“…In the current study, majority of the endophytic strains of Bacillus species dwelling inside pearl millet host revealed their antifungal potentialities towards three agriculturally important plant pathogens (RS, SR, and FS). These fungal pathogens are preferred as test organisms for antagonistic confrontation assay due to their wide host range, prolific growth, and ability to cause major economic loss in various crops [60][61][62]. Further, in India, wilt and root rot caused by FS, is a major disease of pearl millet that significantly reduces production, and causes severe yield losses under congenial environmental conditions [63].…”

Plant growth promoting and antifungal activity in endophytic Bacillus strains from pearl millet (Pennisetum glaucum)

Bacterial endophytes are well known inhabitants of living plant system and perform important assignments in maintaining plant growth and health. Currently, limited reports are available on the endophytes of pearl millet (Pennisetum glaucum) reflecting antagonistic and plant growth promoting (PGP) attributes. Therefore, the major objectives of current investigation were to identify antagonistic strains of endophytic Bacillus from pearl millet and further illustrate their PGP capabilities. In this study, 19 endophytic Bacillus strains (EPP5,

“…Several attempts had been made by researchers to identify nontoxic chemicals especially from natural sources like botanical extracts, which are cheaper alternatives to control fungal diseases in plants . Seed treatment of sorghum with aqueous extract of Eclipta alba had been reported to markedly reduce seed infection by Curvularia , Fusarium , and Phoma species . However, attempts to discover natural fungicides against sorghum grain mold from plants are hardly found in the existing literature.…”

In this study, investigation was carried out under in vitro as well as field conditions to explore inhibitors of sorghum grain mold. Phytochemicals, viz., methyl trans-p-coumarate (AIC-1), methyl caffeate (AIC-2), syringic acid (AIC-3), and ursolic acid (UA), at different concentrations (500, 750, and 1000 ppm) were tested on spore germination of Alternaria alternata, Curvularia lunata, Fusarium moniliforme, F. pallidoroseum, and Helminthosporium sp. Significant growth inhibition (P < 0.001) was observed against all fungi except A. alternata which was found to be resistant to AIC-3. Further, two separate sets of field experiments involving spraying of water and F. moniliforme suspension over chemicals treated (1000 ppm) sorghum panicles were done. The levels of protection varied with different treatments which were graded using a standard 1 - 9 rating scale. The Fusarium-challenged panicles (FCP) showed lesser susceptibility and decreased the rate of infection of grain mold (grade 7.0), compared to simple UA, AIC-2, and AIC-1 treatments (7.4, 7.6, and 8.0 grade, resp.). The HPLC quantification of differentially induced phenolic acids in treated sorghum grains substantiated this effect disclosing the higher accumulation of chlorogenic, vanillic, and salicylic acids in FCP. This might be due to defensive induction of these acids by the plants. Although mold control by examined chemicals were lesser than the standard Tilt (grade 5.9), they were found to be nontoxic to mammalian cells under cytotoxicity assay.

“…In addition, the work of [10] on fungi isolated from groundnuts in Benin showed the antifungal activity of essential oils and aqueous extracts of O. americanum on several toxigenic strains of the genus Aspergillus and Fusarium. The work of [11] demonstrated the efficacy of C. schoenanthus essential oils against sorghum and millet seed-borne fungi. The work of [12] carried out on the seeds of some cereals such as maize in the presence of phytopathogenic and toxinogenic fungi in Togo showed that the essential oils of O. basilicum and C. schoenanthus have antifungal activity by improving the germination rate of the seeds of these two crops.…”

Rice is one of the most widely produced cereals in Burkina Faso. However, the fungi transmitted by rice seeds, Oryza sativa L, cause enormous production losses in rice fields. The aim of this study was to assess the efficacy of powdery formulations of essential oils against Magnaporthe oryzae in rice. Thus, rice seeds of the FKR64 variety were disinfected with 15% sodium hypochlorite for 10 minutes and soaked in the suspension of 104 conidia/ml for 24 hours. These contaminated rice seeds were coated into powdery formulations of essential oils of L. multiflora, C. schoenanthus and their combination at a dose of 10g/kg of seed. A contaminated control was used. The experimental set-up was a completely randomised block with four treatments in three replicates, one of which was an absolute control. These treatments were carried out on L. multiflora essential oil, C. schoenanthus essential oil and their combination at a proportion of 50%. The results showed that the essential oil of L. multiflora recorded the highest percentage emergence, average height and average number of tillers of the plants, with values of 97.33%, 47.67 cm and 7.89 tillers respectively. This same formulation recorded the lowest percentage of seedling melt and foliar incidence, at 1.33% and 11.67% respectively. These essential oil formulations can be recommended for seed treatment against Magnaporthe oryzae.
