“…to F. graminearum is tested in vitro by Foroutan (2013), and mycelial growth of F. graminearum was inhibited from 28.5 -58.8% which is much lower than in this study (60.5 -71.1%). Additionally, effectiveness of Trichoderma species in contact growth inhibition of F. verticillioides was confirmed by Sempere &Santamarina (2009) andCalistruet al (1997) as well as in this study. Figure 1B indicates that there is no significant change in RGI scored on 14 th and 21 st day for A.…”

“…T. harzianum exerted two mechanisms synergically over F. culmorum in nearly all conditions (0.995, 0.98 and both temperatures, 0.95 and 25ºC): mycoparasitism and competition for space and nutrients. The same results were obtained when T. harzianum were co-cultured with other rice species in these environmental conditions , 2008, 2009b. T. harzianum could be a good biological control agent of the rice pathogens in a future but more research is necessary for this consideration.…”

Colonies of Trichoderma harzianum were inhibitory of strains of Fusarium culmorum in different environmental conditions. The degree of inhibition was dependent on the temperature and water activity treatments. Nearly all macroscopic analysis of the Petri plates revealed that Trichoderma harzianum against F. culmorum was a competitor for space and nutrients. In these conditions the microscopic study showed that Trichoderma harzianum was a mycoparasite. The possible production of cell-wall degrading enzymes by Trichoderma harzianum and its effect on mycelia of F. culmorum are discussed.

“…that can counteract only one or few targeted pathogens. The mechanisms of biological control include direct parasitism or mycoparasitism [4][5][6][7][8] from physical penetration, secretion of numerous lytic enzymes [4,[9][10][11][12][13][14], antibiosis [4,[15][16][17][18][19], competition for nutrients or ecological niches [13,15,16,20]. The classification becomes complicated when consideration is made to the indirect positive effects that a MBCA can have on the plant.…”

Governing bodies throughout the world, particularly in Europe, are now implementing legislative mandates with the objective of decreasing dependence on pesticides in agriculture to increase consumer and environmental safety. In order to reduce the risks associated with pesticide applications and reduce dependency on their use, Directives will promote low pesticide-input by implementing integrated pest management (IPM), and provide the means to establish the necessary conditions and measures to employ these practices, as well as to ensure security of commercial products. One approach includes the use of biological control agents and their products as alternatives to synthetic agro-chemicals. Trichoderma spp. are widely studied fungi and are among the most commonly used microbial biological control agents (MBCAs) in agriculture. They are presently marketed as bio-pesticides, biofertilizers, growth enhancers and stimulants of natural resistance. The efficacy of this fungus can be attributed to their ability to protect plants, enhance vegetative growth and contain pathogen populations under numerous agricultural conditions, as well as to act as soil amendments/inoculants for improvement of nutrient ability, decomposition and biodegradation. The living fungal spores (active substance) are incorporated in various formulations, both traditional and innovative, for applications as foliar sprays, pre-planting applications to seed or propagation material, post-pruning treatments, incorporation in the soil during seeding or transplant, watering by irrigation or applied as a root drench or dip. Trichoderma-based preparations are marketed worldwide and used for crop protection of various plant pathogens or increase the plant growth and productivity in diverse cultivated environments such as fields, greenhouses, nurseries; in the production of a variety of horticultural, fruits, trees and ornamental crops. A survey was conducted of Trichoderma-containing products found on the international market to obtain an overall perspective of the: 1) geographical distribution, 2) product composition and identity of Trichoderma species selected, 3) contents combined with Trichoderma in the products -other microbial species or substances in the mix, 4) number of products available globally and geographically, 5) number of products registered or having use specifications, 6) product formulations and applications, 7) manufacturer claims -target use, target pests, product type and effects of applications. The largest distribution of Trichoderma bioproducts is found in Asia, succeeded by Europe, SouthCentral America and North America. The majority of the labels indicated fungicidal properties, but only 38% of the marketed merchandise are registered. Ten Trichoderma species are specifically indicated, but many labels indicate a generic Trichoderma sp. or spp. mix in the list of ingredients. The most common formulation is a wettable powder, followed by granules. Generally, Trichoderma are applied to the seed or propagation material at...
