INTERNATIONAL COOPERATION IN VIRUS RESEARCH ON ORNAMENTAL PLANTS

H. Ronde Kristensen
The International Society for Horticultural Science (ISHS) is a world-wide organization that deals with all aspects of horticultural sciences. Following a proposal from Professor Broadbent from Great Britain, the ISHS-Council decided to establish a Plant Protection Commission so that plant protection could be an integral part of the work of the Society. In his proposal Professor Broadbent stated "that even if the plant pathologists should some day set up a separate international body, there would still be many aspects of the subject peculiar to horticulture". The Plant Protection Commission held its first meetings in 1966 under the chairmanship of Professor Broadbent and with Mr. Leister of Great Britain as secretary. When Professor Broadbent in 1970 wanted to resign as chairman, he was followed by the present chairman, Professor ten Houten from The Netherlands. Since 1968 I have been secretary of the commission and have been vice-chairman since 1970.

The main object of the commission is to encourage international cooperation regarding measures against plant diseases and pests in horticultural crops. In order to accomplish this important task in the best possible way, several working groups have been established. It might here be stressed that the general policy of the Plant Protection Commission is to avoid any overlapping of work. Therefore, we are very anxious not to establish any working group on subjects which are adequately covered by existing groups.

Since the establishment of the plant protection commission, a new big society "has been born", namely the International Society for Plant Pathology (ISPP). The Plant Protection Commission wishes to have the closest possible cooperation with this society, and this has so far been easily accomplished since the chairman of our commission, Professor ten Houten, is also secretary-general of ISPP. It is generally agreed that the ISPP should take care of the more pathogen-orientated working groups, while the crop-orientated groups should be placed under the ISHS.

At present the Plant Protection Commission has established six working groups dealing with:

  1. Virus diseases of ornamental plants,
  2. Soil-borne pests and pathogens of horticultural plants,
  3. Bacterial diseases of horticultural plants,
  4. Virus diseases of vegetables,
  5. Aphid pests of horticultural plants,
  6. Weed control in vegetables.

Furthermore, negotiations are currently in progress regarding establishment of a new group to deal with resistance breeding in horticultural crops. The first working group established within the Plant Protection
