Objectives of the Course
The purpose of the course is to give the student a thorough understanding of the principles and methods of biological control of pests and diseases, provide knowledge of basic identification of biological control agents and help to understand relationships between pests and their natural enemies, observing the biocontrol mechanisms between the microorganisms in the ecological aspects, comprehend the obtain, bioformulation and application of the biocontrol agents, and to discuss some basic concepts and principles for preparing reseach project in .biological control of plant diseases.

Course Contents
Some basic concepts in biological control of plant dieases, examples of the plant diseases most favorable for biological control researh, planning surveys for collecting plant materials fom fiels, isolations of potantial antagonistic microorganisms, experimental proving some biological control mechanisms, tests for selection of potantial antagonists with the highest efficacy, in vitro tests, pot tests and field trials as in vivo tests. The final step of biocontrol studies is production of bio-formulations of effective antagonistic microorganisms against plant pathogens. This subject is broadly divided into six sections, covering characteristics of effective biocontrol organisms, genetic manipulations in order to improve the effectiveness of biocontrol organism, the process of the obtaining of bioformulations (substrate preparation and sterilization, fermentation, separation, formulation), formulation types (dry products, wettable powder and liquid formulations, granular formulations, bio-priming of the seeds), trends in formulation of microorganisms and future research requirements, the examples of commercial biocontrol products for use against plant pathogens.
