Chickpea wilt caused by Fusarium oxysporum f. sp. ciceris (FOC) is one of the most prevalent and damaging diseases in chickpea-growing areas. To manage FOC in an environmentally friendly and sustainable manner, the current studies were carried out in 2023 and 2024, and emulsion-based bioformulations of two potential Trichoderma isolates, T. harzianum AMUTH-1 and T. viride AMUTV-1 were prepared and tested under field conditions. For comparison, Pseudomonas fluorescens AMUPF-1, Grow-Power™ (commercial bioagent) and fungicide (carbendazim) were used as benchmarks. Field studies have shown that chickpea variety RVG-202 was highly susceptible to FOC and developed severe wilt at the vegetative stage. However, application of the emulsion-based bioformulation of T. harzianum significantly reduced the wilt severity (55%) and enhanced the plant growth and yield of chickpea by 23-33% and 31%, respectively. The effect of this emulsion formulation was also at par with fungicide, carbendazim and commercial bioagent, Grow-Power™. Hence, T. harzianum emulsion bioformulation may be considered as an alternative control measure for multi-pathogenic diseases of chickpea plants. This outcome could also be used to devise a suitable integrated management module to safeguard chickpea plants from the FOC.
由尖孢镰刀菌鹰嘴豆专化型（FOC）引起的鹰嘴豆枯萎病是鹰嘴豆种植区最普遍且危害最大的病害之一。为了以环境友好和可持续的方式管理FOC，于2023年和2024年开展了当前研究，制备了两种潜在木霉菌株哈茨木霉AMUTH-1和绿色木霉AMUTV-1的乳液型生物制剂，并在田间条件下进行了测试。作为对照，荧光假单胞菌AMUPF-1、Grow-Power™（商业生物制剂）和杀菌剂（多菌灵）用作基准。田间研究表明，鹰嘴豆品种RVG-202对FOC高度敏感，在营养生长阶段出现严重枯萎。然而，施用哈茨木霉的乳液型生物制剂显著降低了枯萎严重程度（55%），并分别使鹰嘴豆的植株生长和产量提高了23%-33%和31%。这种乳液制剂的效果也与杀菌剂多菌灵和商业生物制剂Grow-Power™相当。因此，哈茨木霉乳液生物制剂可被视为鹰嘴豆植株多病原病害的一种替代防治措施。这一结果也可用于设计一个合适的综合管理模块，以保护鹰嘴豆植株免受FOC侵害。
