2. Statistical presentation Top
2.1. Data description

The survey takes into consideration all enterprises which distribute pesticides in Italy, for each province,  either under their own brand or foreign brands. The main variables surveyed are:  quantity of pesticide product and quantity of the active substances (produced in Italy or imported)  distributed with own trademark for only agricultural use, for each province.  When the pesticides are imported, the enterprise can state the pesticides distributed with other trademark (if they haven’t their appropriate trademark).
The reference period is calendar year (2016).

The term pesticide indicates those products containing or comprised of substances intended for various uses, including protecting plants or plant products from harmful organisms, destroying unwanted plants or parts of plants. The term active substances refers to all substances which exert a general or specific action against harmful organisms or on plants or parts of them.

Phenomena investigated are:  - sale of pesticides, per category (fungicide, insecticide and acaricides, herbicide, biological, other and insect traps), toxicity class and province (Nuts III level); - sale of the active substances authorised for the market.

Biological products and traps were introduced in the survey, in order to complete the survey

3. Statistical processing Top
3.1. Source data
Pesticides for each enterprise which distribute pesticides in Italy for agricultural use,  either under their own brand or foreign brands.
3.2. Frequency of data collection
Frequency is annual. Reference period is calendar year.
3.3. Data collection
Self-administered data collection - via electronic transmission through the upload of excel file on Istat web site (INDATA through Business Portal)
3.4. Data validation

Data are validated to the following actions:
Coherence control with data from other surveys or sources (the results are compared with similar results obtained in other processes of the Institute, or with datafrom external sources, for example specialized magazines)

3.5. Data compilation

After the collection of the questionnaires, there is a first phase of  check: 
If it is possible, the questionnaires of an enterprise are compared with data of the previous year.
If an error occurs, the enterprise is contacted by  phone to confirm or not the new data.

The phase of editing data is done comparing data at level of each active substance. Imputation of missing value (total non response, or partial non resposonse) are carried out with metodological statistical model.   


Interactive correction of errors on the base of deterministic rules or on the base of data stemming from previous survey's edition.

3.6. Adjustment

4. Quality management Top
4.1. Quality assurance
Since the 90s Istat adopted a systematic approach to ensure quality in both statistical information and service to the community. For this purpose the Institute has defined a quality policy providing itself with appropriate tools as well as management changes to carry it out. Istat quality policy is coherent with the European framework developed by Eurostat, taking up its main principles and definitions. In 2005, the European Statistics Code of Practice (revised in 2011 and in 2017) established the principles to follow in order to ensure and strengthen both accountability and governance of the European Statistical System and the National Statistical Systems inside it.
Essential points of Istat quality policy are:
  • Process quality: consisting in the production of accurate statistical information efficiently and effectively;
  • Product quality: consisting in the dissemination of high-quality timely statistical data which are relevant for the users, also the potential ones;
  • Documentation: consisting in the storage and availability of information necessary not only for a proper use of data but also to ensure transparency in all the production activities of statistical data;
  • Respect for respondents: consisting in the reduction of response burden and in the respect of respondent's privacy;
  • Strengthening of statistical literacy: consisting in promoting a proper use of statistical information in policy-making to better support decisions and policies;
  • Users' orientation: consisting in making statistical information easily accessible and understandable and in satisfying user needs as much as possible.

4.2. Quality management - assessment

Surveys on sales have been conducted in Istat for several years and the content is very detailed in terms of information on pesticides and in terms of geographical detail.

The survey is included in the National Statistical Programme. It is a census based survey conducted every year.


5. Relevance Top
5.1. Relevance - User Needs

Main data users: Ministry of Agriculture, Ministry of Heath, The Institute for Environmental Protection and Research, ISPRA (Istituto Superiore per la Protezione e la Ricerca Ambientale). For example, ISPRA uses the data to produce the national report on the presence of pesticides in water that provides information on on the risks due ti the presence of these substances in water.

11. Confidentiality Top
11.1. Confidentiality - policy

Several national legal acts guarantee the confidentiality of data requested for statistical purposes. According to art. 9, paragraph 1 of the Legislative Decree n. 322 of 1989, personal data cannot be disseminated but in aggregated form, in order to make it impossible to make any reference to identifiable individuals. They can only be used for statistical purposes. Legislative Decree n. 322 of 1989, art. 6 bis and Legislative Decree n. 196 of 2003 Annex A3 (Code of conduct and professional practice applying to the processing of personal data for statistical and scientific research purposes within the framework of the national statistical system), art. 8, provide that the exchange of personal data within the National Statistical System (Sistan) is possible if it is necessary to fulfil requirements provided by the National Statistical Programme or to allow the pursuit of institutional purposes. The supply of the identification data of statistical units is allowed within the framework of entities included in the National Statistical System if the requesting party declares that no identical statistical result can be obtained otherwise . Regarding subjects who do not belong to Sistan, Article. 7 of the Code of conduct (Decree n. 196/2003, Annex A3) states that it is possible to transmit individual data files without direct identifiers within the framework of specific laboratories set up by entities included in the National Statistical System, under certain conditions and only if that the data are protected by the application of different statistical methods that make it highly unlikely the identification of statistical units.

11.2. Confidentiality - data treatment

During the phase of data treatment, the confidentality is assured by different storage of two different datasets: one contain the microdata with identification code of enterprise, and second dataset contain the  identification code and the address of enterprise.
Threshold rule applied to data transmitted to Eurostat: active substances distributed by less then 3 enterprises are flagged as confidential.
