Aprecierea acțiunii biopreparatelor în combaterea făinării la cultura de măr

Abstract

The agricultural systems used today still face losses caused by phytopathogenic agents, one of them is Podosphaera leucotricha which can cause 30-50% losses. The world trend is to develop sustainable agricultural systems and replace chemical pesticides with biological pesticides. This paper presents the testing data of the biopreparation Rizoplan and Trichodermină-SC against powdery mildew of apple. They have been used both separately and in admixture. During the entire vegetation period they provided a high level control of powdery mildew of apple, over 70% and can be used as a means of protection, the best to use their mixture.
