THE INTEGRATED FRUIT PRODUCTION IN THE REGION LAKE CONSTANCE

The following features are first results of the research project: "Environmental safe production of vegetables and fruit". In this project German and Swiss scientists work together.
To combine theory and practice, a working group with 8 German and 8 Swiss fruit growers was established.

The aims are:

• to describe the production (area, kind of production, input factors etc.) and

• to analyse the environmental impact of the production in a second part (1996–98).

Pomefruit is the main fruit with nearly 9000 ha (96% apples). IFP reached an extend of 90% in the German and 81% in the Swiss part.
According to the working group the German growers need 5.3 h and the Swiss growers 2.6 h per ha and year for the orchard control.
In the average in the German/Swiss part fungicides are applied 14.6/13.4, insecticides 3.9/3.5, acaricides 1.1/0.6 and herbicides 2.6/2.1 times per year.
In the Swiss part with a total of 696 h, 197 h (40%) more labour is done per ha and year than in the German part.
