Selected for its extraordinary speed of foliar colonization and its ability to produce a powerful antifungal metabolic arsenal, this strain forms the scientific backbone of the technical efficacy of TRIBUM, the next-generation foliar biofungicide within the PLUVIGEA\u00ae line.<br>Its field performance, formulation stability, and biotechnological precision have positioned it as a benchmark in Integrated Pest Management (IPM) programs and as a key tool for high-value crops across Europe.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>A strain designed to colonize first and protect for longer<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike other <em>Bacillus<\/em> strains more closely associated with root activity, AH2 was specifically selected for its ability to colonize aerial plant tissues: leaves, flowers, fruits, and peduncles.<br>Its unique biological behavior is based on three essential attributes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Extremely rapid establishment<\/strong>, capable of occupying the foliar surface within just a few hours.<\/li>\n\n\n\n<li><strong>Immediate production of antifungal metabolites<\/strong>, including lipopeptides, hydrolytic enzymes, and siderophores.<\/li>\n\n\n\n<li><strong>High persistence<\/strong>, maintaining activity even under variable humidity and temperature conditions.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This foliar affinity makes AH2 an optimal strain for managing pathogens such as <em>Botrytis cinerea<\/em>, <em>Monilinia<\/em> spp., and <em>Stemphylium<\/em> spp., which are responsible for significant losses in horticultural and fruit crops.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>A complete and scientifically validated mode of action<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The performance of <em>B. amyloliquefaciens<\/em> AH2 is explained by a triple, complementary, and synergistic mode of action:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>1. Competition for space and nutrients<\/strong><br>AH2 rapidly colonizes the plant surface and forms a dense biofilm that restricts pathogen access to the resources required for germination.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2. Production of antifungal metabolites<\/strong><br>The strain generates multiple active compounds:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lipopeptides (iturin, fengycin, surfactin)<\/li>\n\n\n\n<li>Lytic enzymes (chitinases, proteases, and glucanases)<\/li>\n\n\n\n<li>Siderophores that sequester iron, halting pathogen development<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This molecular arsenal directly degrades fungal membranes and structures, effectively blocking disease progression.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>3. Activation of plant responses<\/strong><br>AH2 stimulates key physiological pathways, enhancing the crop\u2019s ability to respond to fungal pressure without forcing unnecessary processes or generating residues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This integrated approach ensures prolonged protection for more than 21 days and significantly reduces the risk of resistance development.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Authorized crops and uses in Spain<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The commercial formulation based on this strain\u2014PLUVIGEA\u00ae TRIBUM\u2014holds Spanish registration ES-01534 and is authorized for use in a wide range of crops:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Authorized crops<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bulb crops and vegetables<\/li>\n\n\n\n<li>Strawberry<\/li>\n\n\n\n<li>Stone fruit trees<\/li>\n\n\n\n<li>Lettuce and similar leafy vegetables<\/li>\n\n\n\n<li>Grapevine<\/li>\n\n\n\n<li>Blueberry, edible-skin cucurbits, raspberry, strawberry, solanaceous crops (except potato)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Target pathogens<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><em>Botrytis cinerea<\/em><\/li>\n\n\n\n<li><em>Monilinia<\/em> spp.<\/li>\n\n\n\n<li><em>Stemphylium<\/em> spp.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>AH2, a new benchmark in European biocontrol<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In conclusion, <em>Bacillus amyloliquefaciens<\/em> AH2 (CECT-7221) represents a technological leap forward in the biological management of plant diseases.<br>Its exceptional colonization speed, metabolic stability, and proven efficacy position it as one of the most complete strains for regenerative, sustainable, and residue-free agricultural systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Through PLUVIGEA\u00ae TRIBUM, Veganic places this exclusive strain at the service of the farmer, driving a faster, more precise form of bioprotection fully aligned with regenerative agriculture.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The exclusive strain behind the exceptional performance of PLUVIGEA\u00ae TRIBUM Bacillus amyloliquefaciens AH2 (CECT-7221) is one of the most advanced microbial strains in modern bioprotection.
