Specific recommendations for home lawn and commercial control can be found in the North Carolina Agricultural Chemicals Manual. Treating a 20-30 foot buffer zone around greens and tees will reduce migration from outlying areas. Use liquid formulations, apply as late in the day as possible, and avoid irrigating for at least 24 hours. Apply chemicals in the evening for optimal night time contact. Precede chemical treatments with mowing 24 hours prior to treatment. When monitoring for cutworms (see Monitoring for Turfgrass Insects), a general threshold of 2-6 larvae per square yard may indicate a need for an insecticide application, although this threshold could change depending on site. Collection and removal of clippings from a recently-mowed area may be helpful in removing eggs from the turf stand. This may be used in mixed turf or in border areas. Kentucky bluegrass is a non-preferred host, for black cutworm, compared to creeping bentgrass and perennial rye and may reduce infestation.
