Development of a situational on-farm stratgy to prevent carrot fly related damage in organic carrots
Project
Project code: 06OE095
Contract period: 01.05.2007
- 31.05.2010
Budget: 184,176 Euro
Purpose of research: Applied research
The carrot fly (Psila rosae) is one of the key insect pests in organic carrots (Daucus carota) throughout Germany. The project aims to develop a situational on-farm strategy based on preventative measures at farm planning level. Utilizing the prognosis model SWAT to forecast seasonality of carrot fly attack, which is developed by the Federal Biological Research Centre for Agriculture and Forestry, Germany, the project embarks on a coincidence avoidance strategy in time and in space, as a pest management tool. Milestones are the empiric appraisal of risk enhancing factors, quantifying namely a) cropping intensity, b) relative distance of carrot stands to hedges and tall vegetation, c) sowing and harvest date, maturity group, d) post harvest processing and treatment of carrot waste and soil material in relation to the seasonality of pest attack (1st and 2nd generation), continuously supported by the SWAT-Prognosis tool. Climatic- and GIS-supported spatial data on selected farms are gathered, accompanied by pest monitoring with standard yellow sticky traps and respective crop damage assessment in the field and at harvest. Based on these data, the project aims to develop a generalized preventative strategy, compromising potentially conflicting on farm production goals with pest management requirements. The joint project is accompanied by intensive field survey, on-farm trial work and extension activities.
