Abstract
The present invention belongs to the technical field of maize disease control methods, and particularly relates to a biological bactericide for controlling maize ear rot, its preparation method and application. The biological bactericide comprises a water dispersible granule carrier mixture and a biocontrol bacteria culture solution, and the mass ratio of the water dispersible granule carrier mixture to the biocontrol bacteria culture solution is 2-3:1; the water dispersible granule carrier mixture comprises diatomaceous earth, chitosan and sucrose, and the mass ratio of diatomaceous earth, chitosan and sucrose is 1-2:1-2:1; the biocontrol bacteria culture solution is obtained by mixing fermentation broths of Bacillus subtilis, Streptomyces microflavus, Paenibacillus polymyxa and Bacillus velezensis. The biocontrol bactericide provided by the present invention has a very significant effect on controlling maize ear rot caused by Fusarium verticillioides, has the potential to be used as a new biological pesticide for controlling ear rot caused by Fusarium verticillioides in maize production, and has the value of further research.
