“…Halosulfuron applied PRE and POST at 35 to 106 g ai/ha controls yellow nutsedge, reducing regrowth and tuber production (Ackley et al 1996;Blum et al 2000;Earl et al 2004;Ferrell et al 2004;Nelson and Renner 2002;Vencill et al 1995). Halosulfuron applied PRE or POST at 10 to 106 g/ha controls purple nutsedge, reducing regrowth and tuber production (Blum et al 2000;Grichar et al 2003;Molin et al 1999;Rao and Reddy 1999;Vencill et al 1995).…”

Studies were conducted in 2003 and 2004 to determine the effect of application timing and halosulfuron rate on sweetpotato yield and quality. Halosulfuron was applied 1, 2, and 4 wks after transplanting (WAP) sweetpotato in 2003, and 2, 3, and 4 WAP in 2004. Treatments within each timing included halosulfuron at 13, 26, 39, 52, and 65 g ai/ha plus a weed-free control. Combined over year, site, cultivar and rate, halosulfuron applied at 1, 2, 3, and 4 WAP stunted sweetpotato 32, 15, 11, and 14%, respectively, rated 2 wks after treatment. The stunting observed with the 1 and 2 WAP timings caused a 17 and 10% reduction in yield of No. 1 roots, respectively, compared with the weed-free control. The 3 and 4 WAP timings of halosulfuron did not reduce yield of No. 1 roots. Total yield was reduced approximately 11% at the 1, 2, and 3 WAP application timings. Halosulfuron at 4 WAP did not reduce total yield. Combined over year, site, and cultivar, halosulfuron applied at 39 g/ha did not reduce the weight of No. 1 roots or total crop yield and thus could be an effective POST option for weed control in sweetpotato.

“…Halosulfuron (Sandea; Gowan Company, Yuma, Ariz.) has been identified as a potential herbicide for use in several cucurbit crops (Batts et al, 2001;Brown and Masiunas, 2002;Haar et al, 2002;Johnson and Mullinix, 2002). Halosulfuron, applied in a number of crops controlled yellow and purple nutsedge (Blum et al, 2000;Derr et al, 1996;Vencill et al, 1995), impeded tuber production (Lowe et al, 2000;Nelson and Renner, 2002;Warren and Coble, 1999), and reduced tuber viability (Molin et al, 1999). Previous studies with cucurbits indicated that certain species and cultivars within a species had greater sensitivities than others (Buker and Stall, 2001;Stall and Majek, 1995;Webster et al, 2003), and application method affected crop injury (Garvey et al, 1997;Mitchem and Monks, 1997).…”

Halosulfuron Has a Variable Effect on Cucurbit Growth and Yield

Halosulfuron is a proposed alternative to methyl bromide for managing nutsedges (Cyperus spp.) in several vegetable crops, including cucurbits. Field studies were conducted to evaluate the crop sensitivity to halosulfuron in a spring squash (Cucurbita pepo L.)—fall cucumber (Cucumis sativus L.) rotation from 2000 to 2002. Treatments included application of halosulfuron to the soil surface after forming the bed, but before laying mulch (halosulfuron-PRE), halosulfuron applied through drip irrigation (halosulfuron-DRIP) after forming bed and laying mulch, metham applied through drip irrigation after forming bed and laying mulch, a nontreated control with mulch, and nontreated control without mulch. Each treatment was applied to both direct seeded and transplanted zucchini squash. Halosulfuron treatments reduced squash plant diameter relative to metham, however plant diameters in halosulfuron-PRE (transplant and direct seed) and halosulfuron-DRIP (transplant) treatments were not different from the nontreated control. Halosulfuron-PRE delayed squash fruit production relative to the mulched nontreated control. However, application of halosulfuron-PRE and halosulfuron-DRIP did not reduce squash yield at the conclusion of the season, relative to the nontreated control. Cucumbers were transplanted and direct seeded into previous squash plots and received either an application of halosulfuron-DRIP, or were not treated. Differences in cucumber yields were not detected with second crop treatments. Cucumbers appear to have adequate tolerance to halosulfuron, making it a potential replacement for methyl bromide for nutsedge control. Suppression of early season squash growth by halosulfuron may hinder the adoption of halosulfuron as a methyl bromide alternative for squash.

Halosulfuron controls purple and yellow nutsedge (Blum et al, 2000;Derr et al, 1996;Vencill et al, 1995), impedes tuber production (Lowe et al, 2000;Nelson and Renner, 2002;Warren and Coble, 1999), reduces tuber viability (Molin et al, 1999), prevents shoot regrowth and reduces nutsedge competitiveness . While halosulfuron effectively controls both nutsedge species, crop tolerance limits adoption of this tactic for a broad range of vegetable crops.…”

Halosulfuron is an alternative to methyl bromide for managing nutsedges (Cyperus spp.) in several vegetable crops. Field studies were conducted to evaluate eggplant growth and yield when halosulfuron was applied through drip-irrigation before transplant at four rates (0, 26, 39, or 52 g·ha–1 a.i.) or following transplant (26 g·ha–1 applied 1, 2, or 3 weeks after transplant) in spring and fall crops in 2002 and 2003. Inverse linear relationships were observed between rate of halosulfuron and eggplant growth and rate of halosulfuron and eggplant yield. Halosulfuron at 52 g·ha–1 reduced eggplant growth (crop height and canopy width) 19% to 22%. Eggplant fruit biomass at the first harvest was reduced 37% to 63% by halosulfuron applied before transplant. Eggplant was capable of recovering from the initial injury and there was no effect of halosulfuron rate on fruit biomass at the final harvest. Total season fruit biomass was reduced ≤4% from halosulfuron at 39 g·ha–1, while halosulfuron at 52 g·ha–1 reduced fruit biomass 33%. Delay in application of halosulfuron to 3 weeks after transplant (WAT) resulted in ≤7% reduction in fruit biomass and number for the entire season. When halosulfuron was applied 1 WAT, fruit biomass at the first two harvests was reduced >33%, however total season harvest from this treatment was >99% of the yield from the nontreated control. This preliminary study indicates that halosulfuron injected through drip tape may have the potential to assist in the replacement of methyl bromide for nutsedge management in eggplant. However, there are many issues that must be addressed and studied before adopting this practice in eggplant.
