“…Previous research has demonstrated that 1,3-D + Pic is comparable with MBr + Pic for nematode control in vegetable crops, which agrees with the results found in the current study (Gilreath et al, 2004). Similarly, Gilreath et al (2005), in discussing a long-term study of fumigants on bell pepper, found that MNa + Pic was equally effective as MBr + Pic in bell pepper for sting nematode control, and provided similar fruit weight. Although high rates of propylene oxide have shown promising results against sting nematode populations in tomato (Santos and Gilreath, 2005), this fumigant underperformed for strawberry in this experiment.…”

Field studies were conducted to compare the performance of several methyl bromide (MBr) alternative programs on sting nematode (Belonolaimus spp.) control and marketable yield of ‘Camarosa’ strawberry (Fragaria ×ananassa). The tested fumigation programs were 1) MBr + chloropicrin (Pic; 67:33 v/v) at 350 lb/acre, 2) Pic + metam sodium (MNa) at 300 lb/acre and 37.5 gal/acre, 3) 1,3-dichloropropene (1,3-D) + Pic at 35 gal/acre, 4) 1,3-D + Pic and dazomet at 35 gal/acre and 200 lb/acre, 5) propylene oxide at 45 gal/acre, 6) furfural + allyl isothiocyanate (AITC) at 600 lb/acre, 7) furfural and MNa at 56 and 50 gal/acre, 8) furfural + AITC at 400 lb/acre followed by four furfural applications of 6 gal/acre/injection, 9) furfural and MNa at 37 and 33 gal/acre followed by four furfural applications of 6 gal/acre/injection, 10) fosthiazate and Pic at 4.5 and 150 lb/acre, and 11) a nontreated control. The fumigation programs consisting of 1,3-D + Pic and dazomet, 1,3-D + Pic, Pic and MNa, and fosthiazate and Pic proved to be as valuable as the grower-standard MBr + Pic on strawberry plant vigor, sting nematode control, and early and total marketable yields.

“…Commercial vegetable and strawberry production in Florida relies on the use of soil fumigation for control or suppression of soil-borne pathogens, nematodes and weeds. Growers historically relied on methyl bromide and chloropicrin combinations for pest control primarily because methyl bromide volatilized rapidly, moved readily through the soil, and controlled a broad spectrum of pests across a wide range of environmental conditions (Duniway, 2002;Gilreath et al, 2005;Locascio et al, 1997;Noling and Becker, 1994). It was classified as an ozone depleting chemical in 1993 under the Montreal Protocol and subsequent production in the U.S.…”

Placement of metam potassium in combination with dimethyl disulfide, chloropicrin, and 1,3-dichloropropene for Cyperus rotundus L. and broadleaf weed control in tomato (Solanum lycopersicum L.)

Registered fumigants tend to provide poor or inconsistent Cyperus rotundus L. and broadleaf weed control. Dimethyl disulfide (DMDS) is generally considered more effective on Cyperus species than chloropicrin (Pic) or 1,3-dichloropropene (1,3-D) whereas metam potassium is generally considered more effective on broadleaf weeds. The objective of the experiment was to determine if the use of metam potassium in conjunction with other fumigants would enhance C. rotundus and broadleaf weed control in tomato. 1,3-D+Pic caused low level crop damage in spring 2014, increased crop height in fall 2014, and had no effect on crop growth in spring 2015. In every case, differences in crop damage or height did not result in yield differences. The most effective C. rotundus control was achieved with 131 kg ha-1 1,3-D + 200 kg ha-1 Pic, 340 kg ha-1 of DMDS + 90 kg ha-1 Pic, or 392 kg ha-1 of DMDS + 195 kg ha-1 metam potassium. Metam potassium improved C. rotundus control when applied alone or in conjunction with DMDS but not when applied in conjunction with DMDS+Pic or 1,3-D+Pic. All fumigants evaluated reduced broadleaf weed density compared with non-fumigated treatments. No consistent differences in total revenues or net benefit were observed among fumigants when applied without metam potassium. The use of metam potassium increased costs per hectare although DMDS+metam potassium was cheaper then 1,3-D+Pic but not DMDS+Pic. DMDS+Pic had the lowest estimated total cost of the three best C. rotundus treatments.

“…The search for alternative chemical treatments has included evaluation of new or old materials and alternative application methods for currently registered or nonregistered fumigants that have potential to be alternatives to MBr. Metam sodium (MS), 1,3dichloropropene (1,3-D), and Pic are currently registered in the United States and have provided nematode, pathogen, or weed control in trials in various production systems (DeCal et al, 2004;Gilreath et al, 2005;Karlik et al, 2001;Mann et al, 2005;Stanghellini et al, 2003). Nematode contol results in the literature with drip-applied MS are inconsistent (Overman, 1982;Overman et al, 1987;Roberts et al, 1988).…”

Field studies were conducted to evaluate potential alternatives to methyl bromide (MBr) for the control of plant parasitic nematodes in shallow-rooted, bedded cropping systems such as strawberry and in perennial nursery cropping systems in central California. Chloropicrin (Pic), 1,3-dichloropropene (1,3-D or Telone), combinations of 1,3-D + Pic, iodomethane (IM) + Pic, propargyl bromide (PBr), and metam sodium (MS) were compared with untreated controls and industry standard MBr/Pic treatments. Materials were applied by both shank-injection and drip-application, except MS and PBr, which were applied only by drip. The efficacy on citrus nematode (Tylenchulus semipenetrans Cobb) and/or root-knot nematode (Meloidogyne spp. Chitwood) control was investigated in three trials conducted on soils ranging from sandy loam to silty clay loam. All treatments controlled nematodes near the injection point (center of bed and moderate depths) comparable to MBr/Pic. Drip-applied Pic provided somewhat less control than MBr/Pic at the shoulder of the bed when delivered in 25 mm of water and MS provided no control at the bed shoulder. IM + Pic, both shank-injected and drip-applied, provided nematode control to a depth of 150 cm comparable to MBr/Pic. Telone EC applied to a dry field in 75 mm water did not control nematodes well at either 90- or 150-cm depths, whereas PBr controlled nematodes as effectively as MBr/Pic at the 90-cm depth, but not at the 150-cm depth. Propargyl bromide at 67 kg·ha−1 was effective at killing the nematodes up to 30 cm deep in a strawberry plant bed. The dosage exposure values (within 96 h after fumigation) observed for greater than 99% control of nematodes were much lower for PBr (≈1 mg·L−1·h) than those for 1,3-D + Pic (17 mg·L−1·h when applied at 61:35 1,3-D:Pic mass ratio), Pic alone (10 mg·L−1·h), and IM + Pic (19 mg·L−1·h when applied at 50:50 mass ratio). Drip application technology showed promise for effective alternatives to MBr/Pic. Consistent delivery of an effective dosage of a material throughout the target soil profile is necessary for consideration as an acceptable alternative to MBr for high-value crops.
