“…T. harzianum is well known biocontrol agents against several soil borne pathogens. Osman et al (2011) showed that, T. harzianum was found effective in inhibiting the R. solani causing soya beans root rot. In the present study, T. viride was found to be effective among the other antagonists.…”

“…Thus, Pseudomonas strain WPS3 was found more effective in controlling the root rot disease caused by R. solani. Different microbial antagonists have been found to control the root rot caused by Rhizoctonia solani in different crops [45,46]. Similarly, inoculation with P. aeruginosa and B. subtilis was found to significantly suppress root rot infection under green house as well as field conditions and enhanced the plant growth and yield in moongbean, wheat and maize [8].…”

Pathogenic fungus Rhizoctonia solani causes root rot disease in wheat leading to collapsing of the aerial part of the plant. To characterize antagonistic bacteria, one hundred and thirty bacterial isolates were obtained from the rhizosphere soil of wheat and these rhizobacterial isolates alongwith 72 reference strains were screened for their antagonistic interactions against R. solani under cultural conditions. Sixteen bacterial isolates inhibited the growth of R. solani and growth inhibition zone varied from 6-15 mm by different rhizobacterial isolates. Two isolates WPS3 and WPS90 caused maximum growth inhibition of the fungi. Growth inhibiton of the pathogenic fungi was also observed using culture filterates of antagonistic rhizobacterial isolates. The protein estimation of the culture filterates showed that the amount of protein excreted by different rhizobacterial isolates varied from 3.6 to 33.0 mg ml -1 of the supernatant. The loss of antagonistic activity after treatment with proteinase K and high temperature treatment indicated that excreted proteins are responsible for the antagonism. Pot house studies showed that inoculation of R. solani in wheat caused 85-90% root rot disease incidence at 60 to 90 days of plant growth. The single inoculation of rhizobacterial isolate WPS3 resulted in 131% increase of plant dry weight as compared to uninoculated control plants. The coinoculation of isolate WPS3 with R. solani enhanced 115% plant dry weight whereas coinoculation of Pseudomonas isolate WPS90 caused 98% increase in plant dry weight in comparison to control uninoculated plants at 90 days of plant growth. Coinoculation of Pseudomonas isolates WPS3 and WPS90 with R. solani also caused 88.9 and 66.7% disease control, respectively at 90 days of plant growth. Thus, Pseudomonas isolate WPS3 could be further exploited for plant growth improvement under field conditions.

“…Among Nostocales, methanol extracts from Nostoc spp. were efficient in reducing the colony growth of the fungi Armillaria sp., Rosellinia sp., Sclerotinia sclerotiorum, Penicillium expansum, Verticillium albo-atrum, and R. solani and of the oomycetes Phytophthora cambivora and P. cinnamomi [102,106]. Rhizoctonia solani and the oomycete Pythium debaryanum were also inhibited by Anabaena variabilis and A. oscillarioides culture filtrates and leachates from compost amended with each cyanobacterium viable cells [21].…”

Cyanobacteria, also called blue-green algae, are a group of prokaryotic microorganisms largely distributed in both terrestrial and aquatic environments. They produce a wide range of bioactive compounds that are mostly used in cosmetics, animal feed and human food, nutraceutical and pharmaceutical industries, and the production of biofuels. Nowadays, the research concerning the use of cyanobacteria in agriculture has pointed out their potential as biofertilizers and as a source of bioactive compounds, such as phycobiliproteins, for plant pathogen control and as inducers of plant systemic resistance. The use of alternative products in place of synthetic ones for plant disease control is also encouraged by European Directive 2009/128/EC. The present up-to-date review gives an overall view of the recent results on the use of cyanobacteria for both their bioprotective effect against fungal and oomycete phytopathogens and their plant biostimulant properties. We highlight the need for considering several factors for a proper and sustainable management of agricultural crops, ranging from the mechanisms by which cyanobacteria reduce plant diseases and modulate plant resistance to the enhancement of plant growth.
