“…Application of oxyfluorfen at 400 g•ha −1 resulted in the weed control of more than 90 per cent of weeds, but the herbicide inhibited the crop growth. Several research findings showed that oxyfluorfen has successfully controlled broad leaved weeds in vegetable systems including broccoli [8], onion [9], chilli pepper [10], cauliflower [11] and cabbage [12]. Pre-emergence application of oxyfluorfen most effectively decreased the number of annual broad leaved weeds in onion and cabbage [13].…”

“…The crop injury was transient and appeared stunted for one month, after that the crop appeared normal. The pre-emergence application of oxyfluorfen at 300 to 600 g•ha −1 resulted in 30 per cent injury in strawberry [18]. The post-emergence application of oxyfluorfen at 150 g•ha −1 showed phytotoxicity symptoms in pea [19].…”

A field experiment were conducted for two years at Agricultural Research Station, Bhavanisagar of Tamil Nadu Agricultural University, during kharif season of 2009 and 2010 to evaluate the new formulation of oxyfluorfen (23.5% EC) on weed control in onion. Weeds constitute one of the biggest problems in agriculture that not only reduce the yield and quality of onion but also utilize essential nutrients. Hence, weed control is essential for increasing onion production. Based on two years field experimentation, it was found that pre-emergence application of oxyfluorfen (23.5% EC) at400 g^.ha^-¹ gave significantly lower total weed density, weed dry weight and higher weed control efficiency at all the intervals. Application of new formulation of oxyfluorfen (23.5% EC) at200 g^.ha^-¹ as pre-emergence herbicide can keep the weed density and dry weight below the economic threshold level and increase the bulb weight (42.56 and43.87 g) and yield (15940 and15610 kg^.ha^-¹) in onion. Unweeded control accounted for lower bulb yield which inturn reflected through higher weed index of 60.6 and 56.1 per cent, respectively during both the years, due to heavy competition of weeds for nutrients, space and light.

“…A number of pre‐emergent (PRE) herbicides have been evaluated for use in strawberry . Previous studies demonstrated strawberry tolerance to PRE applications of S‐ethyl dipropylthiocarbamate (EPTC), fomesafen, pendimethalin, prodiamine, napropamide and oxyfluorfen . However, control of weeds with these PRE herbicides in strawberry has been inadequate or inconsistent .…”

BACKGROUND Ethanedinitrile (EDN) has shown promising efficacy against weeds, plant‐parasitic nematodes and soil‐borne pathogens. Field experiments were conducted for three strawberry (Fragaria× ananassa D.) seasons in Balm and Dover, FL, USA to evaluate the control efficacy of EDN applied through drip tape on various weed species and the fungus Macrophomina phaseolina, the causal agent of charcoal rot of strawberry. RESULTS Results revealed that 224, 336, 448 or 560 kg ha−1 EDN, and 104 kg ha−1 1,3‐dichloropropene (1,3‐D) + 176 kg ha−1 chloropicrin (Pic) applied through drip tapes under totally impermeable film were safe for strawberry production, with no adverse effect on strawberry growth and yield. EDN rates at 224, 336, 448 and 560 kg ha−1 were highly efficacious and equally effective in reducing purple nutsedge (Cyperus rotundus L.) in two of three growing seasons. Compared with the efficacy on purple nutsedge, the evaluated EDN rates were generally less effective on various broadleaf and grass weeds emerging on the bare ground and planting holes, but at 560 kg ha−1 consistently exhibited similar levels of control as 1,3‐D + Pic. For M. phaseolina, the evaluated EDN rates were more efficacious than 1,3‐D + Pic and significantly reduced inoculum buried in different bed locations in plastic‐mulched beds. CONCLUSION EDN has potential to be an efficacious tool for soil disinfestation and weed control in plasticulture strawberry production. © 2019 Society of Chemical Industry

Herbicides can be an excellent supplemental treatment in cases where soil fumigant treatments alone fail to control weeds during the growing season or in situations where fumigants cannot be used as a result of regulatory restrictions. Previous studies have shown that oxyfluorfen and flumioxazin can provide satisfactory weed control in bedded strawberry (Fragaria ×ananassa Duch.) production. However, we need to know if tolerance to herbicides is uniform across strawberry cultivars under California conditions. The objective of this study was to determine if tolerance to oxyfluorfen and flumioxazin herbicides varied among strawberry cultivars. Trials were conducted in the 2007–2008 and 2009–2010 growing seasons at Salinas, CA. Treatments included an untreated control; pre-plant applications of flumioxazin at 0.07, 0.11, and 0.21 kg·ha−1 a.i.; and oxyfluorfen at 0.14 and 0.28 kg·ha−1 a.i. The entire trial was fumigated with an emulsified formulation of 60% 1,3-dichloropropene + 32% chloropicrin applied at 281 L·ha−1 by drip injection to all plots. Eight strawberry cultivars were included in the trial in the 2007–2008 growing season, and nine cultivars were included in the 2009–2010 growing season. In both growing seasons, slight to no crop phytotoxicity was observed. In the 2007–2008 growing season, several strawberry cultivars including ‘Albion’, ‘Festival’, ‘211G51’, ‘Palomar’, ‘Plant Sciences 5298’, and ‘Ventana’ had smaller crop plant canopy diameter as compared with the control when treated with 0.21 kg·ha−1 a.i. of flumioxazin. Compared with the control, flumioxazin at 0.21 kg·ha−1 a.i. reduced crop diameter for ‘Plant Sciences 4634’, ‘Plant Sciences 5298’, ‘San Andreas’, and ‘Ventana’ in the 2009–2010 growing season. In the 2007–2008 strawberry-growing season, none of the herbicide treatments reduced fruit yield compared with the control. In the 2009–2010 growing season, in seven of the nine cultivars, there were no significant differences in yield among treatments. For ‘Palomar’ strawberry, yields in plots treated with flumioxazin at 0.11 and 0.21 kg·ha−1 a.i. were significantly lower than the untreated control. With the exception of flumioxazin at 0.21 kg·ha−1 a.i., these herbicides are safe to use and can be incorporated in strawberry production practices for the cultivars tested to achieve satisfactory weed control over the growing season.
