The invention provides a
beauveria bassiana application method for plane farmland crops. The
beauveria bassiana application method is suitable for spraying
powder in a large-area, small-size and high-density
crop planting farmland area, and since a hose can be horizontally spanned above a planting compartment surface after being inflated,
beauveria bassiana
spore powder can be directly sprayed to most farmland areas by utilizing an existing field road; the conditions that the manual spraying range is small, the mechanical spraying cost is high, bacterial liquid is not prone to covering the whole
plant, and
allergy is prone to occurring in manual
powder spraying at present can be effectively overcome, the using effect of
beauveria bassiana is effectively guaranteed, and a
beauveria bassiana air
sowing material is sprayed out through an air outlet blowing
sowing opening in the hose after being fully mixed with high-pressure air in a hard
pipe; in the application process, when
beauveria bassiana spores are sprayed to the crops, all spaces of the whole growth area of the crops can be completely and uniformly covered, leakage of the area covered by the beauveria bassiana
spore powder and concentration of the powder are avoided, the first-time insecticidal effect is guaranteed, and then the reproducibility of the beauveria bassiana is more effectively guaranteed.
