Sportnem-H contains insect pathogenic nematodes Heterorhabditis bacteriophora, which target chafer grubs in turf. Applied as a drench, the nematodes move through the moist soil to find a chafer grub and release symbiotic bacteria that feed on the host. The product also controls bibionid fly.
Sportnem-T contains Steinernema carpocapsae. Effective against a number of turf pests but especially the larvae of crane flies, these insect pathogenic nematodes seek out the larvae and penetrate them via the epidermis or natural orifices such as the mouth, anus and breathing holes. The nematodes feed on the contents of the grub, excreting specific bacteria from their digestive tracts as they do so.
As soil temperatures drop, crane fly larvae penetrate deeper into the soil and hibernate. Nemaflo is a carrier to aid the movement of insect-parasitic or entomopathogenic nematodes into the soil profile to the target pest. It is designed to partner Sportnem-H and Sportnem-T as well as any other soil-applied beneficial nematode product.
