Rezumat

Downy mildew in sunflower has a major impact on seed yield, in years when pathogen Plasmopara hastedii has developed. Climatic conditions from year 2018, has no influence in development of this pathogen because in months April and May was registered high temperature and no precipitations, but in year 2019 situation is changed. In early sowing, in field condition, in begging of April of year 2019, was no infection on sunflower genotypes. In late sowing, in field condition, in middle of May of year 2019, was a big infection with downy mildew in sunflower. For this reason, we must obtain new genotypes of sunflower with genetic resistance at new races of pathogen Plasmopara halstedii.
