Stem rot of groundnut ( L.) caused by is the main threat to groundnut production, causing significant economic losses. The present study aims to provide an overview of the potentiality of (Tv), (Th), (Pf), and (Bs), applied either individually or in mixed combination, against (isolate SrBKN). The treatment with and resulted in the highest mycelial growth inhibition (79.61, 83.51, and 86.77%), followed by and (75.74, 79.63, and 83.14%). Under in vitro conditions, the combination of bio-agents at 5% culture filtrate proved to be superior against the test pathogen. Seed treatment and soil application of and at 10 (5 + 5) g kg + 10 (5 + 5) kg ha, followed by seed treatment and soil application of and at 10 (5 + 5) g kg + 10 (5 + 5) kg ha, resulted in the lowest disease incidence (7.40 and 8.0%), highest disease control (69.37 and 66.88%), maximum dry weight (151 and 147 g plant), highest increase in dry weight (75.58 and 70.93), highest pod yield (2665 and 2498 kg ha), and highest increase in pod yield (96.38 and 84.08%) under in vivo conditions. We present an effective bio-control-based management module from the lab to the field for the successful control of groundnut stem rot caused by . Based on the results, it is concluded that the dual formulation of and , followed by and , were the most effective BCAs in suppressing the . Therefore, an integrated disease management module with these BCAs needs to be developed and validated with a farmers' participatory mode under field conditions.
由[病原体名称未给出]引起的花生茎腐病是花生生产的主要威胁，会造成重大经济损失。本研究旨在概述单独或混合施用[木霉菌（Tv）、哈茨木霉（Th）、拟青霉（Pf）和芽孢杆菌（Bs）未给出具体中文名称]对[病原菌（分离株SrBKN）未给出具体中文名称]的防治潜力。用[木霉菌（Tv）、哈茨木霉（Th）、拟青霉（Pf）和芽孢杆菌（Bs）未给出具体中文名称]处理导致菌丝生长抑制率最高（分别为79.61%、83.51%和86.77%），其次是[另外两种菌未给出具体中文名称]（分别为75.74%、79.63%和83.14%）。在体外条件下，5%培养滤液的生物制剂组合对测试病原菌表现出更好的防治效果。以10（5 + 5）克/千克 + 10（5 + 5）千克/公顷的用量对种子进行处理并施用于土壤中的[木霉菌（Tv）、哈茨木霉（Th）、拟青霉（Pf）和芽孢杆菌（Bs）未给出具体中文名称]，以及随后以10（5 + 5）克/千克 + 10（5 + 5）千克/公顷的用量对种子进行处理并施用于土壤中的[另外两种菌未给出具体中文名称]，在体内条件下导致发病率最低（分别为7.40%和8.0%）、病害防治效果最高（分别为69.37%和66.88%）、最大干重（分别为151克/株和147克/株）、干重增加最多（分别为75.58和70.93）、荚果产量最高（分别为2665千克/公顷和2498千克/公顷）以及荚果产量增加最多（分别为96.38%和84.08%）。我们提出了一个从实验室到田间基于生物防治的有效管理模块，用于成功防治由[病原菌未给出具体中文名称]引起的花生茎腐病。基于这些结果，可以得出结论，[木霉菌（Tv）、哈茨木霉（Th）、拟青霉（Pf）和芽孢杆菌（Bs）未给出具体中文名称]的双重配方，其次是[另外两种菌未给出具体中文名称]，是抑制[病原菌未给出具体中文名称]最有效的生物防治剂。因此，需要开发一个包含这些生物防治剂的综合病害管理模块，并在田间条件下以农民参与的方式进行验证。
