Trichoderma metabolites as biological control agents against Phytophthora pathogens

Biocontrol Potential of Fungal Endophytes against Fusarium oxysporum f. sp. cucumerinum Causing Wilt in Cucumber

“…against common crop pathogens, including Rhizoctonia solani , Botrytis cinerea , Fusarium oxysporum , and Phytophthora infestans , their results indicated that all endophytic strains were highly effective against many pathogens tested and the most highly effective strains were identified as Aureobasidium pullulans and Paraconiothyrium sporulosum and that the inhibitory effect was due to the production of endophytic bioactive metabolites. Other species, like well-known biological control agent Trichoderma can inhibit the growth of many pathogenic fungi by producing metabolites (Bae et al, 2016). These results suggest that tomato, mangrove, star anise and agarwood harbors diversify endophytic fungi, from which potential biocontrol agents against destructive plant pathogens like F. oxysporum , Verticillium , and B. cinerea , and for promoting growth of cucumber can be screened as these plants have the potential to harbor the endophytic fungi with promising source of different and structurally unprecedented bioactive natural products is unquestionable and continues to attract considerable attention (Debbab et al, 2013; Premalatha and Kalra, 2013).…”

Efecto de biocontrol e inhibición germinativa de Bacillus spp. sobre zoosporas de Phytophthora capsici

“…Tomando en cuenta esta situación, y a que el control químico y la mayoría de las prácticas culturales no representan herramientas efectivas para disminuir la incidencia de daño por este patógeno en plántulas de tomate y chile, el uso de organismos de biocontrol pueden ser una alternativa promisoria (Bae et al, 2016;Thampi y Bhai, 2017).…”

“…de B. amyloliquefaciens mostró una eficacia de biocontrol en plantas de chile tan solo de 38.89%; mientras que, en tomate fue significante con más del 72%; sin embargo, la eficacia de biocontrol de reduce the damage caused by P. capsici in tomato and chili seedlings, the use of biocontrol organisms could be a promising alternative (Bae et al, 2016;Thampi and Bhai, 2017).…”

Biocontrol of PGPR strain Bacillus amyloliquefaciens Ba168 against Phytophthora nicotianae on tobacco

“…Biocontrol of soil-borne pathogens is preferred worldwide, because of the favorable biocontrol efficacy, if applied properly, and the urgent need to introduction environmental friendly alternatives to gradually reducing the use of harmful agrochemicals (9). So far, various P. nicotianae control strains, like Bacillus subtilis Tpb55 (10), Bacillus atrophaeus HAB-5 (11), non-pathogenic binucleate Rhizoctonia fungi (12), Trichoderma (13, 14), Brassica carinata pellets (15), Glomus mosseae and Pseudomonas fluorescens (16), have been evaluated. Among these biocontrol agents, P. fluorescens is one of the most studied PGPR (17), which contributed greatly to the understanding of the mechanisms that are involved in disease suppression.…”
