Designing permanent Agroforestry systems in emerging markets and developing countries. Developing concepts and farm plans.

Measuring plant density variation from aerial images should be possible to predict diseaseepidemics as plant density and disease severity are related. Fungicide application adjusted to plantdensities also could be challenged as it is not clear how crop density influence fungicide application effectiveness, there could be some dilution effect or lack of penetration. For better determination of timing for aerial images and effectiveness of this method in disease management more research needed. The experimental approach was chosen to clarify relationships between cereal crop canopy density, disease severity and fungicide application, and to assess if VRA map-based technologies have a potential practical use in disease management and yield prediction.
