2.1. Data description

See sub-categories below.

2.1.1. Main characteristics of statistics

Since 2011, regular surveys of pesticides use have been carried out in Germany as PAPA surveys. PAPA stands for panel pesticide applications. A number of crop-specific networks of farms have been created, in which the PPP application data are recorded in detail annually. The data are forwarded in an anonymised form to the Julius Kühn-Institute (JKI).
The crops (winter wheat, winter barley, winter rape, corn, potatoes, sugar beets, apple, hops and vine) were selected for their relevance to the national action plan on the sustainable use of PPPs. This means, that the individual crop area is not the only important criterion for the selection, but also the intensity of chemical plant protection measures and the associated potential risk to human health and the environment.All surveys and analyses relate to the Federal Republic of Germany. The distribution of the panel farms was proportional to the distribution of arable land per crop.

2.2. Classification system

The classification used for pesticides corresponds to Annex III of Regulation (EC) No 1185/2009 (https://data.europa.eu/eli/reg/2009/1185/2017-03-09) of the European Parliament and of the Council.
The classification system for crops derives from the Annual crop statistics Handbook 2019 (https://ec.europa.eu/eurostat/cache/metadata/Annexes/apro_cp_esms_an1.pdf).

2.3. Coverage - sector

agriculture
The crops (winter wheat, winter barley, winter rape, corn, potatoes, sugar beets, apple, hops and vine) were selected for their relevance to the national action plan on the sustainable use of PPPs (NAP). This means, that the individual crop area is not the only important criterion for the selection, but also the intensity of chemical plant pro-tection measures and the associated potential risk to human health and the environment.

4.1.7. Additional comments quality assurance
4.2. Quality management - assessment

The distribution of panel farms (at least 100 farms per culture) is proportional to the distribution of the acreage of crops in Germany.
The documentation of the individual pesticide use data is done by the farmer himself. This data is then collected by regional staff and forwarded anonymously to the JKI. A data check (plausibility tests) is carried out by JKI. Missing or incorrect data is supplemented or corrected.  Standard statistical methods are used for the projections.
A comparison between pesticide application data and sales data gave satisfactory coincidence in the majority of cases. Unexplained deviations were only observed for active substances which are rarely applied.

5. Relevance Top
5.1. Relevance - User Needs

All groups in society (government agencies, non-governmental organizations, farmers' associations, etc.), who take part in the political debate on the use of plant protection products, are users of the data. In particular, the Federal Ministry of Food and Agriculture (BMEL) needs the results of the surveys in the framework of the National Action Plan on Sustainable Use of pesticides.
All relevant results are published on the website https://papa.julius-kuehn.de and in various publications.

 

5.1.1. Unmet user needs

Regional surveys are often requested. But the costs are too high.

 

5.1.2. Plans for satisfying unfilled user needs

No changes planned

5.1.3. Additional comments user needs

No other relevant information

5.2. Relevance - User Satisfaction

No activities

5.2.1. User satisfaction survey

5.3. Completeness

See sub-category below.

5.3.1. Data completeness - rate

Not applicable for Pesticide Use Statistics because in this data collection, there is no target on the number of data. Member States are asked to collect data on representative crops without stipulating the number of crops.


6. Accuracy and reliability Top
6.1. Accuracy - overall

see also Annex to concept 4.2.3:
The accuracy of the results of the statistical surveys is considered to be fully sufficient (especially from the perspective of current use). An improvement in accuracy can be achieved only by an extreme increase in sample size. The associated costs can not be justified.

6.1.1. Grading of accuracy
Moderate
6.1.2. Factors lowering accuracy
Other
6.1.3. Specification of factors

low sample size and agricultural diversity

6.1.4. Additional comments overall accuracy

No other relevant information

6.2. Sampling error

See the attached Excel file in the Annexes.

6.3. Non-sampling error

See sub-categories below.

6.3.1. Coverage error

See the attached Excel file in the Annexes.

6.3.2. Measurement error

See the attached Excel file in the Annexes:

No use of questionnaires. Use of original data from the farmers' records for PSM application. Documentation errors are usually detected directly when digitalising the survey data. The most common errors are incorrect or incomplete PPP-names and/or incorrect measurement units (e.g. kg/ha instead of g/ha). Missing data are supplemented; incorrect data are corrected.

6.3.3. Non response error

See the attached Excel file in the Annexes.

6.3.4. Processing error

See the attached Excel file in the Annexes.

6.3.5. Model assumption error

Not relevant, since only standard statistical methods are used for the projections.

 

6.4. Seasonal adjustment

Seasonal adjustment is not applicable to pesticide use statistics since all plant protection treatments associated directly or indirectly with the crop during the reference period are reported.

6.5. Data revision - policy

Our aim is: no revision!

6.6. Data revision - practice

In practice, there has been no revision of pesticide use data since 2011. If at any time published values need to be revised, this will be documented by a footnote.

8. Coherence and comparability Top
8.1. Comparability - geographical

It is assumed that the data is specific to Germany.

 

8.1.1. Asymmetry for mirror flow statistics - coefficient

Not applicable, because there are no mirror flows in Pesticide Use Statistics.

8.2. Comparability - over time

Not applicable for Pesticide Use Statistics, because it is not based on time series.

8.2.1. Length of comparable time series

Not applicable for Pesticide Use Statistics, because it is not based on time series.

8.3. Coherence - cross domain

The statistics on national PPP use are compatible to the statistics on the sales data, which is compiled by the Federal Office of Consumer Protection and Food Safety (BVL).

 

 

8.4. Coherence - sub annual and annual statistics

Not applicable for Pesticide Use Statistics, because the data collection is based on a five-year period.

8.5. Coherence - National Accounts

Not applicable, because it has no relevance for national accounts.
