Evaluation of biocontrol preparation and plant extracts for the control of Phytophthora infestans on potato leaves. Stephan, D., Schmitt, A., Carvalho, S.Microbial enrichment to enhance the disease suppressive activity of compost. Annual report Late Blight New Development 9-13 pp Changes in frequencies and distribution of A2 mating types and metalaxyl-resistant isolates of Phytophthora infestans in Korea. Mating type and metalaxyl sensitivity of Phytophthora infestans isolated from Gangwon area in Korea. The resistance clone named as 'Haryeong' is considered suitable for organic potato cultivation in Gangwon province in Korea. Contrarily, disease incidence of the susceptible variety was 100% and the AUDPC was 1773.5 during the same cultivation period. The area under disease progress curve(AUDPC) was 75.5. Disease incidence was 2.3% using the resistant clone. However, one clone is resistant in organic farming fields. The number of sporangia ranged from $10^sporangia/ml$ in the susceptible clones at 7 days after inoculation. Dominant isolates of the pathogen in Gangwon province produced abundant sporangia on leaves of most clones showing susceptibility. Resistance of the clone was examined through artificial inoculation in the laboratory and in the field. Since the cultivation of resistance cultivar is essential for organic agriculture, Phytophthora late blight resistance of 16 advanced potato clones obtained from the potato breeding laboratory at the National Institute of Highland Agriculture was evaluated. ![]() (Crop Research Division, National Institute of Highland Agriculture, RDA) (Organic Farming Technology Division, National Institute of Agricultural Science and Technology, RDA) ![]()
