“…However, injury from flumioxazin was transient and was not observed by 56 DAT at either application rates. Richard and Dalley (2006) reported no visible injury on sugarcane 6 wk after treatment from PRE application of flumioxazin at 0.28 and 0.42 kg ha À1 . Injury to energycane at 56 DAT increased to 71 and 98% with treatments containing hexazinone and clomazone, respectively.…”

“…Energycane injury from flumioxazin was 21 to 38% and included reddening and necrosis following POST application at both rates. Richard and Dalley (2006) reported injury on sugarcane of up to 40% from POST application of flumioxazin at 0.28 kg ha À1 . In sugarcane, injury from flumioxazin can be minimized by using POST-directed sprays rather than over-the-top applications (Richard and Dalley 2006).…”

In sugarcane, injury from flumioxazin can be minimized by using POST-directed sprays rather than over-the-top applications (Richard and Dalley 2006). These results show that clomazone, diuron, and flumioxazin cannot be used as over-the-top or POSTdirected herbicides in energycane for weed control because of risk of severe injury.…”

“…There are several herbicides, including 2,4-D amine, asulam, atrazine, carfentrazone, clomazone, dicamba, diuron, flumioxazin, halosulfuron, hexazinone, mesotrione, metribuzin, pendimethalin, Smetolachlor, and trifloxysulfuron, currently used in conventional sugarcane (Bhullar et al 2012;Correia et al 2012;Dalley and Richard 2008;Judice et al 2006;Richard and Dalley 2006), which can potentially be used in energycane if there is acceptable crop tolerance. Because differential tolerance and sensitivity of other crops, such as corn (Zea mays L.), to herbicides have been reported (Diebold et al 2004;Green 1998;Grey et al 2000;O'Sullivan and Sikkema 2002;Widstrom and Dowler 1995;Williams et al 2005), energycane tolerance to sugarcane herbicides needs to be evaluated to provide potential growers with options for selective weed control if planted hectares increase in the future in the southeast United States.…”

Response of Energycane to Preemergence and Postemergence Herbicides

et al. 2015

Energycane has been proposed as a potential, perennial bioenergy crop for lignocellulosic-derived fuel production in the United States. Herbicides currently used in sugarcane and other crops can potentially be used in energycane if there is acceptable tolerance. Also, to limit future invasion of energycane escapes, herbicides used for perennial grass control could potentially be used for management of escapes. In container studies conducted outside, aboveground and belowground biomass of energycane was measured to evaluate energycane tolerance to 9 PRE and 19 POST herbicides used in sugarcane and other crops. PRE application of atrazine, diuron, mesotrione, metribuzin, pendimethalin, andS-metolachlor at rates labeled for sugarcane did not significantly injure (< 3%) or reduce energycane biomass compared with the nontreated plants 28 and 56 d after treatment (DAT). Injury from clomazone (54%), flumioxazin (7%), and hexazinone (29%) was observed 28 DAT. Injury from flumioxazin was transient and was not observed at 56 DAT. At 56 DAT, energycane injury increased to 71 and 98%, respectively, for clomazone and hexazinone. Hexazinone and clomazone applied PRE significantly reduced biomass compared with the nontreated plants. At 28 DAT, POST application of 2,4-D amine, ametryn, asulam, atrazine, carfentrazone, dicamba, halosulfuron, mesotrione, metribuzin, and trifloxysulfuron at labeled rates for sugarcane did not injure or significantly reduce energycane biomass compared with the nontreated plants. Injury was observed when clethodim (99%), clomazone (51%), diuron (51%), flumioxazin (21%), glufosinate (84%), glyphosate (100%), hexazinone (100%), paraquat (66%), and sethoxydim (100%) were applied POST, and each of these treatments reduced energycane biomass compared with the nontreated plants. These results show that several PRE and POST herbicides used for weed management in sugarcane may potentially be used in energycane for weed control. Also, based on our results, clethodim, glyphosate, and sethoxydim would be effective for management of energycane escapes.

“…(4.5 and 2.1 plants m 22 , respectively). Herbicides applied PRE are effective for controlling grass and broadleaf weeds in sugarcane, but in most cases they do not provide long-term weed control and additional weed control treatments are required (Griffin and Judice 2009;Richard and Dalley 2006). The application of atrazine has been a common practice for many years among sugarcane producers in the Punjab province.…”

Control of Morningglories (Ipomoeaspp.) in Sugarcane (Saccharumspp.)

et al. 2012

Morningglories are summer annual or perennial dicots, and are troublesome weeds in sugarcane cultivated in northern India. If not controlled, they may compete with sugarcane, interfere in the harvest operation, and reduce yields. Managing morningglories in sugarcane continues to be a serious challenge for sugarcane growers. Field experiments were conducted during the 3-yr period from 2007 to 2009 to evaluate herbicides applied PRE and POST for control of morningglories in sugarcane. The herbicides applied PRE included diuron, metribuzin, and atrazine at 1.6, 1.4, and 1.0 kg ai ha−1, respectively, applied alone or followed by 2,4-D amine salt (0.58 or 1.16 kg ae ha−1) or 2,4-D sodium salt (0.8 or 1.6 kg ae ha−1) applied POST. Herbicides applied PRE controlled morningglories ≤ 87% at 15 d after treatment (DAT); however, control reduced to ≤ 56% at 90 DAT. Control improved when herbicides applied PRE were followed by POST application of 2,4-D amine or sodium salt. For example, diuron applied PRE followed by 2,4-D amine salt applied POST at any rate provided 100% control of morningglories at 15 and 30 DAT. At 90 d after POST application, control ranged from 68 to 82% with the PRE followed by POST herbicides, compared to 0% control when metribuzin or atrazine were applied PRE alone. The density and biomass of morningglories was also reduced to zero in treatments that included 2,4-D amine salt. The number of millable canes, cane height, and single cane weight was superior in PRE followed by POST herbicide treatments compared to herbicides applied PRE alone. Maximum cane yield was recorded for the treatments that included 2,4-D amine or sodium salt compared to only PRE treatments, and it was usually comparable with the nontreated weed-free control. It is concluded that a combination of PRE and POST herbicides were effective for control of morningglories; however, more research is required to evaluate other herbicides and their tank mix partners for control of morningglories in sugarcane.

Herbicide mixtures are a modern weed management practice as they reduce herbicide application. This study aimes to evaluate the effect of metribuzin, halosulfuron and flumioxazin applied individually and as mixtures (metribuzin:halosulfuron and metribuzin:flumioxazin) on Chenopodium album, Amaranthus retroflexus, and potatoes on biomass and chlorophyll-a fluorescence in 21 experiments. The individual herbicide experimental design was a randomized completely block design with seven doses and three replications. The factorial experiments were performed on the basis of randomized completely block design in three replications for binary mixture experiments. Flumioxazin was very potent in controlling C. album, A. retroflexus, and injured potatoes with a 50% effective dose (ED50) of 1.21, 0.54, and 12.23 g ai·ha−1, respectively. Both mixtures of metribuzin:halosulfuron and metribuzin:flumioxazin generally showed an antagonistic effect on both weeds and potato in 12 independent experiments. Metribuzin, halosulfuron, and flumioxazin significantly decreased photosystem II activity by decreasing the maximum quantum efficiency (Fv/Fm). The metribuzin:halosulfuron mixtures almost followed the Additive Dose Model for Fv/Fm, whilst there was an antagonistic effect for the metribuzin:flumioxazin that was closely related to biomass. The results indicated that mixtures were generally antagonistic, and the endpoint choice is pivotal when assessing the joint action of mixtures.
