In-depth understanding of the conditions under which pathogens, in particular parasitic fungi, live and develop is a prerequisite for effective crop protection.
The DVD series The Biology of Fungal Pathogens grants easy access to this knowledge. Through an exciting blend of vivid three-dimensional animations and real images, with informative commentaries, these videos provide fascinating insight into the life cycles of major fungal pathogens. The series is an outstanding example of communication in modern science.
Videos on this DVD:
4.1 Eyespot Disease of Small Grains (13:00 min)
(Winner of the 2006 Scientific and Popular Scientific Films)
Where small grains are grown continuously and the climate is cool and moist, eyespot disease, also called strawbreaker foot rot, is a significant yield-limiting disease. This infection of the stem base is caused by fungi of the genus Helgardia (formerly Pseudocercosporella): Helgardia herpotrichoides (teleomorph Oculimacula yallundae) and Helgardia acuformis (teleomorph Oculimacula acuformis). Both species differ in terms of morphology and growth characteristics. This movie depicts the life cycles of both species using three-dimensional computer animations blended with real images. Particularly, the modes of infection as well as epidemiological spread of the disease are shown. Finally, methods for successful disease management are explained.
4.2 Bunt and Smut Diseases of Cereals (10:00 min)
Common bunt of wheat caused by Tilletia caries and loose smut of barley caused by Ustilago nuda are cereal diseases that have been increasingly forgotten as a result of modern seed treatments. However, when untreated seed is used, infection by these damaging fungal pathogens can lead to substantial losses in yield and seed quality. Using Tilletia caries and Ustilago nuda as examples, this movie illustrates the life cycles of bunt and smut fungi with extensive detail, thus leading to a better understanding of the development and epidemiological spread of these fascinating fungi. All stages of the life cycles are explained using photolike three-dimensional computer animations, macro images, and real-image video sequences.
