If you have wheat planted it is time to start scouting for cereal leaf beetle larva. Penn State Extension Entomologist, John Tooker is advising growers to scout for cereal leaf beetle. During 2010 pressure from the cereal leaf beetle was heavy and many fields experienced yield loss. There is potential for cereal leaf beetle populations to be heavy. If populations go unnoticed the flag leaf could be damaged resulting in crop loss or yield loss. The larvae of cereal leaf beetle are recognized by many growers as a shiny black "blob" on the leaf. You know you have walked through a heavily infested field when you have black spots all over your pants.
