A Method for Screening Candidate Nematicides Against the Pacific Shoot-Gall Nematode, Anguina Pacificae

A growth chamber bioassay was developed for testing the efficacy of potential nematicides against the Pacific shoot-gall nematode, Anguina pacificae. Twenty nine products were assayed, eight of which showed some degree of control. Agroneem Plus, Avid, Cleary 3336 Plus, Levimisole, Neemix +Trilogy, Nemacur, Aldicarb and Vydate penetrated young galls on Poa annua, 10 days after inoculation, and interrupted the nematode's life cycle, either by preventing the development of second generation infective juveniles or by causing the formation of "empty" galls that contained no nematodes. A modification of the assay was used to demonstrate the acropetal systemic activity of Cleary 3336 Plus.
