    APLICAREA BACTERIILOR ENTOMOPATOGENE BACILLUS THURINGIENSIS, VAR.THURINGIENSIS ȘI FP-09 CONTRA LEPTINOTARSA DECEMLINEATA LA CULTURA CARTOFULUI
    (CEP USM, 2024) Zavtoni, Pantelimon; Voloşciuc, Leonid; Stîngaci, Aurelia
    Data were obtained on the application of the entomopathogenic bacterium Bacillus thuringiensis in synergy with FP-09 for the control of Colorado potato beetle on the potato variety Marabel. The action of entomopathogenic bacteria in combination with FP-09 was determined in the control of Colorado potato beetle larvae stages I and III of the second generation Colorado potato beetle (Leptinotarsa decemlineata) under field conditions on potato crop of the variety «Marabel», where the average biological efficacy of Bacillus thuringiensis 108+ FP-09 was 75.9%. The first and third instar larvae control action was determined with FP-09, where the biological efficacy in controlling larvae of Leptinotarsa decemlineata was on average 37.8%.

    Bacillus thuringiensis var. thuringiensis in combaterea larvelor gândacului din Colorado
    (CEP USM, 2024) Zavtoni, Pantelimon; Goncharuk, Violeta
    The action of entomopathogenic bacteria in combination with FP-09 was determined in the fight against the larvae of the first and third instars of the Colorado beetle (Leptinotarsa decemlineata) in the second generation in field conditions on the "Marabel" variety potato crop, where the biological effectiveness of the variant Bacillus thuringiensis 108 + FP-09 constituted 76.6%. And the biological effectiveness of the entomopathogenic suspension of Bacillus thuringiensis in the control of first-third instar larvae in the variant with FP-09 in combating Leptinotarsa decemlineata larvae was 6.8%. On the potato lots where a solution of the entomopathogenic bacteria Bacillus thuringiensis, FP-09 was used, several entomophages were observed.

    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, Marela
    The 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.
