PGPR mediated management of stem blight ofPhyllanthus amarus(Schum and Thonn) caused byCorynespora cassiicola(Berk and Curt) Wei

EvaluatingPseudomonas aeruginosaas plant growth-promoting rhizobacteria in West Africa

“…Public concern over pollution, as well as pathogen resistance to some pesticides, have intensified the need to find alternative methods for stimulating plant growth and for protection against crop diseases (Dal-Bello et al 2002). Environmentally friendly microorganisms have proved useful in plant growth promotion, disease control and pest management (da Luz et al 1998;Weller 1988;Kloepper et al 2001;Kravchenko et al 2002;Mathiyazhagan et al 2004) and they represent a promising solution in overcoming the problems of disequilibrum in natural balance usually associated with chemical methods (da Luz 2001). Although bacterial cultures (both live and dead) have been widely studied and used in developed countries with evidence of good support to agriculture (Ryder et al 1999;Timmusk et al 1999), nothing similar has been reported on the west coast of Africa.…”

Detection of antibiotic-related genes from bacterial biocontrol agents with polymerase chain reaction

“…Three Bacillus strains were also effective against the wheat head blight pathogen Fusarium graminearum in planta (Fernando et al 2002). Pseudomonas chlororaphis PA23 has been shown to inhibit several root pathogens in greenhouse and field experiments (Kavitha et al 2005;Mathiyazhagan et al 2004). The presence of a well-defined zone of inhibition of fungal growth on plates by all eight strains suggests that antibiosis is likely an important mechanism involved in antifungal activity and disease suppression.…”

Biocontrol of <I>Rhizoctonia solani</I> Root Rot of Chilli by <I>Bacillus subtilis</I> formulations under Pot Conditions

“…consortia in Talc reported considerable control in rice sheath blight and enhancement in plant yield when compared to single strains under field conditions (Nandakumar et al, 2001). Talc and peat based formulations of P. chlororaphis and B. subtilis have exhibited similar results in the control of turmeric rhizome rot (Mathiyazhagan et al, 2004). The work of Salaheddin et al, (2010) revealed a reduction in population level in talc formulation of B. subtilis after 60 days of storage.…”

“…Soil application of different species of Bacillus was attempted by Lamsal et al (2012) and a 40% reduction in anthracnose incidence was achieved which was lower by 10% according to the values obtained in the present study. Efficient reduction in the stem blight of Phyllanthus amarus was achieved by root dip treatment of seedlings with talc-based formulation of B. subtilis (BSCBE4) or Pseudomonas chlororaphis (PA23) (Mathiyazhagan et al, 2004). Combined seed application of B. subtilis CA32 and Trichoderma harzianum RU01A brought about a 50% reduction in Fusarium wilt disease incidence as reported by Abeysinghe (2007).…”
