Nursery Diseases of Southern Hardwoods

Abstract

Numerous diseases may be encountered in hardwood plantings in Southern nurseries. Although severe disease losses have been observed in only a few hardwood species, some loss occurs in nursery plantings of all species and can be expected to continue. The lack of an effective post-emergence herbicide to control weeds in hardwood nursery seedbeds and the high cost of hand weeding has made preplanting soil fumigation -which controls not only weeds but also soil-borne diseases-a common and economically feasible practice in Southern nurseries (fig. 1). Although soil fumigation has reduced losses caused by a number of soil-borne disease pathogens, additional controls are needed for the relatively large number of other hardwood diseases which may be encountered.
