Abstract:
Conclusion of the control experiment: <br/>
-Spraying with Combo is the most efficient, low cost- and least manpower-requiring treatment. <br/>
-On the other hand, the commonly used concentrations of this herbicide resulted in high mortality rates of all other components of the vegetation.<br/>
-Half of the application rate of Combo in combination with cutting reduces the impact on other vegetation dramatically, but is still highly efficient with respect to bracken.<br/>
-Black-foil & cutting, or cutting alone proved as the best method for bracken control if herbicides are not allowed and other vegetation should be preserved.
Additional Infos:
Treatments:<br/>
Asulam with 400g/l active agent: 6l/ha<br/>
Glyphosat with 480g/l active agent: 4l/ha<br/>
Wilt Pruf with 25% active agent in solution: 6l/ha<br/>
Combo (PM) with 240g/l Picloram and Metsulfuron Methyl (60% p/p): 4l/ha<br/>
black foil: 6x6m/Plot<br/>
transparent foil: 6x6m/Plot<br/>
Cutting: only bracken leaves were cut, other vegetation remained in the plots<br/>
treatment combinations:<br/>
all treatments mentioned above were used in combination with cutting in alternating application<br/>

Date monthly (YYYY-MM-01)
Description
:
Date of a month (the day is not relevant and set by default to the 1st of the month). The format is YYYY-MM-01.
This format can be used to indicate that values have been aggergated (average, sum, mean, etc) over a month. More details of the aggregation method are annotated in method steps of the individual attribute or in the title or abstract of the dataset.
This format can also be used to indicate that only the month of an event is known. More infromation have to be added to the dataset description.
