Syllabus
Prerequisites: Biology, General and Inorganic Chemistry, General Principles of Agronomy, Crop Production
Target skills and knowledge: The aim of the course is:
a) knowing weeds from the biological and ecological point of view, their effect on the human activity, in particular about agriculture, and their role in the agroecosystem, b) knowing the weed control methods, both chemicals and non-chemicals, c) learning to plan control systems less expensive and safer for the environment, d) knowing the mitigation measures to reduce the contamination of surface and depth waters.
Examination methods: Open questions and numeric execises
Assessment criteria: Knowledge of the subject; clear exposition of the subject; correct scientific speech
Course unit contents: 1° credit
Definition of weed, and biological, ecological and botanical classification of weeds.
2° credit
Practical lessons: identification of the weeds at various phenological phases (seedling and vegetative stage)

3° credit
Weeds as persistent component of the agroecosystem: ecological and agronomic significance of dormancy, real and potential flora, seed dynamics in the soil. Practical lessons: methods used to break seed dormancy (stratification, scarification ), and methods for evaluation of the soil seed bank.
4° credit
Weeds as dynamic component of the agroecosystem: intraspecific evolution of weeds and resistance phenomena; weeds evolution at the community level, compensation phenomena and introduction of exotic species. Practical lessons: numeric exercises on indexes of diversity and transformation of weed community
5° credit
Weeds as damaging component of the agroecosystem: allelopathy, competition, competition related to weed density and time of weed-crop interference.
6° credit
Integrated weed management system: weed management based on actions on crop and weed community.
Principles of integrated weed control: economic-threshold based control, density equivalent concept, decision support system, scouting. Practical lessons: scouting in field, practice lesson on Gestinf, numeric exercises on economic thresholds.
7° credit
Herbicide-plant interactions: absorption, translocation, biotransformation, mode of action, HRAC classification, selectivity. Practical lessons: determination of leaf wettability, characterization of the epicuticular waxes, classification of herbicides based on the phytotoxic reaction of the plants.
8° credit
Herbicide resistant crops, environmental fate of herbicides, mitigation measures of drift, runoff and leaching
Planned learning activities and teaching methods: The course includes lectures, practical exercises, and visit to crop fields for identification of the weeds at various phenological phases (seedling and vegetative stage).
