Cocoa production is affected by the black pod disease caused by several Phytophthora species that bring, about each year, an estimated loss of 44% of world production. Chemical control remains expensive and poses an enormous risk of poisoning for the users and the environment. Biocontrol by using antagonistic microorganisms has become an alternative to the integrated control strategy against this disease. Trichoderma viride T7, T. harzanium T40, and T. asperellum T54, which showed in vivo and… Expand
Involvement of lytic enzymes and secondary metabolites produced by Trichoderma spp. in the biological control of Pythium myriotylum
There was significant correlation between the production of total polyphenol and flavonoid content and the antagonistic effects of the tested strains and the antimicrobial activity of the organic extracts was determined using the poisoning method. Expand
Antifungal Activity of Chemical Constituents from Piper pesaresanum C. DC. and Derivatives against Phytopathogen Fungi of Cocoa
The preliminary structure–activity relationship allowed us to establish that prenylated chains and the carboxyl group are important in the antifungal activity of benzoic acid derivatives. Expand
The microbial role in the control of phytopathogens—an alternative to agrochemicals
In this environment, several species of fungi and bacteria act as biocontrol agents, weakening the development of plantation enemies through antibiosis, nutrient competition, predation, parasitism, interference with molecular signaling, and induction of systemic resistance in plants. Expand
Bioconversion of antifungal viridin to phytotoxin viridiol by environmental non-viridin producing microorganisms.
Biotransformation of viridin, an antifungal produced by biocontrol agent, with non-viridin producing microorganisms is studied. The results show that some environmental non-targeted microorganismsExpand
Manejo de la pudrición parda de la mazorca (Phytophthora palmivora) en cacao por aplicación conjunta de prácticas culturales y químicas
The removal of diseased pods constitutes the basis of the management of Phytophthora palmivora in a susceptible clone such as ccn51, by allowing a 43.13% decrease in the incidence in Imc-7 in relation to imc-2. Expand
Bioactive compounds, antioxidant and antifungal activity of medicinal plants of Western Ghats of Karnataka against Phytophthora blight disease of papaya (Carica papaya L.)
The results of the present study showed that all the four plants have high potential antioxidant activity to fight against the Phytophthora blight disease of papaya. Expand
New cyclopentenoneacrylic acid derivatives from a marine-derived fungus Trichoderma atroviride H548
Three new cyclopentenoneacrylic acid derivatives, trichodermacid A,trichodermester A and B, together with thirteen known compounds, were isolated from an ethyl acetate extract of Trichoderma atroviride H548, a fungus derived from mangrove sediment. Expand
Fermented crop straws by Trichoderma viride and Saccharomyces cerevisiae enhanced the bioconversion rate of Musca domestica (Diptera: Muscidae)
F fermenting crop straw with T. viride and S. cerevisiae represented an efficient strategy that enhanced crop straw bioconversion and improved the rearing capacity of the housefly larvae, which could be used as proteinaceous feed in poultry and aquaculture industries. Expand


Antagonist potential of Trichoderma indigenous isolates for biological control of Phytophthora palmivora the causative agent of black pod disease on cocoa ( Theobroma cacao L.) in Côte d'Ivoire
The biodiversity of Trichoderma isolates from cocoa rhizosphere in cocoa production areas of Cote d’Ivoire, and their antagonist potential with Phytophthora palmivora using in vitro assays andExpand
Effectiveness of biological control of Phytophthora capsici in pepper by Trichoderma asperellum strain T34
T34 is a useful biological alternative to chemicals for the control of P. capsici in pepper and reduced disease in most of the assayed situations, while etridiazole was effective only when applied at the same time as the pathogen. Expand
Abstract Trichoderma spp. have been widely used as antagonistic fungal agents against several pests as well as plant growth enhancers. Faster metabolic rates, anti-microbial metabolites, andExpand
Trichoderma from Aceh Sumatra reduce Phytophthora lesions on pods and cacao seedlings
Abstract The cocoa tree, Theobroma cacao L., suffers large yield losses in Aceh Indonesia due to the disease black pod rot, caused by Phytophthora spp. Despite having the largest area under cacaoExpand
Detection of viridiofungin A and other antifungal metabolites excreted by Trichoderma harzianum active against different plant pathogens
Contrary to several reports in the literature, VFA proved to be fungistatic rather than fungicidal, and neither VFA nor the other Trichoderma metabolites, such as 6PAP, F416 and F516, exhibited any antibacterial activity against Gram-positive and Gram-negative bacteria. Expand
Biocontrol potential of Trichoderma martiale against the black-pod disease (Phytophthora palmivora) of cacao.
The results indicate a clear-cut potential of the T. martiale ALF 247 to be used for control of Black-Pod Rot of cacao, although further studies are required to render this isolate technically and economically efficient as a biocontrol agent on agronomic scale. Expand
Trichoderma metabolites as biological control agents against Phytophthora pathogens
The potential for use of Trichoderma metabolites as biological control agents against Phytophthora pathogens was showed and the strongest inhibitory activities were shown from Trichodma atroviride/petersenii and Trichodes virens. Expand
Synergistic effect of Trichoderma-derived antifungal metabolites and cell wall degrading enzymes on enhanced biocontrol of Fusarium oxysporum f. sp. cucumerinum
It is concluded that T. asperellum CCTCC-RW0014 was the highly potential strain to control the FOC, providing scope for a further study on the mechanism of interaction between Trichoderma derived compounds and host plants. Expand
Isolation and identification of mycoparasitic isolates of Trichoderma asperellum with potential for suppression of black pod disease of cacao in Cameroon
Data presented here demonstrate for the first time the potential of mycoparasitic isolates of T. asperellum for suppression of black pod of cacao in Cameroon. Expand
Antibiotics and enzymes produced by the biocontrol agent Streptomyces violaceusniger YCED-9
A potential for biological control of diseases caused by P. infestans was also suggested by strain YCED-9’s strong in vitro antagonism towards pathogenic isolates of this fungus. Expand
