Huanglongbing (HLB), associado a Candidatus Liberibacter asiaticus, é a doença de maior impacto econômico na citricultura mundial, comprometendo o metabolismo vegetal, a qualidade dos frutos e a produtividade em escala comercial. Neste estudo, avaliou-se a eficácia do protocolo bioativo Citromics na recuperação fisiológica e no desempenho agronômico de plantas de Citrus sinensis sob condições comerciais no cinturão citrícola do estado de São Paulo, Brasil. Foi conduzido um ensaio de campo controlado e randomizado entre agosto e dezembro de 2025, envolvendo 120 plantas adultas com status de infecção por HLB confirmado por PCR. As plantas foram distribuídas em grupo controle, submetido ao manejo convencional, e grupo tratado, submetido ao protocolo Citromics. Os parâmetros analisados incluíram vigor vegetativo, morfologia foliar, arquitetura da copa, pH foliar, produtividade e valor comercial dos frutos. As plantas tratadas apresentaram melhora consistente em todos os parâmetros avaliados, incluindo redução da expressão visual dos sintomas de HLB, maior densidade de copa, melhor uniformidade foliar e recuperação do desenvolvimento vegetativo. Observou-se aumento significativo do pH foliar, de 5,10 ± 0,31 no grupo controle para 6,20 ± 0,28 no grupo tratado (p < 0,0001), sugerindo restauração fisiológica relevante. Além disso, houve incremento de 22,7% no peso dos frutos por caixa e aumento de 45% no valor comercial, de R$20 para R$29 por caixa, acompanhado de melhor qualidade pós-colheita e menor rejeição comercial. Em conjunto, os resultados indicam que o protocolo Citromics apresenta potencial terapêutico e viabilidade agronômica e econômica para o manejo do HLB, contribuindo para a recuperação funcional das plantas, a preservação da qualidade dos frutos e o avanço de estratégias mais sustentáveis na citricultura contemporânea.

  • Abstract: Huanglongbing (HLB), associated with Candidatus Liberibacter asiaticus, is the most economically damaging disease affecting global citrus production, severely impairing plant metabolism, fruit quality, and orchard productivity. This study evaluated the efficacy of the Citromics bioactive protocol in promoting physiological recovery and agronomic performance in Citrus sinensis trees under commercial orchard conditions in the citrus belt of São Paulo State, Brazil. A randomized controlled field trial was conducted from August to December 2025, involving 120 mature trees with HLB infection status confirmed by PCR. Trees were allocated to a control group under conventional management and a treated group receiving the Citromics protocol. Assessed parameters included vegetative vigor, leaf morphology, canopy architecture, foliar pH, yield, and fruit commercial value. Treated trees showed consistent improvement across all evaluated parameters, including reduced visual HLB symptom expression, greater canopy density, improved foliar uniformity, and recovery of vegetative development. A significant increase in foliar pH was observed, rising from 5.10 ± 0.31 in control trees to 6.20 ± 0.28 in treated trees (p < 0.0001), indicating relevant physiological restoration. In addition, fruit performance improved substantially, with a 22.7% increase in fruit weight per box and a 45% increase in commercial value, from R$20 to R$29 per box, alongside better post-harvest quality and lower commercial rejection rates. Taken together, these findings indicate that the Citromics protocol holds therapeutic potential as well as agronomic and economic viability for HLB management, contributing to functional plant recovery, fruit quality preservation, and the advancement of more sustainable strategies in contemporary citrus production.
