Abstract
SUMMARY One out of 42 Spanish isolates of P.halstedii ascribed to races 1, 2, 4, 6, 7 or 10 showed consistent tolerance to metalaxyl when seeds of sunflower ‘Peredovik’, treated with this fungicide at 2 g.a.i./kg, were inoculated by wholeseedling dipping. When this metalaxyl-tolerant isolate of P.halstedii was inoculated to sunflower seedlings by this method, the fungicide seemed to affect neither zoosporangia nor zoospores. In contrast, the incidence of seedlings with high sporulation on cotyledons after 10-12-day incubation was significantly decreased with increasing dosages of metalaxyl applied to the seeds of sunflower. EC 50 of this tolerant isolate of P.halstedii was estimated at 3.5-5 g.a.i./ kg.
