First detected in Michigan in 1962 the Cereal Leaf Beetle (Oulema melanopus) can cause significant yield and quality reduction in small grains. The larva (brown-yellow with a slimy mass of fecal material on their backs, think slugs) is the most damaging stage. It is important to note that spring grains are favored over winter grains as a food source due too lush new growth at time of egg laying. It is extremely important to monitor for adults, eggs and early larval populations to determine treatment. Most treatments can be piggy backed with flag leaf fungicide applications.
