Pesticide use, 2011

Only statistics for the whole country.

Every second or third year.

Eurostat

A data file with anonymous individual data is stored at Statistics Norway.

The purpose of the survey, which is partly financed by the Norwegian Ministry of Agriculture and Food, is to shed light on pesticide use in agriculture.

 The survey results serve as input to national authorities when monitoring and assessing health and environmental hazards of pesticide use.

The first survey of pesticide usage on arable crops was carried out for 2001, whereas the first on greenhouses was carried out for 2008.

Public administration and research institutions within agriculture and the environmental sector as well as professional organizations in agriculture.

The survey are based on "Guidelines for the Collection of Pesticide Usage Statistics within Agriculture and Horticulture" and A common methodology for the collection of pesticide usage statistics within agriculture and horticulture; issued by Eurostat.

Voluntary survey.

REGULATION (EC) No 1185/2009 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 25 November 2009 concerning statistics on pesticides.

The survey of pesticide use in greenhouse production comprises the following crops: cut flowers, flowering potted plants, bedding plants, decorative plants, lettuce, herbs, tomatoes and cucumbers.

The survey of pesticide usage on arable crops comprises the following crops: potatoes, onions, common cabbage, carrots, strawberries, apples, meadows and pastureland, barley, oats, spring wheat, winter wheat and oil-seeds. These crops comprised about 96 per cent of total agricultural area in use. The basic population for the survey was holdings applying for governmental subsidies as per 31 July. Holdings with mainly organic production or holdings under conversion to organic production were omitted.

Most of the data have been gathered via a questionnaire-based sample study. Area data from a survey concerning yield of crops in horticulture were used as frame for ornamental plants, lettuce, herbs, tomatoes, cucumbers, onions, common cabbage and carrots. For other crops, area data from the application for governmental subsidies were used as frame. Area data from these data sources were also used when presenting results from the survey.

The gross sample for the survey of pesticide usage in greenhouse production included 405 holdings in 2015. It was voluntary to respond the questionnaire. Nevertheless, the survey got a response rate of 84 per cent.

The gross sample for the survey of pesticide usage on arable crops included 4 234 holdings in 2014. It was voluntary to respond the questionnaire. The survey as a whole had a response rate of 59 per cent.

The sample for the survey of pesticide usage on arable crops was drawn in three steps:

• In step 1, the crops were ranged from the crop with fewest holdings to the crop with most holdings.
• In step 2 a measure for expected total use of pesticides per holding was estimated. Within each crop this load was proportionally distributed according to agricultural area of the holding (4 classes). The number of units in each sub-sample (crop) were proportionally distributed according to this distribution.
• In step 3 the holdings within each area class were sorted by number of crops and load before drawing the sample.

Data for the survey of pesticide use in greenhouse production was collected electronically. The questionnaire was made available to the respondents in January. Two written reminders were sent. The questionnaires were registered and then edited with aid of a computerized error-detection program.

Data for the survey of pesticide usage on arable crops was collected via a questionnaire distributed by mail to the person who according to the application for production subsidies was holder of the holding. The questionnaire was mailed to the respondents in December. One written reminder was sent.

The questionnaires were registered, optically scanned and then edited with aid of a computerized error-detection program. Data from applications for agricultural production subsidies were used during the control.

Concerning the survey of pesticide usage on arable crops the holdings in the population and in the sample were stratified by agricultural area in use (4 classes) and area of the surveyed crop (2-4 classes). The estimated weights had to give the correct number of holdings by agricultural area in use and by area of the surveyed crop. Furthermore, the weights had to give the correct area of the surveyed crops by the same stratification.

The holdings in the sample and in the population were stratified by utilized agricultural area (4 classes) and area of surveyed crops (2-4 classes). The estimated weights should give the correct number of holdings by utilized agricultural area and by area of the surveyed crops. Furthermore, the estimated weights should give the correct area of the surveyed crops by the same classification.

All results of a sample survey have a certain sampling error. The sampling error has been assessed by means of the number of observations and the coefficient of variation (VAR). The presentation of results is based on the following guidelines:

Figures with greater VAR and/or based on fewer observations than described above are not presented and are thus indicated as colon (:). However, the guidelines have been derogated in a few cases where the VAR are just over the limits and there are quite many observations.

The first survey of pesticide use in greenhouse production was carried out in 2008. The surveys conducted in 2012 and 2015 had different methodology and the results are not directly comparable.

Surveys using the same methodology concerning pesticide usage on arable crops in Norway were carried out in 2001, 2003, 2005, 2008, 2011 and 2014.
