Pine wilt disease damage has been spreading nationwide, surpassing 4 million trees in the past five years, but despite large-scale budget allocations, the control results have not been significant. According to the "Status of Pine Wilt Disease Occurrence in the Recent 5 Years (2021-2025)" submitted to the National Assembly's Agriculture, Forestry, Fisheries, and Food Committee by Kim Seon-gyo, a People Power Party member (Gyeonggi Yeoju-Yangpyeong), the number of damaged trees has increased sharply from 307,919 trees in 2021 to 1,065,967 trees in 2023, and then to 1,486,338 trees in 2025. The cumulative damage over five years reaches 4,137,320 trees. In particular, in 2025, despite the related budget being expanded to 100 billion won, the number of damaged trees increased significantly compared to the previous year, raising questions about the effectiveness of the control measures. By region, North Gyeongsang Province recorded the highest damage with 1,865,147 trees, followed by South Gyeongsang Province (898,168 trees), Ulsan (354,924 trees), national forests managed by the Korea Forest Service (317,524 trees), Daegu (186,733 trees), and Gyeonggi Province (143,845 trees). The areas affected by the pine wilt disease are also steadily expanding. The number of cities, counties, and districts where pine wilt disease has occurred increased from 131 in 2021 to 154 in 2025, and the "extremely severe areas" with the most serious damage increased from zero to six areas, including Ulsan Ulju, North Gyeongsang Province's Pohang, Gyeongju, Andong, South Gyeongsang Province's Milyang, and Changnyeong. Kim Seon-gyo emphasized, "In the situation where pine wilt disease is spreading nationwide, despite the increase in budget, the control results are insufficient," and "We need to thoroughly re-examine the effectiveness relative to the budget and establish stronger control measures." Meanwhile, the Korea Forest Service plans to improve its control policies in response to the spread of pine wilt disease. The agency intends to revise the system to allow the removal of damaged trees during non-control periods if there is a risk of disaster, and to revise the related control guidelines by the end of this month. Lee Yong-kwon, the Korea Forest Service's Forest Disaster Control Director, stated, "We will continue to improve the policies by reflecting the voices from the field to achieve results in controlling pine wilt disease."
