In turf grass, sprinkling soapy water(e.g., 1-2 fl. Larvae are typically about an inch long, have a small black head and vary in color from nearly black to grey brown or multicolored in the case of variegated cutworms.

They are a little hard to see, but there are about 50 birds on bentgrass area below at the research station. Primarily Black cutworm (Agrotis ipsilon) Variegated cutworm (Peridroma saucia). He has covered the green industry for more than 10 years. The black cutworm (Agrotis ipsilon) is the most commonly reported and the bronzed cutworm (Nephelodes minians), variegated cutworm (Peridroma saucia), and bristly cutworm Lacinipolia renigera) occasionally cause problems in turf.

Sign in Larvae emerge from underground burrows in the soil at night to chew on grass leaves and stems. Pupae are … For us at the research station, it is normally about field day time that they become a problem. Shortly after application, black cutworm larvae and other turf infesting caterpillars become irritated by the soap flush and rise to the surface. The larval stage appears as a smooth bodied, dark coloured caterpillar with longitudinal lines and brown to black spots on back and sides. It does the most injury to turfgrass in the larval stage as a caterpillar before maturing into an adult moth. Numerous convex skin granules give the larvae an overall shiny and "greasy" appearance. Black cutworm (BCW) is the most destructive of all cutworm species that attack turfgrasses.
