Item Beneficiile fenomenelor sinergice în protecția plantelor cu aplicarea preparatelor biologice(CEP USM, 2024) Voloșciuc, Leonid; Șcerbacova, Tatiana; Stîngaci, Aurelia; Pînzaru, Boris; Samoilova, Anna; Harciuc, Oleg; Zavtoni, Pantelimon; Lungu, Andrei; Crucean, Ștefan; Curiev, Loredana; Chistol, MarelaThe biological protection of plants through various ecological approaches, the significant diversity of the means used (entomophagous organisms, biological preparations, biologically active substances) and their high biological and economic effectiveness, managed to attract substantial attention and gained a high degree of recognition both among the specialists of highly qualified, as well as agricultural producers, regardless of the form of ownership. The effectiveness of applied biological approaches and methods is also increased against the background of the increasing impact of pesticide media and the need to solve ecological problems. On the path to increasing economic efficiency, we have established the benefits of the simultaneous use of two or more biological means.Item Testarea unui preparat pe bază de Bacillus subtilis pentru protecția grâului de toamnă de patogeni(CEP USM, 2024) Șcerbacova, Tatiana; Lungu, Andrei; Pînzaru, BorisThe results of the testing of the biological fungicide based on the bacteria Bacillus subtilis, strain IAB/BS03 to protect the winter wheat variety Moldova-614 from the complex of pathogens in the conditions of the Republic of Moldova. The research was carried out on the experimental field of the IGFPP of MSU. Two preparation rates of consumption were tested: 2 kg/ha and 3 kg/ha. Used once by the spraying method. As a result, the biological efficiency against Bipolaris sorokiniana was 75,0% and 90,0%, Helminthosporium sativum – 83,3% and 89,7%, respectively, fusarium head blight – 86,0%.Item Aplicarea preparatelor ecologice inofensive contra Podosphaera leucotricha la măr(CEP USM, 2024) Curiev, Loredana; Pînzaru, BorisThe powdery mildew (Podosphaera leucotricha) can induce more than 60-80% damages of apple trees. Harmless organic preparations are proposed for reducing losses caused by the pathogen on apple fruits. The study of the microbiological products biological efficacy in the powdery mildew control were carried out on apple variety Renet Simirenco. The biological efficacy of 10.0 l/ha Rizoplan + Trichodermin-SC in the control of P. leucotricha consisted 77.1% and 80.8% after the first and the second evidence, respectively.Item REOMOLOGAREA PREPARATELOR BIOLOGICE - CALE SIGURĂ DE SOLUȚIONARE A PROBLEMELOR DE PROTECȚIE A PLANTELOR PENTRU AGRICULTURA CONVENȚIONALĂ ȘI ECOLOGICĂ(CEP USM, 2023) Voloșciuc, Leonid; Șcerbacova, Tatiana; Pînzaru, Boris; Stîngaci, Aurelia; Zavtoni, Panteleimon; Lungu, A.; Crucean, ȘtefanLarge 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.Item TESTAREA PREPARATULUI BIOLOGIC SCLEROTSYD® PENTRU PROTECȚIA FLORII SOARELUI DE PUTREGAIUL ALB(CEP USM, 2023) Șcerbacova, Tatiana; Lungu, A.; Pînzaru, Boris; Voloșciuc, LeonidFor 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%.Item ROLUL APLICĂRII BIOPREPARATELOR LA REDUCEREA GRADULUI DE ATAC A RAPĂNULUI LA MĂR(CEP USM, 2023) Pînzaru, Boris; Voloșciuc, Leonid; Șcerbacova, Tatiana; Lungu, A.; Curiev, L.; Vaculin, GalinaThe 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.Item APRECIEREA ACȚIUNII BIOPREPARATELOR ÎN COMBATEREA FĂINĂRII LA CULTURA DE MĂR(CEP USM, 2023) Pînzaru, Boris; Voloșciuc, Leonid; Șcerbacova, Tatiana; Lungu, A.; Curiev, L.; Vaculin, GalinaThe agricultural systems used today still face losses caused by phytopathogenic agents, one of them is Podosphaera leucotricha which can cause 30- 50% losses.
