Volatiles produced by the leaves of medicinal plants are increasingly used as a new plant disease management strategy due to their induction of diverse antimicrobial activities, it is highly essential for the development of a new phyto-fumigant product to sustain crop production. The present study attempted to find the active role of associated volatile formulation in the suppression of the growth of under pot culture and field conditions. Damping off disease-causing is a devastating disease that infects the tomato crop from seed sprouting to the seedling stage. To mitigate the damping off incidence, the nature of volatile molecules produced by was completely suppressed during di-trophic interaction with . Molecular docking of volatile compound reported carvone as a ligand recorded with the highest binding energy of - 8.5 kcal/mol against the target protein structure of Application of immobilized vermiculite ball in tomato revealed that pathogenesis-related protein (PR1) (2.69 folds) and jasmonic acid signaling (LOX) (2.65 folds) genes were highly expressed after 48 HPT on tri-trophic interaction of pathogen inoculated tomato plants while the gene WRKY and TLP exhibited a lower level of gene expression. A significant reduction in the severity of damping off incidence was observed due to the exposure of volatiles of in the tomato plant's raised beds with relatively abundant control of This is the first study that attempted to develop the volatile-based formulation and its role in antifungal activities during di-trophic interaction with in tomato crops. The present study concludes that the volatiles produced from leaves immobilized vermiculite ball could be explored for the management of soil-borne pathogens infecting vegetable crops.

药用植物叶片产生的挥发物因其诱导多种抗菌活性而越来越多地被用作一种新的植物病害管理策略，开发一种新的植物熏蒸剂产品对于维持作物产量至关重要。本研究试图在盆栽和田间条件下，探究相关挥发物制剂在抑制[具体微生物名称未给出]生长方面的积极作用。猝倒病是一种毁灭性病害，从种子发芽到幼苗期都会感染番茄作物。为减轻猝倒病的发病率，[具体植物名称未给出]在与[具体微生物名称未给出]的双营养相互作用过程中产生的挥发性分子的性质被完全抑制。对挥发性化合物的分子对接显示，香芹酮作为一种配体，与[具体微生物名称未给出]的靶蛋白结构的结合能最高，为-8.5千卡/摩尔。将[具体植物名称未给出]固定化蛭石球应用于番茄后发现，在接种病原体的番茄植株的三营养相互作用48小时后，病程相关蛋白（PR1）（2.69倍）和茉莉酸信号（LOX）（2.65倍）基因高度表达，而WRKY和TLP基因的表达水平较低。由于在番茄种植床中暴露了[具体植物名称未给出]的挥发物，猝倒病发病率的严重程度显著降低，同时对[具体微生物名称未给出]有相对充分的控制。这是第一项试图开发基于挥发物的制剂及其在番茄作物与[具体微生物名称未给出]的双营养相互作用过程中抗真菌活性作用的研究。本研究得出结论，固定化蛭石球上[具体植物名称未给出]叶片产生的挥发物可用于防治感染蔬菜作物的土传病原体。
