FW, VW, SSB, and RKN can be well managed using standard fumigants. Alternative management practices are needed in production systems where fumigants are not used or effective, and/or where heirloom tomato cultivars are grown. We are involved in a USA multi-state program to determine the viability of grafting in open-field production systems. Previously published work showed the utility of grafting to manage FW, SSB, RKN, and BW. In complementary work to manage BW, a replicated on-farm field trial demonstrates that fumigants such as Paladin (79% dimethyl disulfide + 21% chloropicrin) and PicClor60 (60% chloropicrin + 40% 1,3-dichloropropene) allow up to 80% plant death, similar to incidence in non-fumigated plots, whereas grafting to resistant rootstock (Seminis 'Cheong Gang') confers 100% control in non-fumigated plots. Another on-farm randomized complete block design experiment demonstrated that three commercially available rootstocks conferred 100% plant stand, whereas non-grafted plants had 80% plant death using a round tomato scion ('Red Mountain') or 15% plant death using a roma tomato ('Picus'). Grafted plants show economic viability in North Carolina, and additional work is needed to optimize this tool in diverse production systems.}, number={1207}, journal={Acta Horticulturae}, publisher={International Society for Horticultural Science (ISHS)}, author={Louws, F.J. and Suchoff, D. and Kressin, J. and Panthee, D. and Driver, J. and Gunter, C.}, year={2018}, month={Jul}, pages={249–254} }
