Abstract Field surveys during the 1986–87 growing season throughout the West Bank and part of the Gaza Strip concentrated on the distribution, ecology, hosts and control of the parasitic genera Orobanche (broomrape), Cuscuta (dodder), and Viscum (mistletoe). The most widespread parasitic weed is Orobanche ramosa which can attack a great diversity of hosts but is most damaging on tomato, potato, and lettuce. Orobanche crenata heavily damages broad‐bean. Control of Orobanche on large farms is almost exclusively by application of methyl bromide while small farmers attempt control with hand weeding. Cuscuta pedicellata is frequently found in lentils and Vicia sativa a widely grown fodder crop. Viscum cruciatum may be locally damaging to olive and almond but attacks a diversity of hosts. To our knowledge, this is the first survey of parasitic weeds in the West Bank and Gaza Strip.
