Brazilian sour orange seed pelleted with inoculum of Glomus fasciculatus (Endogone fasciculata) produced mycorrhizal seedlings in greenhouse and field experiments. In the greenhouse, Arasan treatment of seed retarded and reduced mycorrhizal infection. In a nursery field fumigated with methyl bromide, seed inoculation prevented stunting and chlorosis of seedlings. Seed inoculation appears to be a practical method for obtaining mycorrhizal infection of citrus in fumigated or heat-treated soil.
