"Shellshock" Developing methods of using chitin to reduce potato cyst nematode populations

Potato cyst nematodes (PCN) (Globodera spp.) are serious pests, occupying c.48% of the potato growing area in England and Wales (AHDB, 2019) and 13.2% of production land in Scotland (Pickup et al., 2019). Chitin is one of various alternative crop protection options being investigated to reduce PCN, and is present in several industry by-products including shellfish waste composed of crustaceans, such as langoustines, crabs and lobsters, spent mushroom compost (SMC) and the frass and pupal cases associated with black soldier fly (BSF) production. This project seeks to evaluate the potential of chitinous amendments in the suppression of PCN.
