Abstract

The application discloses a method for controlling ear diseases and pests of corn by using insecticidal diatomaceous earth, green muscadine and wood fungus in combination; the insecticidal diatomaceous earth, the dispersible oil suspension agent of the green muscadine beetle CQMa421 and / or the spore suspension of the echinoporus GDFS1009 are combined to be sprayed on the body of the corn borer larvae or the ears or leaves infected by the corn borer and the ear rot fungus, the control effect on the corn borer reaches 60-80%, and the control effect on the ear rot caused by the pseudorhizomycete fusarium reaches 60-100%. It is found that the control effects on the corn borer larvae and the ear rot are obviously higher than those of the same amount of single preparation, the synergistic green prevention and control of the ear corn borer and the ear rot is realized, and it is a new green prevention and control technology for the ear diseases and pests of corn.
