| 摘 要： | 在松萎蔫病是由松材线虫与其携带的致病细菌诱导的一种复合侵染病害的新学说的指导下,根据松萎蔫病在疫区病树呈聚集分布,提出了防治松萎蔫病的新策略,即利用我们研究开发防治松萎蔫病的新药剂α-三噻吩与杀细菌剂恶喹酸对在以病死树中心周围半径50 m的范围内所有寄主树进行注干处理。经过2010—2011年在面积近20 hm2的处理黑松林地的防治试验,至2011年12月已经取得了良好的防效。处理林地中没有再发生病死树,对照区内却有24株病死树。防治仍在继续,新结果将继续报道。 |

| Abstract: | On the basis of the new theory,namely that the pine wilt disease is a complex one induced by the pine wood nematode and its associated pathogenic bacteria,and that the special pattern of pine wilt disease in a forest belongs to agg-regated distribution,we suggest a new strategy,that is to treat all of the host trees by trunk injecting of the new nematicide,α-terthienyl and a bactericide,oxolinic acid,within the area bounded by a circle of 50m radius and the concentration point of the dead trees as the center of the circle.The new strategy had been used in a 20hm2 forest of Pinus thunbergii during 2010 to 2011.Up to now there has not been any dead tree found in the treated area in contrast to 24 dead ones in the control area.The test in the forest is continuing and new results will be followed. |
| Keywords: | to eradicate pine wilt disease bactericide α-terthienyl control effect |
