![]() ![]() Stems turn straw colored and die in a scattered fashion. Large larvae will burrow out and feed on the crown. Young larvae burrow into grass stems, feeding and tunneling. BillbugsĮggs are laid between leaf sheaths and hatch in 4-5 days. Irrigate to moisten soil and thatch then again immediately after application, before spray droplets dry. Biorational products: entomopathogenic nematodes (Steinernema carpocapsae)–apply in early morning or late afternoon to avoid heat or direct sunlight. Contact insecticides: acephate (ORTHENE, Group 1B), chlorpyrifos (DURSBAN, Group 1B), cyfluthrin (TEMPO) ,deltamethrin (DELTAGARD, Group 3A), trichlorfon (DYLOX Group 1B), carbaryl (SEVIN, Group 1B ), acelepryn (Group 28). Apply in the afternoon and avoid irrigating over night. ![]() Avoid mowing for at least 1-3 days after application of insecticides. Bt (Bacillus thuringiensis) may provide some control of small larvae (do not irrigate). Spinosad (CONSERVE, IRAC Group 5) is an effective chemical control. Large larvae will eat all leaf material down to crown region. Scrap underside of leaf blades, leaving a clear upper skeletal epidermal layer chew leaf margins, leaving a tattered look. Only 23-28 days required to complete a generation during mid-summer. Older larvae will pupate in the soil, and new moths will emerge in 9-20 days depending on temperature. Larvae mature in about 12 days during summer and 4 weeks during cool weather. Eggs hatch in 7-10 days during cool weather and in 2-3 days during hot weather. Fall army wormįemales lay egg clusters on grass blades, other green plants, twigs, fences, sides of buildings, or any light colored object near turf. Infestations of the following insects have been documented in seashore paspalum. Read and follow all restrictions on the labels, as there have been changes made recently to neonicotinyl use instructions. If there are flowering weeds, such as clover, in the turf, the blossoms should be mowed before application of this class of insecticide. ![]() The neonicotinyl insecticides (IRAC group 4A) have systemic activity and can move to pollen and nectar if applied to plants in bloom. Use extreme care when applying insecticides to flowering plants, including turfgrasses. Many insecticides are extremely toxic to bees, and others can affect colony health with repeated exposure. Managed landscapes often contain flowering plants and can be important foraging sites for bees and other pollinators. Once the insects are controlled, the grass will grow back. Fortunately, there are a number of products that can be used for this. If you detect an insect infestation you will need to spray your seashore paspalum with an insecticide. There are several types of insects that seem to like paspalum in particular, and left untreated, can cause significant damage. ![]()
