“…Reinforcing results of this study, Corrêa et al (2014) also observed efficiency variations when the same BCAs of this study to control five isolate of Curtobacterium flaccumfacien spv. flaccumfaciens in common bean were used.…”

“…The wider spectrum of action and greater control efficacy also can be achieved by combining agents that induce resistance and produce antibiotic as shown for Bacillus pumilus (INR7), Curtobacterium flaccumfaciens (ME1), B. subtilis (GB03) which in different combinations controlled Pseudomonas syringaepv. lachrymans, Erwinia tracheiphila and Colletotrichum orbiculare (Raupach and Kloepper, 1998) or combining lytic and antibiotic activities with systemic resistance to control bacterial wilt, Fusarium wilt, charcoal rot and angular leaf spot of common beans (Corrêa et al, 2014). The data of this study show that the independent of the virulence of the pathogen´s strain there was strain-BCA interaction, which shows the importance of selecting a BCA or a combination of BCAs with wider spectrum of action, allowing for greater effect under different situations, thus adding to the product stability (Boer et al, 2003;Mercier et al, 2006).…”

“…However, the studies that evaluate the efficacy of BCA in controlling the diseases caused by different strains of the same pathogen are rare. Corrêa et al (2014) pointed out that the control of bacterial pathogens by bacterial BCA may be strain dependent, leading to variability in control efficacy. In vitro evaluation of BCA to control bacterial blight of beans gave varied results when confronted with different strains of Xap (Silva et al, 2008), although in vitro studies are not sufficient to evaluate the efficacy of a BCA (Köhl et al, 2011).…”

The bacterial biocontrol agents (BCAs) treatments were used for seed microbiolization; the bacterial biocontrol agents (BCAs) used selected from previous study on the control of Xanthomonasaxonopodis pv. phaseoli Xap) includes: Bacillus (DFs093, DFs348 and DFs769), Pseudomonas (DFs513, DFs831 and DFs842), Rhodococcus (DFs843 and DFs912), and the combinations C01 (DFs093+DFs769+DFs831), C02 (DFs093+DFs769+DFs842) and C03 (DFs093+DFs769+DFs348). Sixteen (16) Xap strains were collected from several Brazilian regions, and were inoculated in cotyledonary leaves. The symptom development was followed for 10 days. The treatments were compared by the area under the disease progress curve for disease incidence, severity, and index. In general, majority of the BCAs reduced, to some degree, the disease caused by different Xap strains. The combination C01, and the isolate DFs831 resulted in highest mean disease control. The data from this study suggest a relationship between the region of origin of Xap strain and the efficacy of BCA to control the disease caused by it. The use of combinations of these organisms increased the efficacy of the biocontrol of several strains of the same pathogen. A strain-BCA interaction was shown by data collected from this study, which evidence the importance of selecting a BCA or a combination of BCAs with a wider spectrum of action.

“…P. fluorescens reduced the severity of Fusarium (mainly F. oxysporum)-induced wilt on a variety of crops [32][33][34][35][36]. Pseudomonads produce several antifungal metabolites including cyclic lipopeptides, phloroglucinols, phenazines, pyoluteorin, and pyrrolnitrin [37] or may induce local or systemic resistance in the plant against the pathogen [38].…”

Pitch canker, caused by the fungus Fusarium circinatum, is a major disease of Pinus radiata currently controlled to some extent in nurseries by good hygiene and application of synthetic fungicides. The aim of this study was to evaluate alternative strategies to control fungal infections in nurseries and young pine plantations. The antagonistic effects of biocontrol bacteria and essential oils against F. circinatum in vitro and in young P. radiata trees were assessed. Pseudomonas fluorescens, Erwinia billingiae, and Bacillus simplex reduced the growth of the fungus in vitro by 17%-29%, and decreased the density of the mycelial mat. In young P. radiata trees, the length of F. circinatum lesions was reduced by 22%-25% by the same bacterial strains. Direct application of cinnamon and/or clove essential oils to wounds in stems of two-year-old P. radiata trees also limited the damage caused by F. circinatum. Lesion length was reduced by 51% following treatment with cinnamon oil (10% v/v), and by 45% following treatment with clove oil (15% v/v) or a combination of both oils. However, the oils were toxic to younger trees. The biocontrol bacteria and essential oils show promise as prophylactic treatments to reduce the devastating effects of F. circinatum on P. radiata.
