Technical Abstract: Vineyard replant disorder is a disease of unknown etiology described as a generic failure of young vines to thrive when planted in the same field from which an existing vineyard had been removed. While not all the causal agents of the disease have been identified, plant-parasitic nematode densities are often high in vineyard replant soils. This disease can be controlled by fumigation with methyl bromide. When nematodes are known to be the predominant pest, fumigation with 1,3-dichloropropene (1,3-D), alone or in combination with chloropicrin, can control replant disorder. Use of methyl bromide has been phased out, except for Critical Use Exemptions (CUE) or Quarantine/Preshipment (QPS) applications. Several field trials were conducted in fields following the removal of 60+ year-old vineyards. Treatments included combinations of registered and experimental fumigants, fallowing up to three years, cover crop, and resistant varieties. Nematode population density, plant vegetative growth, and berry yield were recorded up to six years after planting. The predominant nematodes present were Meloidogyne spp. and Tylenchulus semipenetrans. The benefit of multi-year fallow varied with nematode genus. Fumigation provided excellent control of nematodes. None of the rootstocks were resistant to both nematode genera. Differences in plant growth did not always result in differences in yield. Results for the combinations of treatments over time will be presented.
