| Abstract: | Simulated acid rains of pH 5.6, 4.0, 3.5, 3.0, 2.5, or 2.0 were applied to leaves of broadleaf tobacco twice per week for 1, 2, 3, 4, or 5 weeks. Only those plants receiving rain of pH 2.0 were injured and, among those, the plants receiving fewer applications had less severe injury. Foliar symptoms resembled weather fleck (O3 injury) at first, but become distinguishable from them with time. |
