  author={Lalehan Yolageldi and G. Turhan},
The goals of the present study were to determine ifCylindrocarpon olidum var.olidum exerts antibiotic activity on teliospore germination ofTilletia laevis in vitro and to evaluate the efficacy of a seed treatment with this antagonist against artificial seedborne infection in the field under natural cropping conditions. Germination of bunt teliospores was completely inhibitedin vitro on water agar medium supplemented with the antagonist’s culture filtrate. In field experiments seed application…

The Biological Control Possibilities of Seed-Borne Fungi
This chapter summarizes the results of experiments conducted in pot and field conditions applying useful microorganisms to seeds naturally or artificially infested with pathogens, and provides an outlook for future research.
Mechanisms of Action of Fungal Biological Control Agents
Determination of the modes of action of fungal BCAs will be useful to develop appropriate application methods for effective management of crop diseases.


Inhibition of Tilletia laevis teliospore germination and suppression of common bunt of wheat by Pseudomonas fluorescens 2-79
A rifampicin-resistant derivative of Pseudomonas fluorescens strain 2-79 (Pf2-79r) inhibited teliospore germination of Tilletia laevis and afforded no protection against common bunt.
Biological Control of Common Bunt (Tilletia tritici)
The present study indicates that biological control can be successfully used without negative effects on seed germination and vigor and a combination of biocontrol agents and milk powder improves the efficacy of biOControl.
Biological control of common bunt (Tilletia tritici) in organic farming
Current study indicate that biological control can give successful control without negative effects on seed germination vigour, and a combination of biocontrol agents and milk powder improves the effect of the biOControl.
Biological control of cereal seed-borne diseases by seed bacterization with greenhouse-selected bacteria
One Pseudomonas isolate, MA 342, strongly and reliably suppressed both D. teres and T. caries in the field, while effects against M. nivale were weaker and could not be enhanced by varying pre-application or seed application procedures.
Effect of seed treatment with acetic acid in control of seed borne diseases
In field trials, seed treatment with acetic acid has reduced common bunt in winter wheat by 91.5-96.2% and by 83% in spring wheat without negative effects on germination vigour of the seeds.
Suppression of take-all of wheat by seed treatments with fluorescent pseudomonads.
Howell and three, or possibly more consecutive crops of wheat after alfalfa or Stipanovic (7,8) demonstrated that strains of Pseudomonas potatoes, to help eliminate soilborne pathogens of those crops.
Performance of the Pseudomonas chlororaphis biocontrol agent MA 342 against cereal seed-borne diseases in field experiments
The bacterial biocontrol agent Pseudomonas chlororaphis, strain MA 342, was tested for activity against a number of cereal seed-borne diseases in a total of 105 field experiments carried out at
Organic Seed-treatment as a Substitute for Chemical Seed-treatment to Control Common Bunt of Wheat
Investigation of alternative control measures to chemical seed-treatments that are environmentally friendly to support cultivar resistance showed that skimmed milk powder, hucket, and wheat flour reduced common bunt infection levels by 96%, 93% and 62%, respectively.
Effect of seed treatment with milk powder and mustard flour in control of common bunt (Tilletia tritici) in wheat and stem smut (Urocystis occulta) in rye
In field trials mustard flour was able to control seed borne infection by common bunt by coating the seeds with milk powder without decreasing the germination vigour of the treated seeds.
Selection of biological control agents for controlling soil and seed-borne diseases in the field
The shortcomings of laboratory methods focused on mechanism of action are discussed and it is concluded that these methods should be used with caution if candidates with multifactorial or plant mediated mechanisms of control are to be obtained.
