Abstract
The survey throughout major potato production regions indicated that A2 had been present in all provinces with various frequencies. Late blight breaks out usually most seriously where the weather is consistently cool and rainy. Under the conditions of diversified geographic and meteorological across China, the temperature and moisture may have different effect in various places. The preliminary-established gray Potato Late Blight-forecasting model for southern mountain regions of Ningxia could be used as a routine predication for late blight. Some clones with horizontal resistance have been screened out after being evaluated for a few years. In Hebei and Inner Mongolia, some major cultivars in production contain horizontal resistance to late blight. Recent year's genetic engineering on potato late blight was also conducted in China. Tests in both lab and fields indicated that metalaxyl resistant isolates appeared and the effectiveness of metalaxyl on late blight disease were weakened. However, the Ridomil MZ 58 WP still hold high control effect. A new fungicide named Flumborph was synthesized in recent years in China. It shows very good systemic and protective control effect on late blight. A significant progress has been made on using ferment liquid from Xenorhabdus nematophilus in both lab antagonize test and greenhouse field control trials. Some suggestions presented in the workshop are related to research aspects below: eradication of pathogen in diseased tubers and oospores in the soil; monitoring the chemical resistant isolates; short-term disease forecast; disease epidemic pattern in double-cropping region; formation of a national or regional late blight forecast center.
