Anguina agrostis is a seed gall-forming nematode primarily associated with Agrostis capillaris (bentgrass). While earlier reports suggested a broader host range, current consensus limits its natural host to A. capillaris. The species was previously referred to as A. agrostis sensu lato, but taxonomic revisions have clarified its identity. It spreads through contaminated seed and produces long-lasting galls that can persist in soil for up to a decade, posing a significant risk to seed quality.
Poaceae family species, primarily in bentgrass, fescue, and ryegrass.

Visual inspection
ANGUAG-10
The seed is soaked in 500 ml of water for 48 h, followed by blending, sieving, and screening 20 ml of flowthrough for SGNs under a dissecting microscope. This process is customary for detection in seed shipments but has not been standardized.
Chemical, Cultural
CABI CPC, ANGUAG-7
Cultural methods are being researched such as crop rotation, fallowing, and ploughing. Nematicides have shown effective in infected fields. Hot water at 52 °C for 15 min, followed by a 2-hour water soak.
