INTERNATIONAL COOPERATION IN VIRUS RESEARCH ON ORNAMENTAL PLANTS
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:
- Virus diseases of ornamental plants,
- Soil-borne pests and pathogens of horticultural plants,
- Bacterial diseases of horticultural plants,
- Virus diseases of vegetables,
- Aphid pests of horticultural plants,
- 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
