This disc feature two new videos - Pythium Root Rot of Cereals and Rhizoctonia Root Rot of Cereals. 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.
5.1 Pythium Root Rot of Cereals
(10:00 min) Winner of 26th International Film Festival AGROFILM 1st Prize in the Category "Scientific and Popular Scientific Films"
Death of seedlings due to rotting of their roots is known as `damping-off'. This disease is usually caused by oomycetes in the genus Pythium, soilborne microorganisms related to brown algae. The circle of host plants parasitized by Pythium includes a wide variety of crops from virtually all climatic zones. By infecting germinating seeds and seedlings of all major grain crops, Pythium can cause significant losses in terms of quality and yield. Pythium root rot of cereals is so ubiquitous that it has been rightly called the `common cold' of cereals. This movie depicts the life cycle of Pythium using 3D computer animations blended with real images. Particularly, the formation and spread of motile zoospores is shown in detail. Finally, methods for successful disease management are explained.
5.2 Rhizoctonia Root Rot of Cereals
The fungus Rhizoctonia solani is a widespread inhabitant of soil. Hyphal anastomosis criteria are used to place isolates of Rhizoctonia solani into taxonomically distinct groups called `anastomosis groups'. Rhizoctonia solani strains classified in AG-8 are especially pathogenic to cereals, causing a root rot and stunting of wheat and barley plants, known as Rhizoctonia bare patch. The disease can be increased in direct-seed systems that lack tillage. The life cycle of Rhizoctonia solani is explained in clear, easy-to-understand 3D animations. The closely related fungus Rhizoctonia cerealis causing sharp eyespot of wheat is also described, followed by sequences focusing on disease management methods, including seed treatment.
