Abstract

The invention discloses a compound of a Paenibacillus polymyxa and a validamycin used for controlling a rice sheath blight disease and is characterized in that the invention is a pesticide compound formed by mixing the Paenibacillus polymyxa and the validamycin with a weight percentage that the Paenibacillus polymyxa to the validamycin is equal to 1: 0.01 to 100; a formulation of the invention can be processed into water aqua, powder or suspending agent. As the mechanisms of action of the two biological pesticides are not the same, the invention draws the strong points to offset the weak points through a mode of mixing and preparing according to a certain proportion and is used for controlling the rice sheath blight disease which can exert cooperative actions of the two, improve the controlling effect and greatly reduce the dosage and retard the fastness of harmful bacteria.

Description

technical field [0001] The invention belongs to pesticide preparations, in particular to a composition of Paenibacillus polymyxa and Jinggangmycin for preventing and treating rice sheath blight. Background technique [0002] Paenibacillus polymyxa is a microbial pesticide, and its insecticidal mechanism is the broad-spectrum antibacterial substances produced by it, site competition and induced resistance to achieve disease control effects; currently it is mainly used in production to control ginger blast. Jinggangmycin is a water-soluble antibiotic produced by the strain of Streptomyces hygroscopicus Jinggang. When the rice sheath blight mycelia come into contact with Jinggangmycin, it can be quickly absorbed by the bacteria and conducted in the bacteria, interfering with and inhibiting the bacteria The cells grow and develop normally, thus playing a therapeutic role; however, Jinggangmycin has been used to prevent and control rice sheath blight for 30 years, and it is very ...
