چکیده

Compost tea has a lot of potential for sustainable agriculture. The suppressive effect compost on damping-off disease in beans (Phaseolus vulgaris), caused by Rhizoctonia solani, was investigated. physicochemical properties the tested showed presence dissolved solids (7070 mgL-1), organic matter (1280 nitrate (3840 and ammonium (90.0 mgL-1). concentrations phosphorus, potassium, calcium, magnesium were 22.7, 1540, 214, 2.40 mgL-1, respectively. highest inhibition R. solani growth at concentration 30% filtrate 87.0% it completely inhibited 50%. application or chemical fungicide (Rizolex-T) significantly decreased pre- post-emergence enhanced plants survival. In spite total phenol content bean infected with (15.6 µg·g-1 fresh weight), treatment using Rizolex-T further elevation content, to 17.5 14.7 weight, These findings support use as alternative synthetic fungicides help achieve environmental sustainability food safety farming.

Compost Tea as a Container Medium Drench for Suppressing Seedling Damping-Off Caused by Pythium ultimum.

ABSTRACT Compost tea is being used increasingly in agricultural production to control plant diseases. However, there has been limited investigation relating disease control efficacy to various compost tea production methods, particularly compost tea produced with active aeration and additives to increase microbial population densities in compost tea. Aerated compost tea (ACT) and nonaerated com...

Liquid culture production of microsclerotia and submerged conidia by Trichoderma harzianum active against damping-off disease caused by Rhizoctonia solani.

Media and culturing protocols were identified that supported the formation of submerged conidia and microsclerotia (MS) by Trichoderma harzianum Rifai strain T-22 using liquid culture fermentation. Liquid media with a higher carbon concentration (36 g L(-1)) promoted MS formation at all C:N ratios tested. Hyphae aggregated to form MS after 2 d growth and after 7 d MS were fully melanized. This ...

competition for iron uptake by fluorescent pseudomonads to control of rhizoctonia solani kuhn causing agent of bean damping-off disease

abstract fluorescens pseudomonads can suppress soil-borne plant pathogens by employing several mechanisms such as competition for iron by means of siderophores. three indigenous strains pseudomonas fluorescens (utpf5, utpf61 and utpf76), pseudomonas aeruginosa 7nsk2 and its pyoverdin mutant, mpfm1, were used for investigation the effect of iron competition on bean damping-off suppression. the r...
