“…Concentrations retained on the mulch were 1/50 to 1/100 the 1× rate of dicamba and 1/500 to 1/625 the 1× rate of 2,4-D. Previous studies have noted a high level of injury and yield loss from dicamba at much lower rates than those observed on the mulch in this study when applied to the foliage of squash and cantaloupe (Culpepper and Vance 2019;Dittmar et al 2016;Hand et al 2019). Injury from 2,4-D has not been noted from rates lower than 1/300× for either cantaloupe or squash (Culpepper and Vance 2019).…”

“…Following phase out of the fumigant methyl bromide, pest management in plasticulture vegetable production has undergone significant changes (Culpepper et al 2009;Eure and Culpepper 2017;Stevens et al 2016). Fumigant systems in Georgia commonly include a combination of 1,3-dichloropropene, chloropicrin, and metam sodium injected under either lowdensity polyethylene (LDPE) mulch or totally impermeable film (Culpepper et al 2008.…”

“…Although 2,4-D and dicamba would improve preplant weed control in these systems, nontransgenic broadleaf crops are sensitive to these herbicides. Significant injury and yield reductions have been documented in bell pepper, potato, snap bean, squash, and watermelon when low rates of auxinic herbicides were applied to crop foliage (Colquhoun et al 2014;Culpepper et al 2018;Dittmar et al 2016).…”

2,4-D and dicamba removal from the surface of plastic mulch using overhead irrigation: analytical analysis and cucurbit bioassay crop response

et al. 2021

Glyphosate and paraquat are effective preplant burndown herbicide options for multi-cropped vegetable production on plastic mulch, but problematic weeds such as wild radish, cutleaf eveningprimrose, annual morningglory, or horseweed may not be adequately controlled with these herbicides alone. 2,4-D and dicamba could help control these troublesome weeds prior to planting if they can be removed from plastic mulch for avoiding crop damage. Treatments included 2,4-D (1,065 and 2,130 g ae ha−1) and dicamba (560 and 1,120 g ae ha−1) applied broadcast over plastic mulch a day before transplanting. Just before transplanting, treatments received overhead irrigation at 0.76 cm or no irrigation. Plastic mulch samples were collected at application and planting to determine herbicide presence using analytical techniques, and cantaloupe and zucchini squash were subsequently transplanted on the plastic beds. Analytical UHPLC analysis determined 88-99% of the initial herbicide concentration was present at crop planting when irrigation was not implemented. At most, a 1/50 rate of dicamba and a 1/500 rate of 2,4-D was present at planting when overhead irrigation was applied prior to transplanting. Maximum cantaloupe and squash injury from 2,4-D with irrigation was 10% and did not influence plant growth, biomass, or yield. For dicamba with overhead irrigation, cantaloupe injury reached 35%, vine lengths were reduced 24% and maturity was delayed while squash injury ranged from 9 to 12% without influencing growth or yield. Without irrigation to wash herbicides from the mulch prior to planting, 60 to 100% injury of both crops occurred with both herbicides. Zucchini squash was more tolerant to dicamba compared to cantaloupe. Results demonstrated that 2,4-D can be adequately removed from the surface of plastic mulch with irrigation while a single irrigation event was not sufficient to remove dicamba.

“…The loss of methyl bromide from the market place more than a decade ago led to a shift in weed control practices for plasticulture vegetable production systems (Culpepper et al 2009;Eure and Culpepper 2017;Stevens et al 2016). Currently, one of the most common vegetable production practices in Georgia is to fumigate using a system comprising 1,3-dichloropropene, chloropicrin, and metam sodium, while covering the bed with either low-density polyethylene mulch or totally impermeable film (TIF) Culpepper et al 2017).…”

Quantifying glyphosate plus 2,4-D or dicamba removal from the surface of totally impermeable film using analytical and bioassay techniques

et al. 2021

The loss of methyl bromide led to vegetable growers relying more heavily on herbicides to control weeds. Although herbicides can be effective, limited options in vegetable production challenge growers. Identifying new, effective tools to be applied over plastic mulch prior to planting for improved weed control with minimal crop injury would be beneficial. The objective of these experiments was to evaluate the persistence of preplant applications of glyphosate (1,125 or 2,250 g ae ha-1) plus 2,4-D (1,065 or 2,130 g ae ha-1) or dicamba (560 g ae ha-1) over plastic mulch using analytical techniques and subsequent squash and watermelon response. Glyphosate and 2,4-D were not analytically detected at damaging concentrations on plastic mulch when at least 3.5 cm of rainfall was received after application and before planting. Additionally, bioassay results for squash and watermelon supported analytical results with less than 10% visual injury for either crop, with no growth or yield suppression observed. In contrast, dicamba concentrations on plastic mulch, regardless of rainfall amount or time between application and planting, remained at damaging levels. Squash yields were reduced by dicamba applied 1 to 30 days before planting while watermelon was more resilient. 2,4-D plus glyphosate applied preplant over plastic mulch can provide an additional herbicide option for vegetable growers. Additional research is needed to understand the impact of residual activity of 2,4-D when transplants land directly in holes present in plastic mulch at the time of application. The relationship of dicamba with plastic mulch is complex as the herbicide cannot be easily removed by rainfall. Thus, dicamba should not be included in a weed management system in plasticulture vegetable production.

“…ASD with rice bran alone or preceded by incorporation of a Sudangrass cover crop and followed by drip application of molasses showed the effect on Fusarium and Pythium ultimum [22]. Plastic film on the surface of the soil serves several purposes, including optimum hydrothermal soil conditions, weed control, improvement of soil temperature [23,24]. Plastic film type such as polyethylene (PE) or totally impermeable film (TIF) showed the different efficacy on reduction emission rate of chemical fumigant (Telone C35) [25].…”

Maltose and Totally Impermeable Film Enhanced Suppression of Anaerobic Soil Disinfestation on Soilborne Pathogens and Increased Strawberry Yield

et al. 2020

Anaerobic soil disinfestation (ASD) is widely used to control soilborne diseases in organic crop production. The effect of ASD used different sealed films on soilborne pathogens and strawberry growth was evaluated in two laboratory studies and two field trials. Under maltose as carbon sources, 28 °C temperature and 30% of soil moisture optimal conditions ASD decreased Fusarium spp. and Phytophthora spp. by 100%. ASD used maltose as an organic amendment and sealed with totally impermeable film (TIF) obtained the highest suppression (>96%) against Fusarium spp. and Phytophthora spp. (>91%). According to the laboratory results, the efficacy of ASD utilizing 6 or 9 t/ha maltose and sealing with TIF was evaluated and compared with reference treatment with chloropicrin (Pic) or solarization (Sol) in the field trials. Compared with the untreated soil, ASD treatments greatly reduced the pathogenic population of Fusarium spp. and Phytophthora spp., and successfully controlled the damage of fusarium wilt with evidence of lower mortality (6%). ASD significantly increased soil nutrition promoted plant growth and increased strawberry yield, which was similar as the Pic, but better than Sol treatment. The analyzed fungal and bacterial microbiota did not show significant differences in the taxonomic richness and diversity between the compared treatments. Nevertheless, the abundance of some bacterial and fungal taxa tended to change between treated. The evidence showed that adding maltose and sealing TIF for ASD has the potential to replace Pic for pathogen control in commercial strawberry production.
