NO IT IS NOT - the initial problem is fungal - then if the skin is broken - from horse rolling in dirt, scratching to relieve the intense itch or the owner picks off the scabs then you risk bacterial infection and then you require both an antifungal and antibacterial treatment.
Rain rot/mudfever/greasy heal are not normal scabs - they are made up of lymph that has oozed through the skin as a result of the fungus, the lymph then congeals around the hairs developing a locked on tight scab. If you forcibly remove the scab you pull hair directly out of the skin by its roots, because the skin is already compramised by the fugus it breaks open and bleeds.
Treat with a fungal shampoo the moment you feel the lumps will generally clear it really fast.
