Bacterial wilt caused by Ralstonia solanacearum is one of the most devastating diseases in tomato cultivation. This study aimed to evaluate the effect of Bacillus and Trichoderma isolates to manage the bacterial wilt disease. Field experiments were conducted in a randomized complete block design at Mwea and Kabete sites in Kenya. The treatments included 3 Trichoderma; 2 Bacillus isolates; a mixture of T1, T2, and T4; chemical standard; and distilled water as control. Trichoderma and Bacillus isolates were grown on sterilized sorghum grain and cow manure carriers respectively. Antagonist’s inoculation was carried out by dipping tomato plants for 30 min in each treatment suspension. Each treatment was then applied at a rate of 150 ml/plant hole and this was repeated after 35 days. All the treatments significantly reduced bacterial wilt incidence and severity at P ≤ 0.05 than the control at both sites. Trichoderma isolate T1, followed by Bacillus isolate CB64, was the best in reducing the disease incidence by more than 61.66 and 53%, respectively at both sites. Treatment CB64 and T1 had the highest reduction of R. solanacearum population in the soil by 93.17 and 92.07%, respectively. However, control had a pathogen increase of 20.40%. CB64 and T1 performed significantly better compared to the standard, while the mixture of isolates T1, T2, and T4 performed the poorest in all parameters. The treatments also increased the yield of tomato. Results from this study showed that Trichoderma and Bacillus isolates are effective biological control agents for use in management of bacterial wilt.

的效果芽孢杆菌木霉属中番茄(的青枯病的管理物种番茄番茄)领域

青枯雷尔氏菌引起的细菌性枯萎是番茄栽培中最具破坏性的疾病之一。这项研究旨在评估芽孢杆菌和木霉菌分离物对细菌性枯萎病的控制作用。在肯尼亚的Mwea和Kabete基地以随机完整区块设计进行了现场试验。治疗包括3木霉;2种芽孢杆菌分离株;T1,T2和T4的混合物;化学标准 和蒸馏水作为对照。木霉和芽孢杆菌分离株分别在无菌的高粱谷物和牛粪便载体上生长。通过将番茄植株浸入每种处理悬浮液中30分钟来进行拮抗剂的接种。然后以150毫升/孔的速率施行每种处理,并在35天后重复进行。所有处理均在两个位置上均显着降低了细菌萎t的发生率和严重程度(P≤0.05)。木霉菌分离株T1,然后是芽孢杆菌分离株CB64,在两个站点上分别将疾病发病率分别降低61.66和53%以上是最好的。处理CB64和T1在土壤中的茄枯病菌种群减少量最高,分别为93.17和92.07%。但是,对照的病原体增加了20.40%。与标准品相比,CB64和T1的性能要好得多,而分离株T1,T2和T4的混合物在所有参数中的表现最差。这些处理还增加了番茄的产量。这项研究的结果表明,木霉和芽孢杆菌的分离物是用于控制青枯病的有效生物防治剂。比两个站点的控件都差05。木霉菌分离株T1,然后是芽孢杆菌分离株CB64,在两个站点上分别将疾病发病率分别降低61.66和53%以上是最好的。处理CB64和T1在土壤中的茄枯病菌种群减少量最高,分别为93.17和92.07%。但是,对照的病原体增加了20.40%。与标准品相比,CB64和T1的性能要好得多,而分离株T1,T2和T4的混合物在所有参数中的表现最差。这些处理还增加了番茄的产量。这项研究的结果表明,木霉和芽孢杆菌的分离物是用于控制青枯病的有效生物防治剂。比两个站点的控件都差05。木霉菌分离株T1,然后是芽孢杆菌分离株CB64,在两个站点上分别将疾病发病率分别降低61.66和53%以上是最好的。处理CB64和T1在土壤中的茄枯病菌种群减少量最高,分别为93.17和92.07%。但是,对照的病原体增加了20.40%。与标准品相比,CB64和T1的性能要好得多,而分离株T1,T2和T4的混合物在所有参数中的表现最差。这些处理还增加了番茄的产量。这项研究的结果表明,木霉和芽孢杆菌的分离物是用于控制青枯病的有效生物防治剂。在两个站点上,降低疾病发病率分别达到61.66%和53%以上是最好的。处理CB64和T1在土壤中的茄枯病菌种群减少量最高,分别为93.17和92.07%。但是,对照的病原体增加了20.40%。与标准品相比,CB64和T1的性能要好得多,而分离株T1,T2和T4的混合物在所有参数中的表现最差。这些处理还增加了番茄的产量。这项研究的结果表明,木霉和芽孢杆菌的分离物是用于控制青枯病的有效生物防治剂。在两个地点分别使疾病发生率降低61.66%和53%以上是最好的。处理CB64和T1在土壤中的茄枯病菌种群减少量最高,分别为93.17和92.07%。但是,对照的病原体增加了20.40%。与标准品相比,CB64和T1的性能要好得多,而分离株T1,T2和T4的混合物在所有参数中的表现最差。这些处理还增加了番茄的产量。这项研究的结果表明,木霉和芽孢杆菌的分离物是用于控制青枯病的有效生物防治剂。与标准品相比,CB64和T1的性能要好得多,而分离株T1,T2和T4的混合物在所有参数中的表现最差。这些处理还增加了番茄的产量。这项研究的结果表明,木霉和芽孢杆菌的分离物是用于控制青枯病的有效生物防治剂。与标准品相比,CB64和T1的性能要好得多,而分离株T1,T2和T4的混合物在所有参数中的表现最差。这些处理还增加了番茄的产量。这项研究的结果表明,木霉和芽孢杆菌的分离物是用于控制青枯病的有效生物防治剂。
