“…It was determined that the PGPR applications could be able to increase plant growth, germination rate of seed, improve transplant emergence, response to stress conditions and protect from disease (Elkinci et al 2014), such as Azospirillum, Pseudomonas and Azotobacter have significant impact on seed germination and transplant growth (Shaukat et al 2006a, b, Nezarat andGholami 2009). Application of strains BSCBE4 and PA23 at the rate of 20 g kg -1 of seed significantly increased the growth of hot pepper seedling (Nakkeeran et al 2006). According to Kokalis-Burelle et al (2003) PGPR could be used to obtain standard sized transplant in less time and a more vigorous transplant for transplant production.…”

Abstract. Yanti Y, Astuti FF, Habazar T, Nasution CR. 2017. Screening of rhizobacteria from rhizosphere of healthy chili to control bacterial wilt disease and to promote growth and yield of chili. Biodiversitas 18: 1-9. Bacterial wilt on chili cause by Ralstonia solanacearum. This disease is important, causing plant death and significant yield losses. Biological control is desirable because control with other methods gives variable results. One of the important group of biological agent is the plant growth promoting rhizobacteria (PGPR). This group can control plant pathogens and enhance the growth and yield through direct and indirect mechanisms. The aim of this research was to obtain indigenous rhizobacterial isolates from rhizosphere of healthy chili, which are effective to control bacterial wilt disease and to promote plant growth as well as to increase plant yields. The rhizobacterial isolates were collected from healthy chili rhizosphere in endemic area of bacterial wilt at Banuhampu Sub-district, Agam District, West Sumatra, Indonesia. Screening method of rhizobacterial isolates to control bacterial wilt was based on in planta technique. This technique was consist of three steps, as follow: (i) Screening of 43 rhizobacterial isolates to induce the hypersensitive reaction on Mirabilis jalapa. (ii) Screening of 42 rhizobacterial isolates (from first step) to increase growth of chili seedlings and (iii) Screening of 20 selected rhizobacterial isolates (from second step) to control bacterial wilt on chili. R. solanacearum were inoculated on the 6 weeks chili plants using Two strains of rhizobacterial isolates from chili rhizosphere (RZ.2.1.AG1 and RZ.1.3.AP1) showed high potential for disease suppression and also increased growth and yield of chili.

“…In several studies, the quantification of activity of enzymes involved in the induction of resistance has been used as a parameter to assess the induction mechanism (biotic or abiotic) involved (Knorzera et al 1999;Campos et al 2004;Nakkeeran et al 2006;Silva et al 2004;Halfeld-Vieira et al 2006;Saikia et al 2006). The increase in activity and accumulation of these enzymes depend mainly on the inducing agent but also the genotype of the plant, physiological conditions, and the pathogen (Tuzun 2001).…”

“…From earthworm's intestine, new Streptomyces isolate has been reported which showed antimicrobial activity against pathogenic fungi and bacteria (Aruna et al 2008) and also few Actinomycetes isolates with chitinase and proteinase activity (Gopalakrishnan et al 2011), and the presence of these biological factors in liquid products derived from the VC invariably has an important role in enzyme degradation of root-knot nematode cuticle and the egg wall. Azotobacteria as well as Pseudomonases have been reported in these compounds (Nakkeeran et al 2006) and these bacteria producing various metabolites inhibit nematode egg hatching (Sikora and Hoffmann-Hergarten 1993). In total, earthworm products are the very active biological compounds of bacteria and enzymes and can be considered as nematode ovicidal as well as larvicidal factors, and at the same time there are some other unknown factors which need to be explored.…”

Background Biocontrol of nematode agents to decrease the hazardous impacts of chemical pesticide application including problems of public health and environmental pollution is a priority. In this study, solid (Vermicompost) and liquid products (Liquid Vermicompost, Vermiwash and Coelomic fluid) of the earthworm species Eisenia fetida were tested against root-knot nematode, Meloidogyne javanica in vitro and greenhouse conditions. Results Results showed that Liquid Vermicompost, Coelomic fluid and Vermiwash had the greatest effect on egg hatching inhibition, respectively, and Coelomic fluid, Vermiwash and Liquid Vermicompost had the highest effect on mortality of larvae (J 2 ), respectively, in vitro. All earthworm-based products were added to the cucumber pots and then a root-knot disease as well as plant growth indices was recorded. Results showed that all products could reduce the number of nematode juveniles and gall index in greenhouse conditions. The best combination for controlling disease was Vermicompost ? 10 % Liquid Vermicompost and the highest rates of growth related to plants were treated with Vermicompost ? 10 % Vermiwash.Conclusions It is concluded that earthworm products have a remarkable potential as control agents against rootknot nematode and improving host plant health.
