“…Co-inoculation of a mixture (1:10) of Clonostachys rosea and Trichoderma spp. on cocoa pods, temporarily suppressed C. rosea, whereas two weeks after application, C. rosea was the dominant and persistent pod colonizer (Krauss et al, 2013). However, these interactions may not be always antagonistic.…”

“…Thus, antagonistic interactions between benefi cial fungal strains could occur and decrease the effi cacy of the treatment. Evaluation of in vitro interactions between Clonostachys and Trichoderma isolates revealed the dominant antagonistic activity of Clonostachys over Trichoderma strains suggesting that these two mycoparasites may be incompatible (Krauss et al, 2013).

Summary Plant Growth Promoting Microorganisms or Plant Probiotics (PGPMs) constitute a promising solution for agricultural sustainability. The concept that inoculation of PGPM mixtures may perform better in enhancing agricultural production than single strain application dates back to the discovery of plant growth rhizobacteria (PGPR) and is gaining ground in our days. This shift is highlighted by the increasing number of research publications dealing with the positive impact of microbial mixtures in promoting plant growth, controlling plant pathogens, as well as providing abiotic stress tolerance. The continuous deposition of patents as well as commercially available formulations concerning bioprotective and/or biostimulant multistrain mixtures also underlines this shift. A major issue in engineering an effective and consistent synthetic multistrain mixture appears to be the compatibility of its components. The present review provides a thorough literature survey supporting the view that treatment of plants with compatible multistrain mixtures generally exerts a better effect in plant growth and health than single-strain inoculation. Our study focuses on multistrain mixtures based on Pseudomonas, Bacillus and beneficial fungal strains, while commercial products are also being referred.

“…Endophytic fungi have been investigated since they are broadly recognized for their capacity to penetrate and colonize the host, where they promote the synthesis of biological compounds that favor the plant growth (13). However, biocontrol agents have limitation in applications due to their outstanding pathogen specificity (10). This makes necessary their isolation from the ecosystem to where they are going to be applied, with the purpose of increasing their effectiveness.…”

Symbiotic and endophytic fungi as biocontrols against cocoa (Theobroma cacao L.) phytopathogens

Cocoa (Theobroma cacao L.) is a tropical tree, seriously affected by fungal diseases. To control several pathogens, biological methods are prescribed since they are friendly to the environment and easy to use. The main objective of this study was to assess the biocontrol effect of two native strains, Trichoderma viride and Botryosphaeria quercum, on phytopathogens such as Phytophthora palmivora and Moniliophtora roreri, causal agents of black pod and frosty pod rot diseases, respectively. In addition, biocontrolers were faced on potential mycotoxigenic fungi such as Aspergills flavus and Fusarium solani, which are very common on cocoa. The Bio-Control Index (BCI) was calculated to determine the in vitro biocontrol effect against the biocontrole contra quatro fitopatógenos. Os resultados indicaram que o melhor agente de controle biológico de fitopatogenos era B. quercum, que mostra 82,3% de BCI e 80,7%, 63,3% e 59,7% para cad a um dos fitopatógenos testados, respectivamente. A competição por substrato foi a estratégia utilizada no controle biológico. As estirpes, provenientes do Departamento de Santander e Santander Norte apresentaram a maior inibição percentual média. Este estudo é um inicial para sobre o poten c ial endófito e antagonística de fungos, capazes de colonizar as especificamente bagas de cacau e solo. Assim, estas estirpes podem ser indicadas uma alternativa eficiente contra fitopatógenos de cacau importantes. Palavras-chave: Cacau, patógenos,cogumelos, biocontroleCocoa (Theobroma cacao L.) is a tropical American tree flowering all year long and bearing a fruit known as pod. Colombia is the ninth producer in the world and the third one in Latin America, after Brazil and Ecuador. Estimated projections indicate that by 2021 Colombia might produce 285,600 Mg cocoa, as cocoa tree plantations are expected to reach over 230,000 ha (11); however, 50% to 90% cocoa production is affected by fungal diseases (2,4). The most prevailing infections are frosty pod rot (caused by the fungus Moniliophthora roreri) and black pod (the etiological agent of which is Phytophthora sp.), both causing cocoa crop losses of up to 100% (15). In addition, there are secondary infections caused by phytopathogens like Aspergillus and Fusarium that attack opportunistically as cocoa deteriorates, thus accelerating pod degradation and leaving traces of mycotoxins (3).To reduce the effects of fungal phytopathogens, cocoa growers apply good cropping practices, sometimes combined with the use of fungicides. The first method is easy to apply but labor demanding and is only economically viable if the cocoa price in the market is high (8). In the case of fungicides, they certainly protect the plant

The present studies aim at determining the antagonistic effect of selected fungi species occurring in the soil under carrot cultivation towards Altenaria dauci (J.G. Kühn) J.W. Groves & Skolko, Alternaria radicina Meier, Drechsler & E.D. Eddy, Fusarium oxysporum E.F. Sm & Swingle, Rhizoctonia solani J.G. Kühn and Sclerotinia sclerotiorum (Lib.) de Bary. The field experiment considered cover crops (oats, tansy phacelia and vetch). The control consisted of traditional carrot cultivation (without cover crops). Statistically, the smallest population of fungi was found in 1 g of soil dry weight after the application of oats, and a slightly bigger – after tansy phacelia and vetch. The largest population of fungi was obtained in the traditional cultivation of carrot. Cover crops contributed to the increase of the population of antagonistic Clonostachys spp., Myrothecium spp., Penicillium spp. and Trichoderma spp. in the soil. Regardless of the experimental treatment, those antagonistic fungi were the most effective in limiting the growth of S. sclerotiorum, A. dauci and A. radicina. The effect of those fungi was a little smaller towards F. oxysporum and R. solani. Oats as a cover crop had the best effect on the antagonistic activity of the studied fungi occurring in the soil environment of carrot.
