The resistance of loblolly and slash pines to fusiform rust (Cronartium fusiforme) was studied. There was a marked difference in rust resistance between the five seed sources of loblolly pine planted on the SPR. After several growing seasons there was little infection on Texas and Arkansas sources and only light infection on Louisiana and Maryland sources compared to susceptible controls. Greenhouse tests indicated the Maryland source was most resistant. Trees from fusiform resistant and susceptible seed sources were treated with 300 or 600 pounds of N per acre via a municipal sludge. The 300-pound application produced the most growth. Level of sludge application had no influence on fusiform infection. There was found to be no direct correlation between levels of rust resistance in 20 loblolly pine families and their visible injury following treatment with SO/sub 2/ and SO/sub 3/.
