JASPER, Mônica; PRIA, Maristella Dalla  and  SILVA, Andressa Andrade e. Uso do leite de vaca in natura no controle de oídio na cultura da gérbera. Summa phytopathol. [online]. 2009, vol.35, n.4, pp.322-324. ISSN 0100-5405.

Gerbera (Gerbera jamesonii) is one of the most popular ornamental plants in the world, used as cut or vase flower. The experiment aimed to evaluate the effect of milk in natura to control powdery mildew (Erysiphe cichoracearum) on gerbera. The treatments tested were: two concentrations of cow's milk in natura (8 and 16%), with and without adjuvant (vegetal oil), three fungicides (fenarimol -6 g a.i.100 L-1 H2O, chlorothalonil -150 g a.i.100 L-1 H2O and azoxystrobin + mineral oil - 10 g a.i.100 L-1 H2O) and control treatment. The area under the disease progress curve (AUDPC) was calculated for each plot based on disease severity. Milk in natura applied with adjuvant controlled the disease and did not allow the infection and development of pathogen. The addition of adjuvant improves the efficiency of milk in natura, but it requires subsequent washing of plants with H2O + detergent. The fungicide fenarimol promoted the best control and also the best gerbera visual aspect. The fungicide azoxystrobin + mineral oil and the chlorothalonil were phytotoxic to gerbera plants, affecting the aspect of leaves and flowers.

Keywords : Gerbera jamesonii; fungicidas; controle alternativo; Erysiphe cichoracearum.
