Un mejor conocimiento del manejo de las especies nativas de leguminosas forrajeras como Adesmia bicolor puede ayudar a lograr una mayor calidad y estabilidad en la producción de los pastizales. No existe información disponible en la Argentina sobre el tipo y dosis de herbicidas adecuados para el control de malezas en A. bicolor. Los objetivos fueron evaluar el efecto fitotóxico de herbicidas postemergentes a diferentes dosis sobre A. bicolor y el control de las malezas latifoliadas que crecen asociadas en ensayos a campo durante 2009 y 2010. El diseño fue de parcelas divididas donde la parcela mayor fue el tipo de herbicida (2,4-DB e imazetapir) y la parcela menor la dosis (1/4X, 1/2X, 1X, 2X, 4X, 8X, siendo X = 250 g i.a. ha-1 para 2,4-DB y X=100 g i.a. ha-1 para imazetapir), con tres repeticiones para cada tratamiento. La materia seca de A. bicolor y el control de malezas se ajustaron a curvas de dosis-respuesta. Se observó efectos fitotóxicos aun con muy baja dosis de 2,4-DB, mientras que imazetapir mostró baja fitotoxicidad para las dosis entre 25 y 100 g a.i. ha-1. El control de malezas con ambos herbicidas fue mayor al 80% con dosis de 1X.

Sensitivity and Recovery of Grain Sorghum to Simulated Drift Rates of Glyphosate, Glufosinate, and Paraquat

et al. 2019

A field experiment was conducted in 2017 and 2018 to evaluate the sensitivity and recovery of grain sorghum to the simulated drift of glufosinate, glyphosate, and paraquat at two application timings (V6 and flag leaf growth stage). Paraquat drift caused maximum injury to sorghum plants in both years, whereas the lowest injury was caused by glyphosate in 2017. Averaged over all herbicide treatments, injury to grain sorghum from the simulated herbicide drift was 5% greater when herbicides were applied at flag leaf stage, as compared to herbicide applications at the six-leaf stage in 2017. In 2018, injury from glyphosate drift was higher when applied at the six-leaf stage than at the flag leaf stage. Paraquat and glufosinate drift caused more injury when applied at flag leaf stage than at six-leaf stage at 14 days after application in 2018. About 21% to 29% of injury from the simulated drift of paraquat led to a 31% reduction in grain sorghum yield, as compared to a nontreated check in 2017. The simulated drift of glyphosate and glufosinate did not result in any significant yield reduction compared to the nontreated check in 2017, possibly due to the recovery of sorghum plants after herbicides’ drift application.

“…Recently, several farmers in the southern US have observed halosulfuron injury in soybean through off-target movement of halosulfuron when applied to rice fields (Whiting, personal observation). Off-target movement of herbicides during application can range from 0.01 to 10% of the applied rate [6,7]. Although these drift rates appear to be sublethal, the injury can be severe in susceptible crops, depending on the growth stage.…”

Recently, halosulfuron injury in soybean through off-target movement of halosulfuron when applied to rice fields has been reported. Sulfonylurea-tolerant (ST) soybean varieties have enhanced tolerance for sulfonylurea herbicides and might provide an option for mitigating injury to soybean from halosulfuron drift. Experiments were conducted to evaluate the effect of halosulfuron on growth and yield of selected soybean varieties with ST trait alone and stacked with glyphosate resistance trait. Soybean plants were treated with halosulfuron at 0, 0.0043, 0.0087, 0.017, 0.034, and 0.069 kg ai/ha rate at the V3 growth stage in the greenhouse and at 0.034 kg/ha rate (labeled use rate in rice) in the field studies. All soybean varieties containing the ST trait exhibited some halosulfuron injury, but survived the halosulfuron application in the greenhouse. In field studies, a single POST application of halosulfuron at 0.034 kg/ha to soybean at three-trifoliolate leaf stage or at full bloom stage resulted in halosulfuron injury to a certain extent regardless of ST trait. Halosulfuron did not have a significant effect on yield of ST varieties compared to their respective nontreated controls. Severe halosulfuron injury in two non-ST varieties resulted in yield loss.
