The increase in the world population has generated an important need for both quality and quantity agricultural products, which led to a significant surge use of chemical pesticides fight crop diseases. Consumers, however, have become very concerned recent years over side effects fungicides on human health environment. As result, research into alternative solutions protect crops been imposed attracted wide attention from researchers worldwide. Among these alternatives, biological controls through beneficial microorganisms gained considerable importance, whilst several control agents (BCAs) screened, among them Bacillus, Pantoea, Streptomyces, Trichoderma, Clonostachys, Pseudomonas, Burkholderia, certain yeasts. At present, biopesticide products developed marketed either leaf diseases, root or fruit storage However, no positive correlation observed between number screened BCAs available products. Therefore, this review emphasizes development biofungicides screening marketing problems that hinder their development.
