“…Quizalofop inhibits acetyl coenzyme A carboxylase (ACCase), with postemergence activity on annual and perennial grass species [13,14]. Producers can use ACCaseresistant rice (ACCase-R) to manage weedy rice and other grass species during cultivated rice production [15]. Rotation of herbicides and herbicide mixtures with differing sites of action is important for sustainable rice production.…”

“…In order to increase weed control, herbicide mixtures have proven to be beneficial by increasing weed control spectrum, increasing the yield and economic returns [16][17][18][19][20]. Herbicide mixtures may exhibit three responses: synergistic, antagonistic, or neutral [15,[21][22][23][24][25][26][27][28]. A neutral response occurs when the observed control is equivalent to the expected control calculated using Colby's response [15,21,23,24,27,28].…”

A study was conducted near Crowley, Louisiana, to evaluate the efficacy of quizalofop-p-ethyl mixed with different synthetic auxin and ACCase-inhibiting herbicides for barnyardgrass and weedy rice control in rice production systems. Quizalofop was applied at 0 or 120 g ai·ha−1 mixed with 2,4-D at 1336 g ai·ha−1, triclopyr at 282 g ai·ha−1, quinclorac at 420 g ai·ha−1, cyhalofop-butyl at 314 g ai·ha−1, or fenoxaprop-p-ethyl at 122 g ai·ha−1. Cyhalofop, fenoxaprop, 2,4-D, quinclorac, and triclopyr antagonized quizalofop for barnyardgrass control at 14 days after treatment (DAT). At 28 DAT, an antagonistic response persisted for barnyardgrass control, except when cyhalofop was mixed with quizalofop, which indicated a neutral response. Red rice, CLXL-745, and CL-111 control decreased due to antagonism of quizalofop when mixed with 2,4-D. However, quinclorac, triclopyr, cyhalofop, or fenoxaprop mixed with quizalofop resulted in a neutral response for red rice, CLXL-745, and CL-111 control at 28 DAT.

Evaluation of weed control in acetyl coA carboxylase-resistant rice with mixtures of quizalofop and auxinic herbicides

et al. 2019

Rice with enhanced tolerance to herbicides that inhibit acetyl coA carboxylase (ACCase) allows POST application of quizalofop, an ACCase-inhibiting herbicide. Two concurrent field studies were conducted in 2017 and 2018 near Stoneville, MS, to evaluate control of grass (Grass Study) and broadleaf (Broadleaf Study) weeds with sequential applications of quizalofop alone and in mixtures with auxinic herbicides applied in the first or second application. Sequential treatments of quizalofop were applied at 119 g ai ha−1 alone and in mixtures with labeled rates of auxinic herbicides to rice at the two- to three-leaf (EPOST) or four-leaf to one-tiller (LPOST) growth stages. In the Grass Study, no differences in rice injury or control of volunteer rice (‘CL151’ and ‘Rex’) were detected 14 and 28 d after last application (DA-LPOST). Barnyardgrass control at 14 and 28 DA-LPOST with quizalofop applied alone or with auxinic herbicides EPOST was ≥93% for all auxinic herbicide treatments except penoxsulam plus triclopyr. Barnyardgrass control was ≥96% with quizalofop applied alone and with auxinic herbicides LPOST. In the Broadleaf Study, quizalofop plus florpyrauxifen-benzyl controlled more Palmer amaranth 14 DA-LPOST than other mixtures with auxinic herbicides, and control with this treatment was greater EPOST compared with LPOST. Hemp sesbania control 14 DA-LPOST was ≤90% with quizalofop plus quinclorac LPOST, orthosulfamuron plus quinclorac LPOST, and triclopyr EPOST or LPOST. All mixtures except quinclorac and orthosulfamuron plus quinclorac LPOST controlled ivyleaf morningglory ≥91% 14 DA-LPOST. Florpyrauxifen-benzyl or triclopyr were required for volunteer soybean control >63% 14 DA-LPOST. To optimize barnyardgrass control and rice yield, penoxsulam plus triclopyr and orthosulfamuron plus quinclorac should not be mixed with quizalofop. Quizalofop mixtures with auxinic herbicides are safe and effective for controlling barnyardgrass, volunteer rice, and broadleaf weeds in ACCase-resistant rice, and the choice of herbicide mixture could be adjusted based on weed spectrum in the treated field.

“…Quizalofop has historically been used for weedy rice management in soybean production at rates from 35 to 84 g ai ha −1 (Askew et al 1998;Minton et al 1989). The targeted quizalofop application rate in ACCase-R production is 92 to 155 g ai ha −1 , not to exceed 240 g ha −1 per year (Rustom et al 2018(Rustom et al , 2019.…”

“…Herbicide antagonism is defined as "an interaction of two or more chemicals such that the effect when combined is less than the predicted effect based on each chemical applied separately" (Beste 1983:515). ACCase-inhibiting herbicide activity has a history of antagonism when co-applied with other herbicides (Barnwell and Cobb 1994;Blackshaw et al 2006;Osterholt et al 2019;Rustom et al 2018Rustom et al , 2019Vidrine et al 1995;Webster et al 2019;Zhang et al 2005). Rustom et al (2018) reported antagonism of quizalofop for weedy rice and barnyardgrass control in ACCase-R rice production when treated with mixtures of quizalofop plus acetolactate synthase-inhibiting herbicides such as halosulfuron, orthosulfamuron, imazosulfuron, bensulfuron, penoxsulam, or bispyribac-sodium.…”

A field study was conducted in 2015 and 2016 at the H. Rouse Caffey Rice Research Station near Crowley, Louisiana, to evaluate the interactions of quizalofop and a mixture of propanil plus thiobencarb applied sequentially or mixed to control weedy rice and barnyardgrass. Visual weed control evaluations occurred at 14, 28, and 42 d after treatment (DAT). Quizalofop was applied at 120 g ai ha−1 at 7, 3, and 1 d before and after propanil plus thiobencarb were each applied at 3,360 g ai ha−1. In addition, quizalofop was applied alone and in a mixture with propanil plus thiobencarb at day 0. Control of red rice ‘CL-111’ and ‘CLXL-745’ was greater than 91% when quizalofop was applied alone at day 0, similar to control for quizalofop applied 7, 3, and 1 d prior to propanil plus thiobencarb at all evaluation dates. Control of the same weeds treated with quizalofop plus propanil plus thiobencarb applied in a mixture at day 0 was 70% to 76% at each evaluation date, similar to quizalofop applied 1 or 3 d after propanil plus thiobencarb. A similar trend in control of barnyardgrass by 88% to 97% occurred when quizalofop was applied alone and by 48% to 53% at 14, 28, and 42 DAT when the mixture was used. ‘PVL01’ rough rice yield was 4,060 kg ha−1 when treated with quizalofop alone; however, yield was reduced to 3,180 kg ha−1 when it was treated with quizalofop mixed with propanil plus thiobencarb at day 0, similar to PVL01 rice treated with quizalofop 1 or 3 d following the propanil plus thiobencarb application.
