FUNGICIDES AND THE NUTRIENT FILM TECHNIQUE

Etridiazole, furalaxyl, metalaxyl and copper oxinate were tested for their effects on the growth of species of Phytophthora and Pythium.
These effects differed considerably, some species being more tolerant than others.
Even at low concentrations the first three fungicides prevented zoospore formation.
The formulations used were: etridiazole as Aaterra W.P., copper oxinate as Quinolate 400 obtained from Duphar Midox, Smarden, Kent.
Furalaxyl and metalaxyl as Fongarid and Ridomil, respectively, obtained from Ciba Geigy, Cambridge.

Mixtures of etridiazole and copper oxinate were more effective than either alone in preventing growth of most species tested.
