Summary We studied the effects of field application rates of three fungicides on spore germination and root infection in three species of Glomus. Bavistin (carbendazim) prevented germination of spores of G. monosporum and G. mosseae whereas Calixin (tridemorph) had no effect. Tilt Turbo (propiconazole) inhibited spore germination less than Bavistin. Spores of G. geosporum germinated in the presence of all three fungicides. Foliar applications of Bavistin alone and in a triple-spray programme significantly reduced infection of all three Glomus species in wheat roots grown in conditions of low P availability (2 mg P 1−1). Two fungicides with triazole derivatives, Sportak and Tilt Turbo, also decreased infection and the former significantly reduced spore production of all three Glomus species. Calixin-treated plants, however, showed increased infection levels, resulting in greater yields and greater foliar-P concentrations than control plants. Milgo (ethirimol) was not detrimental to the vesicular-arbuscular mycorrhizal (VAM) symbiosis when applied as a foliar spray.
