The Nature and Practice of Biological Control of Plant Pathogens (Φύση και πρακτική του βιολογικού ελέγχου των παθογόνων των φυτών - έκδοση στα αγγλικά)

The Nature and Practice of Biological Control of Plant Pathogens

 
Examines the broad subject of biological control of plant pathogens in a unified framework of concepts and principles. Among the principal themes is the fact that slight changes in an environmental factor often produce striking effects in plant-microbe interactions.
