Learning Objectives
Basic knowledge of plant pathology, of the biology of the main disease agents and of the control methods. To be able to identify the main grapevine diseases and to set up adequate control strategies
Prerequisites
Courses recommended: Grapevine biology, Microbiology, General viticulture
Teaching Methods
Lessons in the class-room, seminars by experts and technical personnel in the plant protection sector and vineyard management, observation of symptomatic samples of grapevine in the lab
Further information
Frequency of lectures, seminars and practice: not compulsory but strongly recommended
Type of Assessment
Written exam for the general part (3 cfu), oral exam for the specialistic part (6cfu). Only the ones that passed the exam on the general part will be admitted to the second oral part of the exam.
Course program
DETAILED PROGRAMME (3 cfu):
Historical hints. Concepts of disease, pathogenicity, virulence, resistance, susceptibility. Kock’s postulates.
Taxonomy and structure of fungi, bacteria and viruses. Symptoms, principles and procedures for a diagnosis. Disease cycle, infection process and influencing factors. Principles of epidemiology.
DETAILED PROGRAMME GRAPEVINE DISEASES (6 cfu):
Abiotic diseases: Main abiotic diseases of grapevine. Means and methods of control: principles: prevention, curative control, resistance, biological control, integrated control and chemical control. Integrated pest management, sustainable disease control and main european and national regulations. Nazianla plan for the sustainable use of pesticides (PAN). Main characteristics of the main tools available in grapevine disease prevention and control: biological tools, biostimulants, and alternatives in general. Main characteristics of the active substances usable on grapevine, resistance to fungicides, certified propagation material.
Fungal diseases. Cycle, biology, main fungicides, control strategy of downy mildew, powdery mildew, grey mould, sour rot, black rot, white rot, main wood diseases (esca, grapevine leaf stripe disease, wood cankers, excoriose). Root rot by Armillaria and Rosellinia, black foot. Prokariots: crown gall, Xylophilus ampelina, yellow diseases (flavescence dorée, bois noir). Viral diseases: transmission and infection process in viral diseases, leaf roll, fanleaf, infective spotting, vein necrosis. Lab work. Procedure for a diagnosis, description of symptoms in infected samples. Surveys in grape-growing farms: fungicide storing, management of control plans, “quaderno di campagna”, disease symptoms in the field.
