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.

Large scale implementation of microbiological preparations ensures combat not only of the noxious insects but also of pathogen agents which cannot be efficiently combated by other means of biological control. The high efficiency of viral, bacterial and mycotic preparations for combating harmful insects was demonstrated in the main groups of agricultural crops which, being applied in optimal conditions against the corresponding phases. In the report the last performances in elaboration of the biotechnologies for production of the microbiological preparations, and improvement of their application technologies in the system for integrated plant protection of different groups of crops and determination of their place in these systems are much discussed. This report presents the results of state registration of 4 preparations (1 viral, 1 bacterial and 2 fungal) for combating of pest insects and phytopathogen agents.

The agricultural systems used today still face losses caused by phytopathogenic agents, one of them is Venturia inaequalis 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 apple scab. 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% on leaf and over 80 on fruits and can be used as a means of protection, the best to use their mixture.
TESTAREA PREPARATULUI BIOLOGIC SCLEROTSYD® PENTRU PROTECȚIA FLORII SOARELUI DE PUTREGAIUL ALB

For the purpose of sunflower's protection from white mold (pathogen Sclerotinia sclerotiorum), it was tested biologic preparate Sclerotsyd®. The fungicide was used by spraying the working suspension with subsequent incorporation into the soil. Were used three application rates: 1) Sclerotsyd® - 0.5 l/ha, 2) Sclerotsyd® - 1.0 l/ha, 3) Sclerotsyd ® - 2.0 l/ha, control – without applying any products. The purpose of the research is to test the consumption rates and determine the biological effectiveness of the biological product in the control of sunflower’s root and head white mold. As a result, it was established that the most effective use rate of the biopreparation Sclerotsyd® for suppressing the development of sunflower’s mold and white head mold it is recommended the rate of 2.0 l/ha with a biological efficiency of 86.2-87.0%.
