Description: Slash pine was grown in central Louisiana under four levels of culture with or without repeated sprayings of the systematic fungicide triadimefon for protection against fusiform rust. The eight treatment combinations were: (1)no fungicide, weed control, or fertilizer; (2)weeded; (3)weeded, applied inorganic fertilizer, and bedded before planting; (4)weeded, bedded, and applied inorganic fertilizer in the sixth growing season (delayed fertilization); (5)applied fungicide but no weed control or fertilizer; (6)applied fungicide and weeded; (7)applied fungicide plus treatment 3; and (8)applied fungicide plus treatment 4. Fungicide applications greatly reduced fusiform rust impact in 10-yr-old slash pine stands. Fungicide treatments resulted in higher survival, fewer trees with stem galls, fewer trees with galls encircling 76%-100% of the stem circumference, greater total volume/ac, and less volume/ac among infected trees. The fungicide-treated trees had fewer stem galls below 5ft of tree height compared with untreated trees, indicating that the fungicide treatment protected planted seedlings throught several growing seasons. Weed control increased fusiform rust incidence. The fungicide-treated plots recieving delayed fertilization yeilded the most volume (3018 ft3/ac) after 10 growing seasons because of high stocking and accelerated growth following fertilization.
