Abstract

When culture blocks of isolates of P.parasitica were incubated on medium containing metalaxyl for 4 to 6 weeks some of the zoospore progenies from A1 isolates were changed to A2 and many of zoospore progenies from A1 and A2 isolates became resistant to metalaxyl. Exposure to metalaxyl also caused many of their zoospore progeny to change colony morphology and growth rate in the absence of metalaxyl indicating that metalaxyl is mutagenic. Zoospore progeny produced by these mutants displayed further segregation in growth rate suggesting that genes affected by metalaxyl are probably located in the cytoplasm
