| Abstract/Contents: | States that "interest has grown in using silicon fertilization of turfgrasses to enhance plant performance and resistance to diseases and abiotic stress." Describes how researchers at the University of Kentucky conducted a study with field-applied silicon fertilizer and evaluated that "as the level of silicon fertilizer was increased, leaf silicon content increased." Discusses how fertilization with silicon enhances resistance of Penncross creeping bentgrass to two major insect pests: foliage-feeding black cutworms and root-feeding masked chafer grubs. Provides the study's findings, reporting that "fertilizing with prilled calcium silicate increased foliar silicon content in [the] creeping bentgrass field plots by 36% to 40%, and sodium silicate soil drenches gave 2.5 to five-fold increases in the greenhouse." Concludes that "although silicon doubtless contributes to the general structural defense of turfgrass by lowering food quality for insects and other herbivores, [the] data [suggests] that augmenting silicon is unlikely to enhance resistance of creeping bentgrass to two of its major insect pests." |
