subsurface drip application of alternative fumigants to Methyl Bromide for controlling nematodes in replanted grapevines
Pest Management Science, 2012Co-Authors: Sally M Schneider, Bradley D Hanson, Alfonso J Cabrera, Dong WangAbstract:BACKGROUND: Many California grape growers use preplant fumigation to ensure uniform and healthy grapevine establishment in replant situations. A field study was conducted to evaluate the performance of subsurface drip-applied chemical alternatives to Methyl Bromide on plant-parasitic nematodes, plant vigor and fruit yield during the 6 year period following replanting. RESULTS: Subsurface drip fumigation with 1,3-dichloropropene plus chloropicrin and with iodomethane plus chloropicrin had generally similar nematicide activity as Methyl Bromide in three grape types, while sodium azide was less effective. The combination of 1,3-dichloropropene plus chloropicrin enhanced vine vigor similarly to Methyl Bromide. However, all plots treated with alternative fumigants produced less fruit yield than Methyl Bromide over the 4 years of evaluation. CONCLUSION: Subsurface drip fumigation with alternative chemicals to Methyl Bromide generally provided adequate management of plant-parasitic nematodes during the vine establishment period. However, further research is required to increase the performance of alternative chemicals against other components of the replant problem, as grape yield in vines grown in the alternative treatments was lower than in Methyl Bromide.

comparison of shank and drip applied Methyl Bromide alternatives in perennial crop field nurseries
Horttechnology, 2009Co-Authors: Sally M Schneider, Bradley D Hanson, James S Gerik, Anil Shrestha, Thomas J Trout, Suduan GaoAbstract:Methyl Bromide has been used extensively in open-field perennial crop nurseries to ensure the production of plants that are free of soilborne pests and pathogens. California regulations require that nursery stock for farm planting be commercially clean with respect to economically important nematodes. Under the terms of the Montreal Protocol, the use of Methyl Bromide by developed countries was phased out 1 Jan. 2005. Although the perennial nursery industry in the United States largely continues to use Methyl Bromide under critical use exemptions and quarantine/preshipment criteria allowed under provisions of the Montreal Protocol, nursery growers need viable alternatives to this fumigant. Two fumigation trials in perennial crop field nurseries with sandy loam and clay loam soils, respectively, were conducted to compare the efficacy of fumigants applied through standard shank-injection equipment or as emulsifiable compounds applied through drip irrigation equipment. In the garden rose (Rosa multiflora) nursery trial, nematodes were detected at planting in the untreated control, no-tarpaulin 1,3-dichloropropene + chloropicrin, and chloropicrin alone several months after treatment. Nematodes included root-knot nematode (Meloidogyne spp.) and stunt nematode (Tylenchorhynchus semipenetrans). At harvest 2 years later, root-knot nematode was detected in rose roots from untreated plots and plots treated with untarped 1,3-dichloropropene + chloropicrin, metam sodium, and chloropicrin alone. In the nut tree (Prunus spp.) nursery field trial, shank-injected treatments typically provided better nematode control than the same chemicals applied via the drip lines, although weed control and marketable trees were similar among treatments.

perennial crop nurseries treated with Methyl Bromide and alternative fumigants effects on weed seed viability weed densities and time required for hand weeding
Weed Technology, 2008Co-Authors: Anil Shrestha, Sally M Schneider, Greg T Browne, Bruce D Lampinen, Leo Simon, Thomas J TroutAbstract:Data on the efficacy of alternative fumigants to Methyl Bromide for weed control in perennial crop nurseries in California are needed because few herbicides are registered for this purpose. Field studies were conducted from 2003 to 2006 in four commercial perennial crop nurseries in California. Treatments included a nonfumigated control; Methyl Bromide (98%) (MeBr) with high-density polyethylene (HDPE) film; iodomethane (50%) + chloropicrin (50%) with HDPE film; 1,3dichloropropene (1,3-D) with HDPE film; 1,3-D (61%) + chloropicrin (35%) with HDPE film; 1,3-D (62%) + chloropicrin (35%) subsurface drip; and 1,3-D (61%) + chloropicrin (35%) with virtually impermeable film (VIF). All the fumigants reduced the seed viability of common purslane, johnsongrass, and tall morningglory but were not as effective on little mallow and field bindweed. Although total weed densities and the level of control provided by each fumigant differed between locations, weed density was generally reduced by all the fumigation treatments, compared to the nonfumigated control. At three locations, alternative fumigation treatments usually resulted in hand-weeding time similar to MeBr. Reductions in weed seed viability, weed emergence, and weed densities suggest that these alternative fumigants will provide weed control similar to MeBr in perennial nurseries. Nomenclature: 1,3-dichloropropene; chloropicrin (trichloronitromethane); iodomethane; Methyl Bromide; common purslane, Portulaca oleracea L. POROL; field bindweed, Convolvulus arvensis L. CONAR; little mallow, Malva parviflora L. MALPA; johnsongrass, Sorghum halepense (L.) Pers. SORHA; tall morningglory, Ipomoea purpurea (L.) Roth PHBPU.

united states department of agriculture agricultural research service research on alternatives to Methyl Bromide pre plant and post harvest
Pest Management Science, 2003Co-Authors: Sally M Schneider, Carolee Theresa Bull, Dan O. Chellemi, Erin N Rosskopf, James G. Leesch, Mark MazzolaAbstract:Methyl Bromide is a widely used fumigant for both pre-plant and post-harvest pest and pathogen control. The Montreal Protocol and the US Clean Air Act mandate a phase-out of the import and manufacture of Methyl Bromide, beginning in 2001 and culminating with a complete ban, except for quarantine and certain pre-shipment uses and exempted critical uses, in January 2005. In 1995, ARS built on its existing programs in soil-borne plant pathology and post-harvest entomology and plant pathology to initiate a national research program to develop alternatives to Methyl Bromide. The focus has been on strawberry, pepper, tomato, perennial and nursery cropping systems for pre-plant Methyl Bromide use and fresh and durable commodities for post-harvest use. Recently the program has been expanded to include research on alternatives for the ornamental and cut flower cropping systems. An overview of the national research program is presented. Results from four specific research trials are presented, ranging from organic to conventional systems. Good progress on short-term alternatives is being made. These will be used as the foundation of integrated management systems which begin with pre-plant management decisions and continue through post-harvest processing.

Nonfumigant alternatives to Methyl Bromide for management of nematodes, soil-borne disease, and weeds in production of snapdragon (Antirrhinum majus)
International Journal of Pest Management, 2009Co-Authors: Robert Mcsorley, Erin N Rosskopf, Koon-hui Wang, Nancy Kokalis-burelle, H.n. Hans Petersen, Harsimran K. Gill, R. KruegerAbstract:Two field experiments were conducted in north Florida to examine effects of solarization and reduced-risk pesticides on weeds, nematodes, soil-borne diseases, and yield of snapdragon (Antirrhinum majus). Five treatments were replicated five times in a randomized complete block design: fumigation with 80:20 Methyl Bromide:chloropicrin, solarization, solarization + Kodiak® (product with Bacillus subtilis), solarization + Biophos™ (product with dipotassium phosphonate and dipotassium phosphate), and non-treated control. Methyl Bromide was generally superior to treatments involving solarization, which in turn were superior to the control, for improving flower yield and managing weeds, nematodes, and mortality due to plant disease. In the second year, solarization was more effective than Methyl Bromide in reducing plant mortality; however, surviving plants were larger and more productive following Methyl Bromide. In the second year, Biophos™ + solarization was as effective as Methyl Bromide in improving plant ...
