is a devastating soil borne pathogen causing collar rot in chickpea, leading to significant crop yield losses. Sustainable diseases management strategies are required to reduce dependence on chemical fungicides and mitigate environmental hazards risks. Biochar, a carbon-rich soil amendment, improves soil health and enhances soil microbial activity, aiding in soil borne disease suppression. , known for its bioactive compounds, exhibits antifungal properties that can prevent . Additionally, , is effective biocontrol agent, promotes plant growth and disease suppression; thus, making the integrated use of these components a promising approach for controlling of in chickpea cultivation.
Chickpea plants were treated with 3% Rice husk biochar (RHB), 450 ppm extract, and to assess their effectiveness against . The study analyzed biochar properties (C, H, N, P, ash content, cation exchange capacity and surface area) and treatment impacts on spore counts (CFU/mL), plant growth (root mass and shoot length), soil health (microbial population), disease incidence (%), and phenolic content in field conditions.
Key findings indicated that 3% RHB (52.3% carbon, pH 8.2) with 450 ppm cassia extract significantly enhanced growth and soil fertility. It achieved a spore count of 34 × 10⁵ CFU/mL, lowering disease incidence from 64 to 35%. This combination also resulted in an increased shoot length of 45.7 cm, root mass of 4.73 g/plant, and phenolic content of 0.49 µg GAE g.
The current study revealed that the biochar-cassia- combination enhances plant defense, manages soil-borne pathogens, and boosts crop productivity due to its phenolic content. This integrative approach offers a sustainable, eco-friendly strategy for managing soil-borne pathogens and improving crop productivity. Future research should investigate the underlying molecular mechanisms and expand its application to other crops and pathogens.
是一种极具破坏性的土传病原体，可导致鹰嘴豆根腐病，造成作物产量大幅损失。需要可持续的病害管理策略来减少对化学杀菌剂的依赖，并降低环境危害风险。生物炭是一种富含碳的土壤改良剂，可改善土壤健康状况并增强土壤微生物活性，有助于抑制土传病害。以其生物活性化合物而闻名，具有抗真菌特性，可预防。此外，是一种有效的生物防治剂，可促进植物生长并抑制病害；因此，将这些成分综合使用是鹰嘴豆种植中控制的一种有前景的方法。
用3%稻壳生物炭（RHB）、450 ppm提取物和处理鹰嘴豆植株，以评估它们对的防治效果。该研究分析了生物炭特性（碳、氢、氮、磷、灰分含量、阳离子交换容量和表面积）以及处理对孢子计数（CFU/mL）、植物生长（根质量和茎长）、土壤健康（微生物种群）、发病率（%）和田间条件下酚类含量的影响。
主要研究结果表明，3% RHB（含52.3%碳，pH值8.2）与450 ppm决明子提取物显著促进了生长和土壤肥力。其孢子计数达到34×10⁵ CFU/mL，发病率从64%降至35%。这种组合还使茎长增加了45.7厘米，根质量达到4.73克/株，酚类含量为0.49微克GAE/克。
当前研究表明，生物炭-决明子-组合因其酚类含量可增强植物防御能力、管理土传病原体并提高作物生产力。这种综合方法为管理土传病原体和提高作物生产力提供了一种可持续、环保的策略。未来的研究应探究其潜在的分子机制，并将其应用扩展到其他作物和病原体上。
