Deuteromycotina: Fusarium, Cercospora, Colletotrichum.
Mushroom cultivation: Mycorrhizal application in agriculture and forestry;
Fungal cytology and genetics: Heterothallism, heterokaryosis, parasexual cycle, mutation.
UNIT IV
Symptomatology in fungal, bacterial and viral infection of plants
Etiology and control of the following crop diseases
1. Paddy: paddy blast, paddy blight
2. Wheat: Black stem rust, Bunt of wheat
3. Bajara: green ear and Ergot
4. Sugarcane: Red rot disease of sugarcane.
5. Ground nut: Tikka disease
6. Maize Smut
UNIT V
Role of enzyme and toxins in pathogenesis;
Disease control by physical, chemical and biological methods, resistant varieties;
Crop rotation, plant quarantines, seed certification
PRACTICAL 102:
Study of the morphological characters and reproductive structures of the genera mentioned in the theory. Study of symptomatology of diseased species. Carbon and nitrogen utilization by fungi (in culture) vitamin requirement, staining techniques for cytological studies, induction and isolation of mutants.
1. Study of diseased specimens of plants with reference to symptomatology.
2. Isolation, purification and single spore culture of pathogens.
3. Measurement of the activity of enzymes of fungal pathogens: Cellulose, Pectinases.
4. Laboratory testing of fungicides (systemic and non-systemic) against pathogenic fungi.
5. Demonstration of biological control of pathogenic fungi in vitro.
