“…Attention has also been drawn to those components that their manipulation may lead to a more sustainable bean production and improve organic cultivation. The impacts of animal manures (Sumner et al 2002), fungicidal treatment of seed (Papavizas and Lewis 1975), herbicides (Mussa and Russell 1977), irrigation system (Miller et al 1980) and seedbed (Snapp et al 2003;Valenciano et al 2006) on the bean-Fusarium pathosystem have been reported previously. However, the contribution of farmers' operations to the establishment of bean-FRR epidemics is still largely unknown.…”

“…Snap beans grown on raised beds had a lower FRR and greater yield compared to flat beds in a FSP-inoculated soil (Snapp et al 2003). Elsewhere, raised beds reduced plant growth and intensified bean root rots, probably because of deeper sowing and delayed emergence (Valenciano et al 2006). Based on the present findings, a lower FRR index and 50% greater productivity were detected in beans sown on flat lands compared with raised beds.…”

Restricting Fusarium root rot (FRR) epidemics and improving productivity using fewer chemicals is a major concern in bean-growing regions. The main purpose of this research was to identify the planting strategies associated with FRR development and seed production in bean crops. A 2-year study of 122 commercial bean farms in four major producing regions in Zanjan, Iran, was performed to characterize the associations of farming indicators with FRR and productivity. Linear mixed-effect models, contingency tables and correspondence analyses were used to describe the variables relationships. Low disease and high productivity were linked to herbicide and manure applications, fungicidal treatment of seeds, manual sowing and sprinkler irrigation. Furrow irrigation, mechanical sowing, planting on raised seedbeds, the lack of fertilizer and herbicide use accounted for high disease and low seed production. The results of the study provide further evidence of factors contributions to the wider FRR spread over bean-cropping systems. Overall, this suggests that the selected composition of planting strategies can improve bean production and reduce FRR intensity.

Trichoderma spp. are fungal species in a certain natural suppressive soil prevents the plant from infectious diseases caused by soil-borne pathogens. Among these soils borne pathogen, the fungus Rhizoctonia solani (R. solani) causes serious damages to economically significant crops and trees. The control strategies such as breeding for resistant cultivars, crop rotations, and application of fungicides are insufficient to manage diseases caused by R. solani because it persists in soil by producing sclerotia which is a hard-resistant structure. Moreover, fungicides are now unacceptable as they are not environment-friendly. The Trichoderma spp. are the potential biocontrol agents which inhibit R. solani by direct confrontation through mycoparasitic or antibiosis or competition as well as inducing plant defense responses. In this review paper, we provide first comprehensive report of a biological control activity (BCA) of Trichoderma spp. against various diseases caused by R. solani. We also report the cloning and functions of genes or proteins of Trichoderma spp. associated with suppression of diseases caused by a plant pathogen. Nevertheless, fast paced current research regarding Trichoderma spp. is required to fully exploit their actual potential against diseases caused by R. solani under field conditions.

“…Root rot caused by the fungus Rhizoctonia solani Kühn [teleomoph Thanatephorus cucumeris (Frank) Donk)] is among the major diseases affecting common bean in Argentina and other bean growing areas globally (Abawi, 1989;Mathew and Gupta, 1996;Valenciano, 2006;Naseri, 2008), particularly in regions with low soil fertility, characterized by limited crop rotation and intensive seasonal bean production (Micklas et al, 2006). High inoculum levels of the pathogen affect seed germination and seedling development.…”

The objective of this study was to perform the molecular and pathogenic characterization of Rhizoctonia solani in bean seed and soil samples from fields with root rot symptoms in northwestern Argentina. Fifty-two Rhizoctonia spp. isolates were collected in ten naturally infested bean fields and characterized by morphological traits, DNA sequencing, and pathogenicity. The mycelium color, the pattern of sclerotia formation, and the number of nuclei per hyphal cell were determined for each isolate. According to the variability in the rDNA-ITS region, isolates were identified as R. solani (85%), Waitea circinata var. zeae (Rhizoctonia zeae) (2%) and Rhizoctonia spp. (13%). Most isolates of R. solani (92%) were found to belong to the anastomosis group (AG) AG 4, including seven AG 4 HG-I and nine AG 4 HG-III isolates. AGs obtained from soil samples were more variable than those obtained from seed samples. Molecular identification of the isolates was in agreement with their morphological characterization. In addition, aggressiveness of the isolates towards bean seedlings was assessed in the greenhouse. Four virulence categories were defined according to the disease reaction on root and foliar tissues, which showed great variability in virulence among the isolates. Our results suggest that both seed and soil-borne inoculum may play a significant role in pathogen dispersal in the region. This is the first study on Rhizoctonia species and AGs in bean seed and soil in this region and it may contribute towards an efficient control strategy for bean diseases caused by Rhizoctonia species.
