Those that were not able to…Read more about Bermudagrass Winterkill Again?[Read More]

We recently discovered that the hunting billbug is capable of successfully overwintering in the larval stage as far north as West Lafayette Indiana. This insect is mainly a pest of warm-season turfgrasses such as Bermudagrass and zoysiagrass and has become a perennial problem in parts of the state where these grasses are cultured. Although we’ve…Read more about Hunting Billbug Larvae Overwintering in Indiana[Read More]
