The average annual yield loss caused by late blight was huge, accounting for 63.54% of potato yield losses caused by all diseases. Among the four farming regions, the northern region had the largest annual occurrence acreage of about 73.44×104 hm2, and the southwestern region had the highest average annual yield loss of about 14.29×104 tons. The distribution of late blight occurrence changed in a similar trend to that of the potato planting areas. The susceptible varieties Favorite as a representative, were still planted in a large area across the country, but in recent years, some resistant varieties have been planted with an increasing area. The control of late blight in China has been greatly improved in recent years, but it still relied too much on chemical application. Therefore, the application of green control technologies should be strengthened. keywords:potato late blight  potato farming region  spatial-temporal characteristics  occurrence  control View Full Text  View/Add Comment  Download reader
