34th Meeting on the Working Party on Plant Protection Products

Bishkek, 2004-05-18/20



The 34th Meeting of the Working Party on Plant Protection Products took place in Bishkek on 18-20 May 2004, at the kind invitation of the Kyrgyz Department for Plant Protection and Ministry of Agriculture, Water Resources and Processing Industry.


There were 20 participants from 12 EPPO countries and ECPA.


Our hosts gave us a warm welcome, provided excellent facilities for the meeting and organized very interesting technical visits. It was a marvellous experience for all participants to see the natural beauties of this mountainous country (ninety percent of the country’s area is over 1300 m in elevation) and to learn about their agriculture and plant protection. Although only 7% of the Kyrgyz Republic’s land is arable, the most important sector of its economy is agriculture. About 30% of people are directly dependent upon agriculture. The main crops are wheat, barley, maize, potatoes, melons, oilseed crops, sugar beet, fodder crops, vegetables of many kinds, cotton and tobacco.


The Working Party reviewed the work of the Panels placed under its authority, directed their future work and made a number of recommendations to EPPO Council. Some of the major points of decisions and recommendations are summarized here.

Programme of activity

The Working Party re-considered its future activities with the possible expansion into other areas of plant protection. The following important topics were discussed: mutual recognition of the data, comparability of efficacy evaluation data with emphasis on comparable climates, problems with resistance, minor use problems, database on uses of plant protection products, ecological farming. The Working Party decided that an ad hoc Panel should be created to set a scope of a database on uses of plant protection products.
