✦ Synopsis

Metalaxyl resistance has been identiÐed in the Phytophthora porri population in the UK. In Ðeld experiments the presence of such resistant strains reduced the level of control of leek white tip given by applications of phenylamide-containing fungicides. The level of control achieved by fungicides with alternative modes of action to the phenylamides was not a †ected.
