Bio-priming Seed Treatment for Biological Control of Pythium ultimum Preemergence Damping-off in sh2 Sweet Corn

Connotation of Enterobacter cloacae-W6 and Serratia ficaria-W10 with or without carriers for improving growth, yield and nutrition of wheat

“…Soaking of the seed with PGPR broth accelerate physiological changes for ultimate germination (Anitha et al, 2013) and increase beneficial microbe number in spermosphere (Taylor and Harman, 1990). Higher numbers in the spermosphere benefit the germinated plants to gain vigor and better defense against diseases, improve plant growth leading to higher crop yield (Callan et al, 1990). Peat is the best carrier as compared to press mud and biogas slurry as it provides nutrition, surface area and moisture to inoculated microbes.…”

Enhanced Sweet Corn Propagation: Studies on Transplanting Feasibility and Seed Priming

“…The mechanisms employed by Trichoderma species to affect disease control includes mycoparasitism and antibiotic (toxin) production, competition through rhizosphere competence, production of enzymes such as chitinases and glucanases responsible for the suppression of plant pathogen by destroying cell wall integrity, induction of defense response in plant such as peroxidase activity (Harman 2000, Harman et al 2008, Howell 2003. The biological seed treatments have been reported as an effective seed protection method in sweet corn using Trichoderma (Bjorkman et al 1998, Bjorkman 2004, Harman et al 1989, Parera & Cantliffe 1990), Pseudomonas (Callan et al 1990, Cantliffe & Bieniek 1988, Mathre et al 1995, Gliocladium (Hartz & Caprile 1995).…”

Biopriming of Chickpea Seeds with Biocontrol Agents for Enhanced Seedling Vigour and Reduced Seed Borne Diseases

“…Among the seven treatments tested for their efficacy in the management of seed-borne infection of chickpea seeds of variety JG -11, the treatment P. fluorescens @ 0.8 % + T. harzianum@ 0.8 % + Vermiculite shown the least per cent seed infection of 13.00, highest per cent seed germination of 91.00 and vigour index of 1753.13 which was statistically superior over other treatments (Table 1) This difference is due to the vermiculite holds the moisture and provides when seed needs it during biopriming and also biocontrol agent may multiply substantially on seed during biopriming (Callan et al, 1990). The present findings are in agreement with Harman et al, (1989) reported that in field trial stands of peas were not significantly enhanced by seed treatment with T. harzianum strains in the absence of priming but were improved by T. harzianum + vermiculite.…”
