Brussels sprouts are susceptible to 3 commonly occurring species of root knot nematide in greenhouse tests. These nematodes caused root galling and suppressed shoot growth by up to 36%. Root galling was more severe from M.incognita and M.javanica than from M.hapla which indicates that growers should not reply on the presence of galling to diagnose nematode damage. Two strains (a brassica strain and a non-brassica strain) of Verticillium dahliae, the soil-borne fungus which causes the disease Verticillium Wilt, were tested for pathogenicity to Brussels sprouts in the greenhouse.
