Project
Efficient innovative application techniques
New innovative application techniques can be used to significantly reduce the emission of crop protection agents. It may also be possible to reduce the amount of crop protection agents used as these new application techniques ensure a better and more uniform crop coverage.
The partners in this public-private collaboration are committed to developing new application techniques for fruit crops via crop-dependent spraying based on crop volume or crop row volume dosage. It is hoped that this will result in application techniques in the highest drift reduction class that produce an emission reduction of at least 95%.
These new techniques can significantly reduce emissions into the environment and the exposure of bystanders and local residents, while retaining a high level of biological effectiveness.
Goal
To develop application methods and calculation rules to ensure a uniform coverage of the crop to be sprayed depending on application technique and crop stage. The goal of reducing emissions by at least 95% will be achieved through a combination of technology and a decrease in the amount of agent used.
Approach
- Quantifying adjustable spraying technique parameters such as compressed air and variable spray volume on spray liquid distribution
- Quantifying spray liquid distribution in the crop and over the ground surface in and around the plot
- Developing calculation rules for use in practice
Results
- Efficient emission-limiting application techniques for crop protection agents suitable for >95% drift reduction
- Calculation rules for crop-dependent doses
