Shane Bogle, Agent for Agriculture and Natural Resources at the UK Extension Office, was in studio Wednesday morning for WPKY’s weekly Extension Program.

Shane started the program out by reminding area corn farmers to be on the lookout for Southern Rust, a disease that affects white corn crops. Shane stated that most of the corn crops have matured faster than the disease but advised farmers to still be on the lookout for signs of the disease as it has been reported in Kentucky.

Shane also mentioned that the West Kentucky Beef Bash will be held on Thursday, September 20th from 8:30AM to 5PM at the Research Center. The event will cover all things beef and forage related including educational lectures and a trade show. A meal will also be provided by the Cattleman’s Association. No registration is required to attend the event. You can contact the Extension Office at 270-365-2787 for more information.

Shane then took a few moments to tell listeners about a major pest that’s affecting evergreen trees and shrubs, bag worms. Bag worms are a caterpillar that make spindle shaped bags that hang from tree limbs and are found more prevalently on evergreen trees. The caterpillars in the larva stage can strip trees of their foliage and can even cause enough damage that trees will die. Shane stated that only males mature into moths while females will stay in their hanging cocoons for their entire life cycle. After a male mates with a female she can lay up to 1,000 eggs. Once the eggs hatch larva emerge and begin feasting on foliage. It only takes nine surviving larva to potentially destroy a small evergreen tree or shrub. Shane revealed that the best way to properly manage bag worms is to physically remove the hanging bags from trees in the late summer before males mature into moths in early September. Shane also mentioned that some insecticide sprays do work, but only when used before new eggs hatch in May and June. He suggested residents use Ortho Insect Killer Tree and Shrub, Captain Jack Dead Bug Brew, or Bayer Multi-Insect Killer next spring to protect trees and shrubs from new hatchlings.
