Non-chemical strategies for plant parasitic nematode management allow for the development of alternative integrated pest management strategies. Cover crops, fallow periods and Vitis spp. rootstocks are such strategies, and were evaluated for their ability to reduce soil-borne Meloidogyne hapla (northern root-knot nematode). This nematode is the primary plant parasitic nematode of concern in Washington's own-rooted Vitis vinifera vineyards. Cover crops were evaluated both in pre-plant and post-plant vineyard scenarios. In pre-plant scenarios, litchi tomato (Solanum sisymbriifolium) was evaluated as previous studies against other nematode species demonstrated its efficacy. In this study, litchi tomato was able to significantly reduce the population density of M. hapla in the soil relative to a weedy fallow pre-plant ground cover. 'Dracula' oilseed radish (Raphanus sativus), 'Pacific Gold' mustard (Brassica juncea) and 'Dutch White' clover (Trifolium repens) were evaluated as cover crops for post-plant management of M. hapla. While all three crops reduced M. hapla populations relative to weedy fallow ground cover in field studies, 'Dracula' oilseed radish reduced M. hapla populations most significantly. A survey of fallow sites across eastern Washington, which were previously planted to V. vinifera, showed that a period of fallow for at least one calendar year was needed to reduce populations densities of M. hapla in the soil. Other management strategies that were applied to these sites during their fallow period, such as the use of cover crops, irrigation, herbicide, or tillage during the fallow period did not significantly reduce M. hapla populations. Finally, Vitis spp. rootstocks were evaluated in greenhouse experiments. Nine different Vitis spp. rootstocks were assessed for their ability to host M. hapla, and own-rooted V. vinifera 'Cabernet Sauvignon' and 'Chardonnay' served as susceptible controls. While all non-vinifera rootstocks hosted statistically fewer M. hapla than the V. vinifera controls, the non-vinifera rootstocks were not entirely immune from nematode feeding and reproduction. Short-term greenhouse experiments can be useful in evaluating the ability of nematodes to feed and reproduce on a genotype but cannot determine if feeding will result in a change in phenotype (i.e., reduced growth or yield) over the lifespan of a vineyard.Individually, the adoption of a cover crop, the use of a fallow period between vineyard replanting, or the adoption of a rootstock might not provide complete mitigation of M. hapla damage to grapevines. However, when combined, they have the potential to provide effective, long-term, non-chemical management of this plant parasitic nematodes in vineyards.
