Turfgrass Trends


	Silicon Suppresses Leaf Spotting on Bermudagrass Silicon (Si) is considered a plant-nutrient anomaly because it is presumably not essential for plant growth and development. Soluble silicon, however, has enhanced the growth and development of several plant species including rice, sugar cane, most other cereals and several dicotyledons such as cucumber and water melon. The author present results of a study to determine if Si could enhance host plant resistance to Biploaris cynodontis, the cause of leaf spotting and melting out of bermudagrass in Florida.
