AI Technical Summary

Technical Problem

Existing chemical agents for controlling wheat stem rot have problems such as accumulation of pathogen resistance and pesticide residues, and there are no reports on the combination of existing microbial agents and chemical fungicides with Bacillus subtilis and magnolol, carvacrol, and eugenol.

Method used

Bacillus subtilis is compounded with magnolol, carvacrol or eugenol to form a composition of microbial agents and active enzymes, including active peptidase amino acid water-soluble fertilizer. The combined effect of the compound formula on the growth of wheat stem rot mycelium is determined by the indoor mycelium growth rate method to improve the prevention and control effect.

Benefits of technology

It enhances the control effect on wheat stem rot, reduces the dosage of pesticides, reduces pesticide residues, and improves the stress resistance and growth promotion of crops.

Abstract

The present invention belongs to the field of crop production technology, and specifically relates to a composition containing a microbial agent and an active enzyme. A microbial agent is prepared by compounding Bacillus subtilis with a bioactive bactericidal component; wherein the Bacillus subtilis is a Bacillus subtilis parent drug with a concentration of 500 billion cfu / gram; and the bioactive bactericidal component is selected from at least one of magnolol, carvacrol, and eugenol. The composition containing a microbial agent and an active enzyme of the present invention comprises a microbial agent component and an active enzyme component, wherein the microbial agent component exhibits a synergistic effect on inhibiting the mycelial growth of wheat stem rot fungi, can improve the control effect thereof, and is conducive to reducing the dosage of the agent, reducing the control cost and pesticide residue. In addition, the active enzyme component can improve the stress resistance of crops and promote crop growth.
