Beauveria bassiana application method for plane farmland crops

Abstract

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.

Description

technical field [0001] The invention relates to a pesticide application method, in particular to a Beauveria bassiana application method for planar farmland crops. Background technique [0002] Beauveria bassiana is one of the high-efficiency broad-spectrum parasitic microbial insecticides. Beauveria bassiana colonies are white powder, and the product is white or off-white powder. Its insecticidal active substance is the living spores of Beauveria bassiana. After the spores contact the pests, they germinate under suitable temperature conditions, and the growing mycelium invades the insects, producing a large number of mycelia and secretions, making the pests sick and dying after about 4-5 days. The dead worm body is white and stiff, and the body surface is covered with hyphae and white powdery spores. It is an effective biological pesticide for the biological control of leaf-eating pests in agriculture and forestry. It has the advantages of no pesticide residues, no resi...

AI Technical Summary

Problems solved by technology

[0007] At present, the commonly used dusting machines are mostly operated by a single person, and the spraying range is small, so it is difficult to cover a large area of ​​farmland; Higher facility requirements and higher costs

In addition, the side branch leaves at the bottom of the crops are easily blocked by the side branch leaves at the top, so the atomized Beauveria bassiana liquid sprayed from the nozzle of the special sprayer cannot effectively cover the side branch leaves at the bottom of the crop, thus affecting the killing effect
