Chemical Control of Pests and Diseases in Forest Plantations
1 - Historical evolution from blind chemical control to Integrated Pest Management (IPM)
2 - Chemical Control: Principles and Practices
Definition and scope; Types of chemical control agents (fungicides, insecticides, herbicides, etc.); Formulations and application methods
3 - Pesticide Resistance and Environmental Impact
Mechanisms of resistance development; Case studies and statistics; Ecological and public health concerns
4 - Regulatory Framework
EU and Portuguese legislation (e.g., Dir. 2009/128/CE, Lei n.º 26/2013); Approval processes and safety standards; Sustainable Use of Plant Protection Products Regulation
5 - Product Composition and Classification
Active ingredients, adjuvants, synergists, co-formulants; Hazard classification and persistence; Selectivity and mode of action
6 - Application Technology
Types of applicators (manual, motorized, hydraulic, etc.); Calibration and safety procedures; Personal protective equipment (PPE)
7 - Decision-Making in Chemical Control
Risk assessment and product selection; Environmental considerations; Integrated decision-key approach
8 - Case Study: Fomes Root and Butt Rot of Conifers
Biology and impact of Heterobasidion annosum; Control options: stump treatment, species selection, no thinning; Remedial measures and site-specific strategies
Topics Covered:
An overview of the main pests affecting these forest species, their ecological and economic impacts, and the integrated management approaches being implemented.
