Halosulfuron is labeled for use under plastic for freshmarket tomato (Lycopersicon esculentum Mill.), and has significantly improved management of yellow nutsedge. Halosulfuron is not labeled for control of grasses. There is a need to determine how halosulfuron weed control can be improved and determine its application timing flexibility. Experiments were conducted at two locations to evaluate halosulfuron, applied alone or in tank-mixes with trifluralin or oxyfluorfen, at intervals shorter than label recommendations, and to determine efficacy and crop safety in plasticulture fresh-market tomato in Kentucky, USA and in Uruguay. Halosulfuron, trifluralin, and oxyfluorfen were equally safe to plants when applied at 0 or 7 days before transplanting tomato. Yields at both locations indicated that addition of trifluralin or oxyfluorfen to halosulfuron had no negative effect on tomato plant size and total yields. Yields were less with halosulfuron applied alone than in tank mixes with trifluralin or oxyfluorfen. Trifluralin and oxyfluorfen are potential tank mix partners with halosulfuron for use under plastic mulch. It appears that halosulfuron alone or in tank mixes is safe for application at intervals shorter than current label recommendations.

“…Florida strawberry growers have increasingly reported that black medic ( Medicago lupulina L.), cutleaf evening primrose ( Oenothera laciniata Hill), Carolina geranium, and Florida pusley ( Richardia scabra L.) are problematic and difficult to control (Boyd and Reed 2016). Moreover, purple ( Cyperus rotundus L.) and yellow ( Cyperus esculentus L.) nutsedges not only emerge from the planting hole but also pierce the polyethylene mulch (Adcock et al 2008; Johnson and Mullinix 2008; Monday et al 2015; Webster 2005). A 2010 survey by the Southern Weed Science Society reported that purple and yellow nutsedges are the most common and troublesome weeds in fruiting vegetable crops in Florida (Webster 2010).…”

Weed Control with and Strawberry Tolerance to Herbicides Applied through Drip Irrigation

Broadleaves, grasses, and nutsedge species are persistent problems with limited management options for strawberry growers in Florida. Field experiments were conducted in 2015-2016 (year 1) and 2016-2017 (year 2) at the Gulf Coast Research and Education Center in Balm, FL, to evaluate weed control and strawberry tolerance to herbicides applied through the drip irrigation. 2940 g ai ha , and 1070 g ai ha -1 S-metolachlor were applied through a single drip tape at 7 or 14 d prior to transplanting. Halosulfuron was the most injurious herbicide, causing 18 and 46% injury at 35 d after transplanting (DATP) in year 1 when the herbicide was applied 7 and 14 d prior to transplanting, respectively. However, strawberry plants recovered from the initial injury and there was no reduction in total berry yield. None of the other herbicides evaluated elicited significant crop injury nor reduced berry yield. Averaged over application timings, EPTC, fomesafen, and napropamide suppressed yellow nutsedge emergence to 49, 64, and 41% of the nontreated control, respectively. Flumioxazin, fomesafen, and halosulfuron suppressed black medic emergence to 55, 52, and 55% of the nontreated control, respectively. None of the herbicides evaluated adequately suppressed Carolina geranium. Overall, results suggest that the evaluated herbicides with the exception of halosulfuron are safe for use on strawberry and would give growers an alternative management option. Drip-applied herbicides permit application closer to the transplant date and would be helpful as part of a weed control program for weed suppression. Nomenclature: EPTC; flumioxazin; fomesafen; halosulfuron; napropamide; oxyfluorfen; S-metolachlor; Carolina geranium, Geranium carolinianum L.; purple nutsedge, Cyperus rotundus L.; strawberry, Fragaria × ananessa (Weston) Duchesne ex Rozier.

Eggplant (Solanum melongena L.) height, fruit number, and fruit yield followed an inverse linear relationship to halosulfuron rate (0, 26, 39, and 52 g ai ha 21 ) applied pretransplant through the drip irrigation (Webster and Culpepper 2005). Total fruit yield from halosulfuron at 26 g ai ha 21 applied 1, 2, and 3 wk after transplant was similar to the nontreated check (Webster and Culpepper 2005).…”

Effect of Drip-Applied Herbicides on Yellow Nutsedge (Cyperus esculentus) in Plasticulture

Greenhouse and field studies were conducted to determine the effect of halosulfuron, imazosulfuron, and trifloxysulfuron applied through drip irrigation on yellow nutsedge. In greenhouse studies, yellow nutsedge control by halosulfuron, imazosulfuron, and trifloxysulfuron was greater (69 to 91%) than the nontreated control (0%). Yellow nutsedge treated with halosulfuron POST had a lower photosynthetic rate (0.6 to 22.6 µmol m−2 s−1) at 4, 7, and 14 d after treatment than the nontreated control (3.3 to 26.2 µmol m−2 s−1). Yellow nutsedge treated with trifloxysulfuron had lower photosynthetic rate and stomatal conductance than the nontreated plants. In field studies at Clinton, NC, yellow nutsedge density increased from treatment (day 0) to 56 d after treatment in all treatments. Increase in yellow nutsedge density was 72 and 95% in drip-applied halosulfuron and imazosulfuron treatments compared with yellow nutsedge density increases of 876% for the same period in the nontreated plots. Yellow nutsedge density increased 69 and 57% at Clinton and Kinston, NC, respectively, in the drip-applied 15 g ha−1 trifloxysulfuron treatment compared with 876% in the nontreated control. In field studies at Clinton and Kinston, NC, suppression of yellow nutsedge emergence in POST and drip-applied herbicide treatments was similar. Emergence of yellow nutsedge was similar in the imazosulfuron POST and the nontreated yellow nutsedge. Based on these studies, drip-applied herbicides may be beneficial as a part of a yellow nutsedge control program, but additional measures, such as a POST herbicide, would be needed for effective control. Drip-applied herbicides may give growers an option for herbicide application after drip irrigation tape and polyethylene mulch have been installed in the current vegetable crops. This application method would also allow herbicide treatment under plastic mulch used for multicropping systems.
