Diseases of melon ( Cucumis melo ) in Arizona Alternaria leaf spot Alternaria leaf spot is caused by the fungus Alternaria. The fungus produces dark‚ multicelled spores on host tissue only when there is substantial moisture‚ usually during summer rains. The spores are easily carried in wind and splashing water and infect only the leaves. Brown necrotic spots appear on the leaves wherever spores germinate and infect leaf tissue (photo 1). Spots are small at first then may enlarge and coalesce to

against Blastomyces dermatitidis Blastomyces dermatitidis is a type of pathogenic fungus which causes Blastomycosis‚ a yeast-likeyeastlike infection which occurs most frequently in dogs. It is seen most often in large breed male dogs‚ and especially in hunting dogs‚ sporting breeds‚ and dogs that spend a lot of time in environments where the Blastomyces organism exists‚ but female dogs are also susceptible. This fungus is commonly found in decaying wood and soil‚ especially in places with a wet environment

that grow on plants. It is difficult to distinguish between the two without proper inspection and diagnosis of the diseased plant to know whether the bacteria or the fungus in question is the virulent or non-virulent one. Therefore pure cultures need to be isolated to know with absolute certainty which is the causative bacteria or fungus. Potato dextrose agar is a good nutrient agar for mycelia to thrive on which is present in most fungal moulds.1 Standard nutrient agar is a general utility used
