Popis:	(...) During a 2-yr field study in a 70-yr-old citrus orchard, the soil population of P. parasitica was significantly lower under drip irrigation than under furrow irrigation. (...) The abundance of citrus roots under furrow irrigation increased with distance from the furrow center. (...) Distribution of P. parasitica propagules correlated directly with the distribution of citrus feeder roots. In both greenhouse and lathhouse, Phytophthora root rot of citrus seedlings was most severe where seedlings were watered by drip irrigation or kept constantly moist by furrow irrigation. Seedlings that received water by furrow irrigation that allowed the soil to dry sufficiently between irrigations were able to produce more feeder roots than seedlings grown under drip irrigation.
