Within the EU project ISAFRUIT (www.isqfruit.org) a Crop Adapted Application System (CASA) was developed to ensure precise, efficient and safe spray application in orchards, according to actual needs of the crop and with respect to the environment. The CASA system consists of three sub-systems: (i) Crop Health Sensor (CHS) iden­tifying heath status of fruit crops, (ii) Crop Identification System (CIS) identifying the tree canopy size and density, (iii) Environmentally Dependent Application System (EDAS) identifying environmental circumstances during spray applications. In order to protect sensitive areas within the orchards surroundings (e.g. surface water, melio­ration wells, public sites) the spray application parameters such as droplet size and air flow velocity need to be carefully adjusted taking into account wind direction and velocity as well as position of sprayer in relation to these areas. On EDAS sprayer wind velocity and direction is measured with an ultrasonic anemometer, and sprayer position is determined by GPS. Nozzles are altered automatically depending on wind situation to adjust droplet size according to drift risk level. A novel fan construction allows the supporting airflow to the left and right hand sections of the sprayer to be adjusted independently. This adjustment is done automatically depending on the wind situation and sprayer position.
EU "ISAFRUIT" Project covers different areas of research including investigation of effects of fruit consumption on well being, human health and obesity. Allergy induced by fruit consumption is also covered beside investigation of the risk to human health and environment of new methods of fruit production. Pillar covering fruit processing has been divided into 4 work packages (WP's), which share common idea of preservation in processed products, to the highest level possible, components beneficial for human health that are found in raw material. In the WP covering minimally processed fruit various techniques are applied including high pressure and microwaves to increase fruit safety. Direct juices, nectars and drinks are also object of research of this pillar as healthy products with high export potential. Selection of raw material for direct juice production and improvement of technology has been foreseen. The outcome of the project will also be new dried fruit products with functional properties. Proposal to utilize waste products (fruit pomaces) will also be given. Within the project several new approaches to fruit production methods and product management are developed, including Decision Support System, which will contribute to improvement of fruit quality supplied to the consumer. A new pesticide application system is under development, which will allow higher protection of environment. Beside applied research also basic research will be conducted within the project covering identification and mapping of the major genes responsible for fruit quality and development of safe and efficient transgenic techniques applicable to quality-fruit production. Knowledge created within the project will be disseminated using various tools such as internet, conferences, scientific publications and popular articles to inform European citizens. This should contribute, according to the project premises, to increased consumption of fruits and improvement of human well being and health.
