“…Until recently, the only non‐fumigant nematicide available to vegetable growers in Florida was oxamyl, a carbamate insecticide/nematicide, but it is now a restricted use pesticide. Soil fumigation with products like 1,3‐dichloropropene, metam, chloropicrin, and dimethyl disulfide often provides acceptable nematode control . There are, however, limitations and restrictions that pose problems for the use of soil fumigants, such as: (i) restricted use pattern in the southern most region of Florida in order to protect ground water, (ii) worker protection issues, (iii) plant‐back times to avoid phytotoxicity, (iv) set back distances from dwellings, and (v) mandatory fumigant management plans .…”

BACKGROUND Two field experiments were conducted to determine the efficacy and field performance of three new non‐fumigant chemical nematicides (fluensulfone, fluopyram, and fluazaindolizine) and two biological nematicides (Burkholderia rinojensis strain A396 and Purpureocillium lilacinus strain 251) for management of root‐knot nematodes (Meloidogyne javanica) on tomato and associated double‐crops in Florida. RESULTS In experiment 1, soil fumigation with metam potassium increased plant growth and reduced root galling on tomato by 77% relative to that of the untreated soil. All non‐fumigant chemical nematicides reduced root galling on tomato (47–85% reduction); however, only fluensulfone showed a trend towards yield enhancement. In experiment 2, soil fumigation with chloropicrin increased plant growth and reduced root galling on tomato by 35% relative to that of the untreated soil; however, end‐of‐season populations of M. javanica in soil were larger than that of the non‐fumigated soil. Fluensulfone showed a trend towards reduced root galling and enhanced fruit yield, whereas other non‐fumigant nematicides did not. Double‐cropped cucumber was 69% more galled when planted into soil previously fumigated with chloropicrin relative to that of untreated soil, and also showed reduced plant vigor and fruit yield. CONCLUSION Fluensulfone shows significant potential to be a component of an integrated pest management strategy for tomato in Florida. © 2019 Society of Chemical Industry

“…Although successful nematode controls have been reported in cucumber using soil fumigants and contactsystemic nematicides (Giannakou et al, 2002;Giannakou and Karpouzas, 2003;Gilreath et al, 2004) and more environmentally friendly compounds like essential oils extracted from aromatic plants (Oka et al, 2000), dry mycelium of Penicillium chrysogenum, a waste product of the pharmacological industry (Gotlieb et al, 2003), or extracts of Inula viscose, a perennial plant that is widely distributed in Mediterranean countries (Oka et al, 2006), deployment of resistance gene is by far the most economical alternative. Hence, AFLP and SRAP-SCAR markers were used to develop molecular markers to mj gene.…”

Root-knot nematodes (Meloidogyne spp.) are an important worldwide pest of cucumber (Cucumis sativus L.). Molecular markers linked to the Javanese root-knot nematode (M. javanica) resistance gene mj in cucumber may aid marker assisted selection. One-hundred AFLP (EcoRI-MseI) and 112 SRAP were used to screen resistant and susceptible parents for polymorphisms to develop molecular markers linked to the mj gene. Of the 100 AFLP primers, 92 produced bands and two yielded candidate markers (E-ATT/M-CAA and E-AAC/M-CTG). These two bands were cut off from polyacrylamide gel, cloned and sequenced. Primers designed from the sequences did not yield polymorphic bands between the parents. In addition, the sequences did not contain any restriction site or indel to be used to convert them to CAPS or SCAR markers. The two sequences obtained from polymorphic AFLP markers were used primarily to design D1F, D1R, D17F and D17R primers. SRAP forward and reverse primers were used in combination with these four specific primers to search for polymorphisms between parents. Of the 112 primer combinations 11 yielded polymorphisms between parents. MapMaker Exp 3.0 software was used to analyze the 11 markers. Two markers were identified that flanked the mj gene at distance of 16.3 and 19.3 cM. The results indicated that these markers should be useful to develop molecular markers flanking the mj gene.

“…However, its registration and usage in the United States was officially phased out by EPA on 1 January 2005 due to ozone depletion. Many research studies have been conducted to find alternatives for methyl bromide for various agronomic and horticultural crops (4,5,6). Previous research has indicated several fumigants or fumigant combinations have the potential to be used as methyl bromide alternatives in weed control.…”

Field research was conducted at Auburn University Turfgrass Research Unit, Auburn AL, from 2008 to 2010 to evaluate EPTC (S‐ethyl‐N,N‐dipropylcarbamothioate) as a preplant soil treatment in warm‐season sod production and to determine minimum plant‐back intervals for ‘Palmetto’ St. Augustinegrass and ‘BK‐7’ zoysiagrass. In 2008 and 2009, EPTC and EPTC plus dazomet treatments consistently resulted in lower St. Augustinegrass dry weight than other treatments when stolons were planted one week after treatment (1 WAT). St. Augustinegrass planted 1 WAT had similar or significantly higher dry weights and average stolon lengths than those planted 2 or 3 WAT. Chemical treatments did not affect zoysiagrass growth in 2009, although the EPTC produced the lowest dry weights when zoysiagrass stolons were planted 1 WAT or 3 WAT in 2008. Plant‐back interval comparisons suggested zoysiagrass could be planted back 1 week after EPTC and EPTC plus dazomet treatment without receiving significant injury. Addition of fumigant dazomet with EPTC did not adversely affect St. Augustinegrass dry weight more than EPTC applied alone. Similar results were also found in the cucumber bioassay, in which there were no significant cucumber dry weight differences within EPTC and EPTC plus various rates of dazomet. GC‐MS analysis of EPTC retention under field conditions indicated EPTC applied at 7.8 kg ai/ha in July was nearly completely degraded in the top 7.5 cm soil within 7 days.
