Biological control of cucumber powdery mildew with Tilletiopsis minor under greenhouse conditions

  • T. Hijwegen


In growth cabinet and greenhouse experiments the efficacy ofTilletiopsis minor in controlling cucumber powdery mildew decreased as humidity was lowered. This effect could be counteracted by formulation of the mycoparasite with lipophilic substances, like Hora Oleo 11E and lipids from milk. These formulations, without the mycoparasite, were also found to be deleterious to powdery mildew development. In the long run, however, formulations withT. minor gave better biological control of cucumber powdery mildew than formulations alone.
