BIOTA LLC successfully completed treatments against the coniferous tussock (Calliteara abietis) burrowing moth and the Siberian silkworm using our biological insecticide, "DEFILIGNUM, SK" in several forestry areas in the Republic of Buryatia, as well as in forest areas in the Novosibirsk and Tyumen Regions. Since its market launch, "Defilignum, SK" has consistently demonstrated the highest level of effectiveness among biological forest protection products. This year, the effectiveness of "Defilignum, SK" also exceeded 95%. More information about the progress of the work can be found in the report on the Rossiya 1 television channel. https://vk.com/wall-10231784_141047
