| Abstract/Contents: | "Soluble silicon (Si) has enhanced the growth and development of several plant species including rice, sugarcane, and most other cereals [cereal] crops. Researchers at the University of Florida conducted experiments to determine if bermudagrass can accumulate silicon and if silicon could enhance host plant resistance to Bipolaris cynodontis, the causal organism of leaf spotting and melting out of bermudagrass. They found: There was a significant linear increase in silicon that accumulated in the leaves of bermudagrass as the rate of calcium silicate amended to the soil increased. Silicon also was very effective in suppressing leaf spot development on bermudagrass caused by B. cynodontis. Final % leaf spot severity was reduced by 38.9% compared to untreated controls. These results suggest that when soils low or limiting in plant available silicon are amended with a soluble source of silicon, the resistance of bermudagrass against leaf spotting caused by B. cynodontis can be enhanced. This also suggests that fungicides might be better managed if used in combination with silicon for controlling diseases in turf." |
