- Abstract
Fungicides were compared for the control of the mushroom pathogens Verticillium fungicola (dry bubble disease), Mycogone perniciosa (wet bubble disease) and Hypomyces rosellus (cobweb disease). Prochloraz, applied as a manganese complex, consistently gave significantly greater control of a benomyl-resistant strain of V. fungicola. Captafol gave some reduction in disease. Benomyl thiabendazole and prochloraz all gave significant control of M. perniciosa and H. rosellus. Prochloraz residues in mushrooms were measured by gas chromatography after extraction in acetone and purification by means of solvent partition. When pure prochloraz was added to homogenized mushroom tissue, 77–98% was recovered by this procedure. The residue levels in sporophores from crops treated with prochloraz were low. Prochloraz appears to be an effective fungicide for the control of the major fungal pathogens of the mushroom crop, particularly where benzimidazole-resistant strains of V. fungicola occur.
