Abstract The effects of fusiform rust on product yields from loblolly pine plantations are modeled in four stages: The additional mortality caused by the disease; additional infection observable after age five (the age from which increased mortality is estimated); a probability density function to describe gall heights on infected stems; and a merchandising routine based on specific milling practice assumptions and merchandising strategies. These processes are then incorporated into the North Carolina State University Managed Loblolly Pine Plantation Growth and Yield Simulator, and the effect of various levels of rust incidence on product yields in unthinned stands simulated. Yield of solid product decreased sharply across plantations with increasing infection. Pulp yields increased because of infected stem components that could only be utilized for this product. South J. Appl. For. 12(4):226-231
