Setaria bipolaris strain and use for preventing and killing off weed

Abstract

The invention relate to a new bacterial strain NY1 of setaria bipolaris strain, which is stored in the China General Microbiological Culture Collection Center since April 1st, 2009 with the preserving number of CGMCC No.2989. The herbicidal combination comprising the said bacterial strain NY1 and the carrier commonly used in the pesticide field can be used for preventing and killing off Gramineae weed such as setaria, Chloris virgata, crab grass, goosegrass herb, barnyard grass and the like, preferably for preventing and killing off setaria, Chloris virgata, crab grass. The inventive bacterial strain and the herbicidal combination can be used for preventing and killing off Gramineae weed in the agricultural land and garden of non-corn and planting area, preferably in the broad-leaved crops.
