Cashew wilt, caused by the soil borne fungus Fusarium oxysporum, is a fast spreading disease that is currently threatening the cashew industry in Tanzania, which is a major source of income for cashew growers and the country. The disease causes the death of the trees within a few weeks of infection. Cashew seedlings treated with either Bacillus strains or T. asperellum biofungicides developed significantly (p < 0.05) lower disease severity levels (0–7.54%) compared to untreated cashew seedlings (0–27.27%). No disease symptoms were observed on cashew seedlings treated with Bacillus velezensis strain 13/A + 3 at 0.5, 1.0, and 2.0 mls of a spore suspension at 1 × 10⁴, 2 × 10⁴ and 3 × 10⁴ ml of spore suspension. Under field conditions, cashew trees treated with biofungicides developed significantly (p < 0.001) lower disease severity of 0–11.49% and 0–12.98% in both seasons (2019/2020 and 2020/2021 respectively) compared to the untreated controls (60.05% and 59.71% respectively). Results from this study indicate the potential of the tested biological control agents in the management of cashew wilt disease caused by F. oxysporum. However, further studies are recommended to determine the shelf life and effectiveness of the biological control agents particularly in a field setting, as well as the efficacy of various formulations.

由土壤传播的真菌尖孢镰刀菌引起的腰果枯萎病是一种快速传播的疾病，目前威胁着坦桑尼亚的腰果产业，而腰果产业是腰果种植者和该国的主要收入来源。这种疾病会在感染后的几周内导致树木死亡。与未经处理的腰果幼苗 (0–27.27%) 相比，用芽孢杆菌菌株或曲霉菌 ( T. asperellum ) 生物杀菌剂处理的腰果幼苗的疾病严重程度水平 (0–7.54%) 显着降低 (p < 0.05)。在用0.5、1.0和 2.0 毫升 1 × 10 ⁴、2 × 10 ⁴的孢子悬浮液处理的腰果幼苗上未观察到任何疾病症状。和 3 × 10 ⁴  ml 孢子悬浮液。在田间条件下，与未经处理的对照（60.05%）相比，在两个季节（分别为 2019/2020 年和 2020/2021 年），用生物杀菌剂处理的腰果树的疾病严重程度显着降低（p < 0.001）0-11.49% 和 0-12.98%和 59.71%）。这项研究的结果表明，所测试的生物防治剂在治疗由尖孢镰刀菌引起的腰果枯萎病方面具有潜力。然而，建议进一步研究以确定生物防治剂的保质期和有效性，特别是在野外环境中，以及各种制剂的功效。
