Abstract

The invention discloses a pine endosymbiotic bacterium which is classified and named after a new burkholderia cenocepacia NSM-05 and is stored in the China typical culture collection center with the storage number of CCTCC NO: M2011015 and the storage data of January 11, 2011. The invention also discloses application of the new burkholderia cenocepacia NSM-05 to the preventing and treating pine shoot dieback diseases and promoting the growth of pines. The invention also discloses an antagonistic inoculant for preventing and treating the pine shoot dieback diseases; the antagonistic inoculant is obtained by inoculating NSM-05 bacterium strains in a culture medium. The NSM-05 bacterium strain provided by the invention is the pine endosymbiotic bacterium, has strong bacteriostasis on the pine shoot dieback diseases, has the antagonism effect on multiple woods and crop pathogenic bacteria and road-spectrum antibacterial activity, is safe and non-toxic to people, livestock and plants and has good development and application prospects.

Description

technical field

[0001] The invention relates to endophytic bacteria of plants, in particular to a pine endophytic bacterium Burkholderia neocepacia NSM-05 and application thereof. Background technique

[0002] Pine dieback (Sphaeropsis sapinea) is one of the most common and widely distributed diseases of coniferous trees worldwide. Among the nearly 30 countries where the disease is distributed in the world, the most affected countries are: New Zealand, Australia, South Africa, the Netherlands, the United States and China. It has a very wide host range and can infect Pinus L., Abies Mill, Larix Mill, Thuja L., Cedrus Trew, More than 60 kinds of coniferous trees belonging to 8 genera including Juniperus L., Picea Dietr. and Pseudotsuga Carr. Although the host range of the pathogen of pine dieback is wide, the susceptibility of different hosts is different. Currently, only slash pine, loblolly pine, masson pine and sylvestris pine are known to cause economic losses. Since 19...
