“…At the Starkville location, flumioxazin was applied at the cracking stage instead of preemergence and little injury was observed, but pod yield was still lower than where flumioxazin was not used. Previous research suggests that flumioxazin rarely causes yield losses in peanut when applied preemerge (Scott et al 2001, Grichar et al 2004, Grichar and Dotray 2013. Additionally, temporary flooding within two d after seedling emergence reduced yields of peanut at the Stoneville location, further supporting the impact of early season stress impacting pod yield.…”

Experiments were conducted in 2016 and 2017 in Stoneville, MS and Starkville, MS to determine the impact of different insecticide management options for thrips on herbicide injured peanut. Insecticide treatments included imidacloprid in-furrow at-planting, one or two foliar applications of acephate, and an untreated control with and without an application of flumioxazin. In Stoneville, herbicide applications were made immediately following planting, and in Starkville, applications were made as plants were emerging to maximize herbicide injury. The Stoneville experiment also had an additional factor in which plots were flooded or not flooded to simulate a heavy rainfall in order to maximize herbicide injury and also to give added stress from saturated soils. Thrips counts, thrips injury ratings, plant vigor ratings, plant biomass, width between plant canopies, and yield were recorded. Few interactions were observed, but temporary flooding, herbicide injury, and thrips injury affected peanut growth as measured by biomass and canopy. Imidacloprid was the most consistent insecticide treatment for reducing thrips numbers and injury, but acephate provided some protection. Temporary flooding during the seedling stage, flumioxazin injury, and thrips injury all reduced peanut pod yield. Based on these results, every attempt should be made to minimize early season stress in peanuts including the use of an effective in-furrow insecticide.

“…In 2012, smellmelon control with acetochlor, flumioxazin, pendimethalin, or S-metolachlor alone ranged from 67 to 75% while all pendimethalin combinations provided 86 to 99% control. Grichar and Dotray (2013) reported inconsistent control of smellmelon with flumioxazin. In one year, flumioxazin at either 0.07 or 0.11 kg/ha controlled less than 55% while in another year smellmelon control was 77 and 96%, respectively.…”

Weed Control and Peanut (Arachis hypogaea L.) Cultivar Response to Encapsulated Acetochlor

Field studies were conducted during 2011 and 2012 in the Texas peanut production regions to evaluate encapsulated acetochlor for weed control and cultivar response. Acetochlor alone applied preemergence (PRE) controlled horse purslane, Palmer amaranth, smellmelon, and Texas millet as well as flumioxazin or S-metolachlor. The addition of pendimethalin to either acetochlor, flumioxazin, or S-metolachlor did improve weed control in some instances. In another study comparing the three above mentioned herbicides alone or followed by lactofen postemergence (POST), the addition of lactofen to acetochlor, flumioxazin, or S-metolachlor improved control of smellmelon and Palmer amaranth in some instances but did not affect horse purslane control. In a tolerance study to evaluate potential differences in variety response to acetochlor at 1.26 (1X) and 2.52 kg ai/ha (2X) applied preplant incorporated (PPI), PRE, early postemergence (EPOST), or POST, peanut yield or grade was not affected by either rate of acetochlor or application timing.

Flumioxazin does not effectively control C. esculentus (Ducar et al 2009; Grey et al 2004), S. obtusifolia (Grey and Wehtje 2005; Johnson et al 2010; Willingham et al 2008), and wild poinsettia ( Euphorbia heterophylla L.)

Herbicides are the primary tool for controlling weeds in peanut and are crucial to sustainable peanut (Arachis hypogaea L.) production in the United States (US). The literature on chemical weed management in peanut in the past 53 years (1970 to 2022) in the US was systematically reviewed to highlight the strength and weaknesses of different herbicides and identify current research gaps in chemical weed management. Residual weed control in peanut is achieved mainly with dimethenamid-P, ethalfluralin, flumioxazin, pendimethalin, and S-metolachlor. More recently, the use of the PPO-inhibitor, and ALS-inhibitors such as diclosulam for residual weed control in peanut has increased considerably. Postemergence broadleaf weed control in peanut is achieved mainly with acifluorfen, bentazon, diclosulam, imazapic, lactofen, paraquat, and 2,4−DB, while the graminicides clethodim and sethoxydim are the major postemergence grass weed control herbicides in peanut. Although several herbicides are available for weed control in peanut, no single herbicide can provide season-long weed control due to limited application timing, lack of extended residual activity, variability in weed control spectrum, and rotational restrictions. Therefore, effective weed management in peanut often requires herbicide mixtures and/or sequential application of pre-plant incorporated, preemergence, and/or postemergence herbicides. However, the available literature showed a substantive range in herbicide efficacy due to variations in environmental conditions and flushes of weed germination across years and locations. Despite the relatively high efficacy of herbicides, the selection of herbicide-resistant weeds is another area of increasing concern. Future research should focus on developing new strategies for preventing or delaying the development of resistance and improving herbicide efficacy within the context of climate change and emerging constraints such as water shortages, temperature rise and increasing CO2 concentration.
