A novel color-based recording and evaluation technique is presented which allows to determine the spatial distribution of foliage along approximately planar vine rows with high accuracy. The approach uses optical flow tracking to construct a composite from an image sequence and user-trainable bayesian color classification to segment foilage from a distinctively colored canvas carried along behi...

The main goal of this study was to determine the levels of knowledge of the farmers on the effect of pesticides on environment in Dawadmi Province, Saudi Arabia. This is achieved through realizing some secondary objectives such as identification of the farmers' socioeconomic characteristics and its relation to some of the study variables, their attitude towards the negative effects of pesticide...

BACKGROUND Leaf wall area (LWA) has been proposed as an appropriate dose expression for field testing of plant protection products (PPPs) applied via foliar spray in trellised grapes. However, its efficiency could change depending on the characteristics crop or pesticide application equipment (PAE). Herein, three technologies were evaluated. A traditional air-assisted tractor-mounted sprayer wa...

Mosquito control operators in France are mainly public and have at their disposal a wide range of spraying techniques to control mosquitoes. Due to the lack of commercial solutions, and in order to meet technical objectives and comply with regulations, they look to continuously improve their spraying application techniques. In the framework of the European Life+ project LIFE08 ENV/F/000488, the...
