Abstract

The invention discloses a compound biopesticide for preventing and curing a rice sheath blight disease and a preparation method thereof. The pesticide can improve the soil fertilizer efficiency at the same time and is a biopesticide with the effects of both a fertilizer and a pesticide. The pesticide is an aqueous solution or powder, the active ingredients in the aqueous solution or powder comprise bacillus subtilis B-2103 and paecilomyces lilacinus BS-003, and the weight ratio of the bacillus subtilis B-2103 to the bacterial strain of the paecilomyces lilacinus BS-003 is 1:(0.0005-1000). The bacillus subtilis B-2103 to the bacterial strain of the paecilomyces lilacinus BS-003 are compounded, the extracellular metabolite has an excellent effect of preventing the rice sheath blight disease and nitrobacteria, the bacterial strain of the paecilomyces lilacinus BS-003 play the synergistic effect, so that the rate of preventing and curing the rice sheath blight disease is more than 82%, meanwhile, the fertilizer efficiency of the soil is improved, and the utilization efficiency of the soil fertilizer N is strengthened.

Description

technical field [0001] The invention relates to a biological pesticide and a preparation method thereof, in particular to a compound biological pesticide for preventing and treating rice sheath blight and a preparation method thereof. Background technique [0002] Rice sheath blight is one of the three major diseases of rice. It is widely distributed in the world and is very harmful. This disease not only affects the yield of rice, but also seriously affects the quality of rice. So far, the disease has generally occurred in rice-growing countries in Asia, America, and Africa, and some control measures have been taken for rice sheath blight. Consult related documents, Chinese Patent Publication (Announcement) No.: CN103396954A, discloses a kind of biological control bacterial strain for preventing and controlling rice sheath blight, biological organic fertilizer and preparation method thereof, utilizes Trichoderma aculeatus strain 12 fermented liquid to prepare a biological ...
