    FOSFITOS DE POTASSIO PARA O CONTROLE DO MILDIO DA ROSEIRA (PERONOSPORA SPARSA BERK.)

    Abstract

    Downy mildew is one of the most important diseases in rose crop in the world. The control is done with continuous applications of fungicides, which may eventually favor the emergence of resistant strains. In the search for environmentally compatible alternatives to control downy mildew, two different potassium phosphite formulations were tested on downy mildew, and the effects of these products on the length, diameter and total chlorophyll concentration of roses were evaluated. The roses sprayed with both formulations showed lower levels of incidence and severity. The different phosphite formulations increased the stem length, diameter and total chlorophyll concentration of roses compared to the other treatments.
