“…This result was corroborated by the significant positive correlations (P < 0Á001) that were observed between DS and FOL abundance. These findings were supported by previous studies that showed that Fusarium abundance in the cucumber and banana rhizosphere was reduced after BCA treatments (Qiu et al 2012;Shen et al 2015;Fu et al 2017). Furthermore, FOL abundance was very low after the treatment with inoculated compost (CM), thus indicating the positive effect of organic amendments in reducing the impact of Fusarium wilt agents, as previously pointed out by Yogev et al (2006), Bonanomi et al (2010) and Pugliese et al (2011).…”

Aims The response of rhizosphere and bulk soil indigenous microbial communities focusing on nitrifiers was evaluated after the application of different biological control agents (BCAs; Bacillus, Trichoderma, Pseudomonas) and compost in controlling lettuce Fusarium wilt. Methods and Results Experiments were conducted ‘in situ’ over two lettuce cropping seasons. Total fungal, bacterial and archaeal populations and the nitrifiers were analysed using quantitative polymerase chain reaction method. The pathogen, Fusarium oxysporum forma specialis lactucae (FOL), Bacillus, Trichoderma and Pseudomonas and three antifungal genes (chiA, 2,4‐diacetylphloroglucinol ‐ phlD and HCN synthase ‐ hcnAB genes) were also assessed. Quantitative data were corroborated with disease severity (DS), potential nitrification activity and soil chemical parameters. The application of BCAs and compost resulted in the disease reduction by as much as 69%, confirmed by significant negative correlations between Bacillus subtilis, Trichoderma and Pseudomonas sp. abundances and DS. The FOL presence in the untreated control resulted in the nitrifiers niche differentiation. Conclusions The used treatments were efficient against Fusarium wilt and did not influence negatively the nontarget microbial communities. Significance and Impact of the Study The use of BCAs and compost appears as an effective and safe strategy to implement sustainable agricultural practices.

“…in maize could significantly promote plant growth, change root structure, and increase root activity. Shen [56], Fu [57], and Xiong [58] demonstrated that a Trichoderma agent stimulated banana root growth, promoted plant growth, and increased fruit yield. Hung [59] and Zhang [30] showed that a mixture of organic fertilizer and a Trichoderma agent could significantly improve plant growth and crop yield.…”

Trichoderma spp. are proposed as major plant growth-promoting fungi that widely exist in the natural environment. These strains have the abilities of rapid growth and reproduction and efficient transformation of soil nutrients. Moreover, they can change the plant rhizosphere soil environment and promote plant growth. Pinus sylvestris var. mongolica has the characteristics of strong drought resistance and fast growth and plays an important role in ecological construction and environmental restoration. The effects on the growth of annual seedlings, root structure, rhizosphere soil nutrients, enzyme activity, and fungal community structure of P. sylvestris var. mongolica were studied after inoculation with Trichoderma harzianum E15 and Trichoderma virens ZT05, separately. The results showed that after inoculation with T. harzianum E15 and T. virens ZT05, seedling biomass, root structure index, soil nutrients, and soil enzyme activity were significantly increased compared with the control (p < 0.05). There were significant differences in the effects of T. harzianum E15 and T. virens ZT05 inoculation on the growth and rhizosphere soil nutrient of P. sylvestris var. mongolica (p < 0.05). For the E15 treatment, the seedling height, ground diameter, and total biomass of seedlings were higher than that those of the ZT05 treatment, and the rhizosphere soil nutrient content and enzyme activity of the ZT05 treatment were higher than that of the E15 treatment. The results of alpha and beta diversity analyses showed that the fungi community structure of rhizosphere soil was significantly different (p < 0.05) among the three treatments (inoculated with T. harzianum E15, T. virens ZT05, and not inoculated with Trichoderma). Overall, Trichoderma inoculation was correlated with the change of rhizosphere soil nutrient content.

“…This pathogen can grow and survive in soil for 10-15 years and infect more than one hundred plants, including the cucumber (Cucumis sativus L.) [5], watermelon (Citrullus L.) [6,7], cotton (Gossypium spp.) [8], and banana (Musa nana L.) [9,10]. Susceptible plants can be infected through the root during all stages of growth, causing disease of the vascular bundle, gradually turning leaves yellow, and eventually resulting in plant wilting [11].…”

Evaluation of Soil-Applied Chemical Fungicide and Biofungicide for Control of the Fusarium Wilt of Chrysanthemum and Their Effects on Rhizosphere Soil Microbiota

et al. 2018

Chemical fungicides are a frequently used intervention for the control of the Fusarium wilt of chrysanthemum, but are no longer considered environmentally friendly. However, the biofungicides offer one of the best alternatives to reduce the use of chemical fungicides. In this study, a series of two-year greenhouse experiments were conducted to evaluate the soil-applied chemical fungicide (dazomet, DZ) and biofungicide (biocontrol agent combined with B. subtilis NCD-2, BF) for controlling the Fusarium wilt of chrysanthemum and its effects on rhizosphere soil microbiota. The results indicated that DZ and BF showed good control efficacy of Fusarium wilt of chrysanthemum in the two-year application evaluation. However, the DZ treatment significantly decreased the soil catalase and urease activities compared with the control, while BF showed a significant increase in bacterium/fungus ratios (B/F), soil urease and acid phosphatase activities. Abundances of potential plant pathogens F. oxysporum, Rhizoctonia zeae and Rhizoctonia solani were also lower, while potential plant-growth-promoting micro-organisms like the Rhizobiales bacterium and Mariniflexile sp. were higher in the BF treatment than in the control. Our findings suggested that the overall effect of the soil biota on chrysanthemum growth was more positive and stronger in the BF treatment than in the DZ treatment.
