“…Halosulfuron controls nutsedge when applied to the soil or on the foliage (Shaner 2014;Vencill et al 1995;Yu and Boyd 2017). Tomato plants are tolerant to halosulfuron at 26 to 52 g ai ha −1 when applied topically (Buker et al 2004;Chaudhari et al 2016a;Monday et al 2015;Mohseni-Moghadam and Doohan 2017b). Currently, halosulfuron is registered for PRE or POST over-the-top application from the 4-leaf stage until 30 d prior to harvest.…”

Purple nutsedge is a troublesome weed in tomato grown in plasticulture systems. Field trials were conducted in the fall of 2017 and spring of 2018 at Balm, FL, to evaluate multiple herbicide programs applied pretransplanting (pre-T), post-transplanting (post-T), and pre-T followed by (fb) post-T for purple nutsedge control in plasticulture tomato. Pre-T treatment of sulfentrazone or S-metolachlor alone were ineffective and did not decrease purple nutsedge density compared with the nontreated control. Post-T application of halosulfuron did not reduce purple nutsedge density at 12 wk after initial treatment (WAIT) in fall 2017 but reduced the purple nutsedge density at 17 WAIT in both seasons. Pre-T sulfentrazone or S-metolachlor application fb halosulfuron applied post-T were the most effective treatments and consistently reduced purple nutsedge population in both seasons. Herbicide treatments did not injure or reduce tomato height or yield. Overall, these results suggest sequential herbicide programs, including pre-T application of sulfentrazone or S-metolachlor fb post-T application of halosulfuron generally resulted in greater purple nutsedge control compared with pre-T or post-T application only. Halosulfuron applied post-T is critical to provide season-long purple nutsedge control in plasticulture tomato.

“…This difference appears to be primarily due to a reduction in the yield of extra large fruit; there were no differences in yield in the medium and large grade. The yield reduction was unexpected, as previous research has shown that halosulfuron is safe for use in fresh-market tomato (Dittmar et al 2012; Jennings 2010), but crop tolerance has been shown to vary with cultivar (Mohseni-Moghadam and Doohan 2017). The halosulfuron label specifically instructs against applying following bloom unless crop shields are in place or the spray is directed away from the plant (Anonymous 2015).…”

“…POST-directed herbicides such as imazosulfuron, halosulfuron, and trifloxysulfuron can be safely applied to tomato (Jennings 2010). In Florida, halosulfuron is the most common POST-directed herbicide applied for nutsedge control in tomato, but crop tolerance can vary with cultivar (Mohseni-Moghadam and Doohan 2017).…”

Purple nutsedge is difficult to control in vegetable plasticulture due to its ability to penetrate the plastic mulch. Experiments were conducted in Spring 2011 and 2012 at the Plant Science Research and Education Center in Citra, Florida, and in Spring and Fall 2013 at the Gulf Coast Research and Education Center in Balm, Florida. The objective was to determine tomato (cv. Amelia, Charger, and Florida 47) tolerance and purple nutsedge response to herbicides and herbicide tank-mixes applied POST-directed to base of tomato. Chlorimuron-ethyl, flazasulfuron, fomesafen, halosulfuron, imazosulfuron, rimsulfuron, nicosulfuron, and trifloxysulfuron applied POST-directed to the base of the crop did not cause crop damage. Halosulfuron or tank-mixes that contained halosulfuron tended to provide the greatest nutsedge suppression in all experiments. Halosulfuron or nicosulfuron+rimsulfuron applications when tomato (cv. Charger) were flowering reduced marketable yields by 22-28% compared to the nontreated control. No yield reductions occurred with Florida 47 or Amelia cultivars. Flazasulfuron provided similar purple nutsedge suppression to halosulfuron and did not damage tomato. Tank-mixes that contained halosulfuron tended not to provide any added benefit over halosulfuron alone. This research identified herbicides that are safe for use as a POST-directed application in tomato. Additional research is needed to evaluate efficacy of these herbicides on broadleaf weeds.

“…Visual crop injury symptoms, including stunting, epinasty, foliage deformations, and chlorosis, were determined and rated using a 0% to 100% scale, with 0% being no injury and 100% being total crop death [29]. Data were collected 3 and 6 weeks after treatment (WAT).…”

“…Interestingly, all cultivars completely recovered from injury until 6 weeks after treatment (WAT) [28]. In another study, the tolerance of some tomato varieties to halosulfuron-methyl was assessed by exposition to the drift rates of 0, 34.7, and 70 g ae ha −1 [29]. At 6 WAT, of seven tomato varieties, E6203 displayed the most visual injury to halosulfuron-methyl at 70 g ae ha −1 in the first year of the experiment; however, all other varieties recovered from herbicide injury [29].…”

One of the most widely used auxinic herbicides in southern Iran’s cereal crop fields is 2,4-D; however, the concurrent growing season of off-season melons in this region potentially leads to herbicide drift from cereal fields to the melon fields. To study the response of some Iranian wild melon accessions to three simulated drift rates of 2,4-D, including 112.1, 11.2, and 3.7 g ae ha−1, a field experiment was conducted during 2019 and 2020 growing seasons. It was found that by increasing the herbicide rate from 3.7 to 112.1 g ae ha−1, the level of visual injury increased in all accessions. However, significant variation in herbicide tolerance was observed among different melon accessions. The MEL-R1 was the most tolerant accession with only 20% injury, while MEL-D8 displayed very high injury rate (ca. 90%) as assessed at 6 weeks after treatment during 2019. The accession MEL-S3 was the most tolerant to 2,4-D drift rates (20% injury) at 6 weeks after treatment during 2020. There was no significant difference between the accessions MEL-R1 and MEL-S3 in terms of their response to 2,4-D treatment during both years of the study, as these accessions fully recovered from injury over 6 weeks after herbicide treatment. In addition, only these two accessions were able to produce yield after the application of 2,4-D at the highest rate tested (112.1 g ae ha−1). Therefore, the melon accessions MEL-R1 and MEL-S3 could be recommended for cultivation and even for breeding programs in order to develop 2,4-D-tolerant commercial cultivars in regions where this herbicide is commonly used in cereal crop production adjacent to the melon fields.
