Abstract:

A three-year study on the control efficacy of pine wilt disease using four different methods: removal of infected trees, removal of infected trees combined with crown spraying, removal of infected trees combined with trunk injection, and removal of infected trees combined with both trunk injection and crown spraying was conducted. The results showed that the control methods for pine wilt disease, removal of infected trees alone achieved a control efficacy of 60.94%. Adding crown spraying to infected tree removal increased the efficacy to 64.21%. Incorporating trunk injection alongside infected tree removal yielded a control efficacy of 71.73%, while combining infected tree removal with both trunk injection and crown spraying achieved the highest efficacy of 73.75%.

Key words: pine wilt disease, control methods, control efficacy
