Leaves infected by Phytophthora infestans were collected from potato fields in southern Norway in the growing season of 2000 and 2001. Oospores were found in 8 out of 9 fields, in different cultivars and in unsprayed and sprayed fields. Oospores containing leafdiscs were buried in soil under field conditions in 1998 and tested for viability. There was no decline in viability between burial for 20 and 31 months.

Five compost samples from organic household waste were analysed for suppression of damping-off caused by Pythium ultimum and Rhizoctonia solani on cucumber. Four of the samples were in some degree suppressive to P.ultimum. No one of the samples were suppressive to R. solani.

In 2001, a zone site C, was established as a circular areas with 50 km radius and centred in Greåker close to Sarpsborg in South-eastern Norway. Zone site C is complementary to the similar zone sites A and B established in 2000. From June 2001 to December 2002, 601 wood samples were collected from 66 forest blocks, all situated within the 3 existing zone sites A, B and C. The sampling was carried out in the provinces Akershus, Buskerud, Vestfold and Østfold, but was concentrated to the South-eastern region, where 399 samples were taken from 45 forest blocks in the province of Østfold. Samples from Scots pine (Pinus sylvestris) formed 96% of the collected material, while Norway spruce (Picea abies) was a minor fraction. Lying trees and various kinds of detached wood formed the main part of the objects sampled. The frequency of objects showing signs of attack by wood boring insects was 44%. Some samples were also taken in Porsgrunn in the province of Telemark from a consignment of spruce imported from Russia. Nematodes were often more common in samples from objects with signs of insect activity. In four samples, all from lying pine trees, nematodes belonging to the genus Bursaphelenchus were detected. Bursaphelenchus mucronatus was recorded for the second time in Norway, and occurred in a lying pine tree attacked by Monochamus at Ombudstvedt in the municipality of Våler in the province of Østfold. The pine wood nematode Bursaphelenchus xylophilus was not detected, nor in forests or in 5 samples from spruce imported from Russia

For å finna ut korleis kavlitet og avling vert påverka av direkte såing, og planting etter ein forkultur i kålrot, vart det i åra 1999-2001 prøvd ulike sortar på tre stader.

Såing ga samlet best kvalitet på røttene. Ved å regulere planteavstand/tynningsavstand i kålrot kan en bestemme ønsket vekt på røttene.
