Effects of methyl bromide on antibiotic production by Armillaria mellea

Abstract: Two isolates of Armillaria mellea (Vahl ex Fr.) Kummer produced in vitro , substances inhibitory to strains of Streptococcus sp., Mucor sp., Trichoderma longibrachiatum , Rifai aggr., T. harzianum , Rifai aggr., Rhizopus stolonifer (Ehrenb. ex Fr.) Lind, Fusarium solani (Mart.) Sacc, F. roseum , Link ex Fr. and to one of two strains of Gliocladium virens , Miller, Giddens & Foster. Antibiotic production was reduced by fumigation of inoculae of A. mellea with sublethal concentrations of methyl bromide. It is suggested that in these conditions, A. mellea is predisposed to subsequent parasitic attack associated with the biological control of A. mellea often reported after fumigation.
