Grain legumes are a cost-effective alternative for the animal protein in improving the diets of the poor in South-East Asia and Africa. Legumes, through symbiotic nitrogen fixation, meet a major part of their own N demand and partially benefit the following crops of the system by enriching soil. In realization of this sustainability advantage and to promote pulse production, United Nations had declared 2016 as the ''International Year of pulses''. Grain legumes are frequently subjected to both abiotic and biotic stresses resulting in severe yield losses. Global yields of legumes have been stagnant for the past five decades in spite of adopting various conventional and molecular breeding approaches. Furthermore, the increasing costs and negative effects of pesticides and fertilizers for crop production necessitate the use of biological options of crop production and protection. The use of plant growth-promoting (PGP) bacteria for improving soil and plant health has become one of the attractive strategies for developing sustainable agricultural systems due to their eco-friendliness, low production cost and minimizing consumption of non-renewable resources. This review emphasizes on how the PGP actinobacteria and their metabolites can be used effectively in enhancing the yield and controlling the pests and pathogens of grain legumes.

“…Al respecto, diversos autores manifiestan que los actinomicetos son una alternativa con gran potencial para ser usados como agentes de control biológico de Fusarium spp. (Gopalakrishnan et al, 2011), incluyendo a F. equiseti, y otros hongos fitopatógenos (Crawford et al, 1993;Al-Askar et al, 2011;Dávila Medina et al, 2013;Xue et al, 2013;Evangelista-Martinez, 2014 As for the in vitro antagonistic capacity against F. equiseti from the different isolates of the actinomycete, 14 completely inhibited the growth of F. equiseti at tenth day postconfrontation (Tables 2 and 3), possibly by the fungistatic or fungicidal action due the production of antibiotics or biocides diffusing through the medium (Fonseca-Ardila et al, 2011). In this regard, several authors state that actinomycetes are an alternative with great potential as biological control of Fusarium spp.…”

Los árboles de manzano Malus domestica, Borkh. son susceptibles al ataque de una gran diversidad de f itopatógenos, entre los que se encuentran los hongos causantes de enfermedades radiculares, los cuales son controlados con fungicidas sintéticos. Sin embargo, debido a su aplicación indiscriminada, se ha reducido su efectividad y uso. Una alternativa para revertir esta problemática, es el control biológico, mediante la integración de microorganismos antagónicos, por lo que el objetivo del estudio fue aislar actinomicetos nativos de suelos en huertos de manzano del estado de Chihuahua, México, con actividad antagónica a Fusarium equiseti. El estudio fue realizado en el Centro de Investigación en Alimentación y Desarrollo, A.C. (CIAD), Unidad Cuauhtémoc, Chihuahua durante 2013-2014. Para lo cual, se recolectaron muestras de suelo cercano a la rizosfera de árboles de manzano en huertos de cuatro municipios productores del estado de Chihuahua. Para el aislamiento de los actinomicetos, se realizaron diluciones seriadas de las muestras de suelo en agua peptonada estéril y colocándolas por la técnica de difusión en placa, en diez medios de cultivo artificiales semi-selectivos. Las colonias de actinomicetos fueron aisladas y purificadas para posteriormente ser confrontadas in vitro contra el hongo fitopatógeno F. equiseti. Se obtuvieron 710 aislados, dentro de los cuales 222 presentaronactividadantagónicaaestehongofitopatógeno al día 5 post-confrontación y 69 conservaron el antagonismo al día 10 post-confrontación. La alta abundancia de aislados y la proporción que mostró antagonismo a F. equiseti, muestra el potencial y la oportunidad de evaluarlos in vitro e in vivo contra una gran diversidad de hongos y bacterias fitopatógenas del manzano, así como de otros cultivos de interés agrícola.

In our earlier investigation, a fungal isolate Penicillium citrinum VFI-51 and its secondary metabolite was reported to have antagonistic potential against Botrytis cinerea, the causative agent of Botrytis gray mold disease in chickpea. In the present investigation, P. citrinum VFI-51 was further evaluated for its antagonistic potential against Macrophomina phaseolina, the causative agent of charcoal rot in sorghum. P. citrinum VFI-51 inhibited M. phaseolina in both dual culture as well as secondary metabolite production assays. In the in vivo blotter paper assay, under light chamber conditions, P. citrinum VFI-51 controlled 85% of the charcoal rot disease on the roots when compared to the positive control. Under greenhouse conditions, when M. phaseolina was inoculated by tooth pick method in to the stalk of sorghum plant, the charcoal rot disease was controlled by 75% in P. citrinum VFI-51 treatment over the positive control. This study demonstrates the biocontrol potential of P. citrinum VFI-51 against charcoal rot of sorghum.
