“…Bacterial Burkholderia GanoEB2 inhibited Ganoderma boninense by colonising the intracellular and intercellular tissue of plant and minimised the chances of the pathogens for both nutrient and niches without causing any harm to the host plant (Kloepper et al 1999;Hallmann et al 2001). Significant disease suppression was also reported for wheat plants endophytically colonised with Bacillus subtilis (Liu et al 2009).…”

Studies by Abdullah et al (1999), Ilias (2000), Sariah et al (2005), and Susanto et al (2005) proved that endophytic fungus, Trichoderma spp., showed high efficacy in controlling the growth of BSR disease in plant house trials and under field condition.…”

“…This concern is particularly acute for genetically engineered bacteria ( Timms- Wilson et al 2004). Augmenting indigenous antagonists in the soil through use of organic amendments, intercropping or crop rotations could be a more ecologically sound alternative to the introduction of specific antagonists that does not raise many of the concerns regarding non-target effects of introduced organisms (Kloepper et al 1999).…”

“…A variety of plant-associated bacteria have been found to enhance plant growth and elicit plant defence mechanisms; many are from the rhizosphere (called rhizobacteria), others from the phyllosphere (leaf surface) and from inside tissues of healthy plants ( Kloepper et al 1999). Some have found that compatible mixtures of rhizobacteria are more effective than a single strain ( Ramamoorthy et al 2001;Jetiyanon & Kloepper 2002;Jetiyanon et al 2003); also a mix of antagonistic bacteria as a seed treatment in combination with foliar biocontrol agents improved the control of bacterial speck (Pseudomonas syringae pv.…”

This paper discusses biotic interactions in agroecosystems and how they may be manipulated to support crop productivity and environmental health by provision of ecosystem services such as weed, pest and disease management, nutrient cycling and biodiversity conservation. Important elements for understanding biotic interactions include consideration of the effects of diversity, species composition and food web structure on ecosystem processes; the impacts of timing, frequency and intensity of disturbance; and the importance of multitrophic interactions. All of these elements need to be considered at multiple scales that depend in part on the range of the movement of the organisms involved. These issues are first discussed in general, followed by an examination of the application of these concepts in agricultural management. The potential for a greater use of ecological management approaches is high; however, owing to the nature of complex interactions in ecosystems, there is some inherent unpredictability about responses to management interventions under different conditions. Such uncertainty needs to be accommodated in the development of recommendations for farm management. This requires an increased emphasis on the effective synthesis of complex and often apparently contradictory information and on field-based adaptive research, monitoring and social learning by farmer/researcher collaborations.

“…La disminución de estos impactos ambientales se logra empleando sistemas de control alternativos; ejemplo de ello es el uso de microorganismos como agentes biocontroladores de fitopatógenos, los cuales, actúan desplazando los agentes infecciosos de forma natural (control biológico) y fortalecen a la especie vegetal atacada. La ventaja de emplear productos biológicos radica en que éstos usualmente no ejercen efectos nocivos al hombre y ambiente (Tarik et al, 2005;Kloepper et al, 1999). Además, representan una alternativa económica en el control y disminución de fitopatógenos (Montesinos et al, 2002;Nandakumar et al, 2002).…”

Artículo original de investigaciónEvaluación del efecto antagonista de un consorcio bacteriano sobre Rhizoctonia solani Kühn en cultivos de arroz. AbstractR. solani is a fungal phytopathogen that attacks rice, generating low yields in its crops. This study evaluated the behavior of a bacterial consortium (Lp) as a bio controller agent against the phytopathogen fungus. The antagonist effect, using in vitro Lp/R. solani dual cultures preparated in potato dextrose agar and nutritive broth media, reached inhibitory levels of 62,0 ± 1% and 58,0 ± 0,5% respectively as compared with the growth of the fungus in absence of Lp. Besides, Lp grew in a minimal mineral medium supplemented with R. solani as the sole carbon source. The antagonist effect was related to an extracellular proteolytic activity present in the cell free supernatants obtained from Lp, which was determined by zymography. In germination experiments, previous incubations of rice seeds during 12 h with Lp, increased the size of plantlets and roots compared to the non treated seeds. By Lp treatment of a rice paddy, at Calabozo, Venezuela, an increase of 44% (equivalent 867kg/ha) was obtained respect to a control rice field (without any treatment). The data indicated Lp consortium could be used as a biocontroller agent against R. solani in rice cultivation.
