“…They concluded if given ample time to compensate for delays in maturity, peanut yield should not be affected. Similar results were also reported by Jordan et al (2009) in which they found that delaying the application of flumioxazin until peanut emergence increased injury regardless of rate but pod yield was not affected.…”

“…), prickly sida (Sida spinosa L.), and Florida beggarweed (Desmodium tortuosum (Sw.) DC) (Wilcut, 1997) while in Texas, pitted morningglory [Ipomoea lacunosa L.] were controlled greater than 75% (Grichar and Colburn, 1996). Flumioxazin has been reported to cause peanut injury especially when the application is delayed until peanut emergence (Johnson et al, 2006;Jordan et al, 2009;Tredaway-Ducar et al, 2009). When applied soon after peanut planting (1 to 2 d), Grichar et al (2004) reported that flumioxazin plus metolachlor combinations, under cool, wet conditions resulted in peanut stunting which was evident throughout the growing season.…”

Field studies were conducted in the Texas High Plains and south Texas to determine peanut response to flumioxazin and paraquat applied preemergence or 7 days after ground cracking (DAC). These herbicides were applied either alone or in combination. Smellmelon control was greater than 90% with all 7 DAC treatments while preemergence (PRE) treatments of flumioxazin plus paraquat controlled 87 to 97% in one of two years. No peanut injury was noted following either herbicide applied preemergence; however, earlyseason injury (stunting and leaf chlorosis/necrosis) was evident with flumioxazin and paraquat alone or in combination when applied 7 DAC. Earlyseason injury in south Texas from the 7 DAC applications of flumioxazin and paraquat varied from 9 to 63% with flumioxazin alone, 18 to 65% with paraquat alone, and 33 to 83% with combinations of the two herbicides. Injury in the Texas High Plains was never more than 40% with either herbicide alone or in combination. Midseason injury in south Texas was at least 13% with any combination that included flumioxazin at 0.11 kg/ha while injury in the Texas High Plains varied from 12 to 25%. Peanut yields were not affected by flumioxazin and paraquat in the High Plains area although yields in south Texas were reduced from the untreated weed-free check with combinations of flumioxazin and paraquat.

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

2015

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.

“…Bukun (2011) aggregated that the number of red root pigweed (Amaranthus retroflexus) for 5 plants/m 2 showed the maximum of the yield loss percentages against peanut (Arachis hypogoea) for 70%, while the number of red root pigweed (A. retroflexus) for 1 plants/m 2 exhibited the minimum of the yield loss percentages against peanut (A. hypogoea) for 25%. Jordan et al (2009) comprehended that the peanut (A.…”

The aim of this study was to evaluate of the density for four weeds on growth inhibition against soybean (Glycine max) (Chiang Mai 2 variety). The experiment were interfered with four weeds namely wild poinsettia (Euphorbia heterophylla), eclipta (Eclipta prostrata), slender amaranth (Amaranthus viridis) and spiny amaranth (Amaranthus spinosus) against soybean (G. max). The number of four weeds interfered with soybean planting divided into five treatments; 0 (control treatment) 4 8 12 and 16 plants/m 2 . Stem height, leaf area, fresh weight of aboveground part and dry weight of aboveground part of soybean were measured at 28 days after planting. The results showed that the increase of number of four weeds resulted in the increase of inhibition of all growth performance in soybean. The planting of soybean interfered with the weeds for 16 plants/m 2 exhibited that the maximum of inhibitory degree (52.61%) followed by the planting of soybean interfered with the weeds for 12 8 and 4 plants/m 2 by 40.04, 25.94 and 13.08%, respectively. The planting of soybean interfered with spiny amaranth (A. spinosus) exhibited that the highest of inhibitory degree (35.41%), followed by the planting of soybean interfered with eclipta (E. prostrata), wild poinsettia (E. heterophylla) and slender amaranth (A. viridis) showed the inhibitory degree for 34.35, 31.65 and 30.27%, respectively. This result presented the effects of density of weeds against soybean on growth parameters (stem height, leaf area, fresh weight of aboveground part and dry weight of aboveground part) as well as suggested that the planting of soybean should be the planting of soybean were not interfered with different weed density in order to the minimization of weed competition as well as the optimum method for weed arrangement.
