“…On the other hand, while studies on biological control of Verticillium wilts are available, they are again focused in herbaceous hosts and in just a small number of soil-borne fungi (i.e., Talaromyces, Trichoderma) or bacteria (i.e. Bacillus, Paenibacillus, Pseudomonas, Serratia, Streptomyces) species which have so far been demonstrated to be effective BCA against V. dahliae (Jordan and Tarr 1978;Leben et al 1987;Berg et al 1994;Madi et al 1997;Alström 2001;Nagtzaam et al 1998;Narisawa et al 2002;Tjamos et al 2004Tjamos et al , 2005Antonopoulos et al 2008;Uppal et al 2008;Erdogan and Benlioglu 2010;Meschke and Schrempf 2010).

This bacterium was isolated from oilseed rape rhizosphere, and showed in vitro antagonism against different fungal pathogens, including V. dahliae (Kalbe et al 1996;Berg 2000;Erdogan and Benlioglu 2010). Diverse mechanisms have been proposed to be involved in biocontrol by HRO-C48: production of lytic enzymes such a chitinases and glucanases, antibiotics such as prodigyosine and pyrrolnitrin, siderophores and phytohormones (Kalbe et al 1996;Frankowski et al 2001;Kamensky et al 2003).…”

Verticillium wilt of olive: a case study to implement an integrated strategy to control a soil-borne pathogen

Olive (Olea europaea L.) is one of the first domesticated and cultivated tree species and has historical, social and economical relevance. However, its future as a strategic commodity in Mediterranean agriculture is threatened by diverse biotic (traditional and new/emerging pests and diseases) and abiotic (erosion, climate change) menaces. These problems could also be of relevance for new geographical areas where olive cultivation is not traditional but is increasingly spreading (i.e., South America, Australia, etc). One of the major constraints for olive cultivation is Verticillium wilt, a vascular disease caused by the soil-borne fungus Verticillium dahliae Kleb. In this review we describe how Verticillium wilt of olive (VWO) has become a major problem for olive cultivation during the last two decades. Similar to other vascular diseases, VWO is difficult to manage and single control measure are mostly ineffective. Therefore, an integrated disease management strategy that fits modern sustainable agriculture criteria must be implemented. Multidisciplinary research efforts and advances to understand this pathosystem and to develop appropriate control measures are summarized. The main conclusion is that a holistic approach is the best strategy to effectively control VWO, integrating biological, chemical, physical, and cultural approaches.

“…Then, plates were incubated at 27-29 °C in darkness and after 5 days the growth diameter of the pathogen (distance between the point of placement of fungal disk and actively growing edges of the fungus) was measured. The percentage of growth inhibition was calculated using the method described by Erdogan and Benlioglu (2010). This experiment was conducted twice.…”

Article Info Received : 08.12.2015 Accepted : 20.01.2016 The aim of this work is to study the ability of several isolates belonging to Rhizobacteria (Pseudomonas and Bacillus) collected from several chickpea growing areas in Algeria, to control the mycelium growth of Fusarium oxysporum f. sp. ciceris. Interesting isolates were characterized for their morphological characteristics, physiological and biochemical activities as potential bio-control agent. Fungal inhibition tests were performed using plate assay and each isolate were tested for the production of protease, cyanide hydrogen, indole acetic acid, antifungal volatile and extracellular compound. According to API 50 CH, we are able to identify six Bacillus species (B. subtilis, B. circulans, B. lentus, B. aneurinilyticus, B. firmus, B. licheniformis; and with API 20NE test we have identified three Pseudomonas species (P. aeruginosa, P. luteola, P. fluorescens). The ability of bacterial isolates was varied in production of Protease, Gelatinase, Amylase, Cellulase, Acid Indole acetic, Lipase, Catalase and Cyanid Hydrogen. This is traduced in different rate of inhibition growth due to various extracellular compounds, where B61 (Bacillus aneurinilyticus) and P39 (Pseudomonas luteola) and P70 (Pseudomonas fluorescens) were the most efficient with 77 and 55.5% respectively, while B39 (Bacillus firmus) and P41 (Pseudomonas luteola) were the most efficient by volatile compounds with 70.5 and 77.5% respectively. Our results indicate that these bacteria isolates can be used in the biocontrol of Fusarium oxysporum f. sp. ciceris.

Abstract:In this study, about 112 isolates of Streptomyces were isolated from chickpea rhizospheric soils. Among the isolated strains, five showed strong inhibitory effects against chickpea Fusarium wilt caused by Fusarium oxysporum f. sp. ciceris in vitro using plate assay and selected for further studies. The selected strains were identified as Streptomyces spp. based on morphological and biochemical characterization as well as 16S rDNA sequences analysis. Our results assigned them to strains related to genus of Streptomyces.In vitro, antagonistic effects of Streptomyces strains against the disease were evaluated through the dual-culture method, volatile and non-volatile metabolites, siderophore, protease and chitinase production. All bacterial strains inhibited mycelial growth of the pathogen ranging from 26 to 44.2% in dual culture assay. The non-volatile extract of five of the Streptomyces strains inhibited more than 50% growth of the pathogen, whereas volatile compounds were less effective on mycelial growth inhibition (20.2 to 33.4%). The ability of the biocontrol agents to produce siderophore and protease were varied, whereas, production of chitinase was detected for all strains. Results of the greenhouse assay indicated that all biocontrol agents reduced disease severity (ranging from 38.7 to 54.8%).Accordingly, strain KS62 showed higher control efficacy (54.8%). In addition, the biomass of chickpea plants (plant height and dry weight) significantly increased in plants treated with Streptomyces strains compared to non-bacterized control. The results of this study showed that it may be possible to manage chickpea Fusarium wilt disease effectively by using Streptomyces species, as biocontrol agents. Therefore, evaluating their efficiency under field conditions is needed.
