Abstract

Surveys in central Washington have associated several genera of plant-parasitic nematodes with Concord grapevines (Vitis labrusca L.) exhibiting poor growth. Plant parasitic genera of suspected importance were Macroposthonia, Meloidogyne, Pratyienchus and Xiphinema, which have been reported to damage grapevines (Raski, et ai., 1973, Santo and Bolander, 1977, Santo and Hackney, 1980). Before it was banned DBCP (l,2-dibromo-3-chloropropane) was widely used in established V. vinifera L. vineyards to control nematodes (Raski, 1962, Raski, et ai., 1973), but it was not used in Washington on V. iabrusca. Studies were initiated to determine the effects of nematodes on Concord grapes and the efficacy of DBCP for their control. Preliminary studies with DBCP on Concord grapes were reported (Santo, 1978).
