| Abstract/Contents: | "Equal numbers of Pennlawn rescue (Festuca rubra) seedlings growing in 7.6-cm pots containing sand were watered routinely and infested 2 wk after planting with 2,000 larvae and adults of Pratylenchus penetrans. Starting one month after planting, seedlings were watered three times a week with equal volumes of water adjusted with sulfuric acid to pH 1.8 and 2.6, distilled water at pH 5.6, or tap water at 8.7. Plants were harvested, nematodes recovered from roots, and roots and grass dry weights measured 3, 5, and 8 wk after initial pH treatments. Greatest nematode populations, based on per gram of tissue dry weight, occurred in grass treated with water adjusted to pH 2.6. Lowest populations occurred where plants were treated with water at pH 1.8. Nematode populations were intermediate in grass watered at pH 5.6 and 8.7. Detrimental effects on grass occurred mainly at pH of 1.8; 35% of the leaf area was necrotic and dry matter was considerably less at this value than at others. Dry matter produced was comparable at pH 2.6, 5.6, and 8.7. Data indicate that acidic rainfall, or natural watering at extreme low pH, may influence populations of lesion nematodes on fescue." |
