Fungus Pathogens in Forest Nurseries
The mere presence of a fungus pathogen in your nursery should be of little concern to you until the fungus infects a crop plant and causes appreciable damage. A fungus pathogen may cause disease of such non-crop plants as nutgrass, crabgrass, or dog fennel. The brown spot fungus is probably in many of your nurseries during most years but causes little if any real damage to your loblolly or slash pine crops. Ferbam sprays offer some degree of control of this pathogen in slash and loblolly but Bordeaux mixture may be needed to control this disease in longleaf plantings.
