergence herbicides for the control of volunteer soybean in the castor crop. Two greenhouse experiments were carried out in a completely randomized design with four replications. The first assay was focused on the selectivity of herbicides to the castor crop, and the second to the efficacy of herbicides for soybean con trol. Evaluation of herbicide selectivity for the castor cultivar BRS Energia was carried out at 4 to 6 true leave stages. The treatments corresponded to two doses of ethoxysulfuron, halosulfuron-methyl, iodosulfuron-methyl, ioxynil, metamitron, oxadiazon and a control without any application. To evaluate the control efficacy of soybean cultivar BRS 3280RR in 3 trefoil stage, the treatments were comprised of two doses of ethoxysulfuron, halosulfuron-methyl, metamitron and a control without application. The evaluations were: control, phytointoxication and plant height at 7, 14 and 21 DAA; stem diameter, leaf area, dry mass of aerial part and roots at 21 DAA. The results showed that herbicides ethoxysulfuron (60 and 80 g ha ) and halosulfuron-methyl (75 and 112.5 g ha -1) were effective for the volunteer soybean control.
