How does a microbial agent with dual effects of fertilizer and medicine help crops resist disease?
In recent years, the damage of soil-borne diseases to crops has become more and more serious, seriously affecting the quality of agricultural products and food safety. The microbial agent that arises at the historic moment can cut off the infection of soil-borne diseases from the root, so how does it do it?
??
1. Maintain the balance of microflora:
Due to the long-term cultivation of cultivated land in China, the pathogenic bacteria in the soil are dominant, and soil-borne diseases are rampant. Microbial agents contain a large number of highly active beneficial bacteria, which can greatly increase the content of beneficial bacteria in soil, maintain the balance of microbial flora, and thus inhibit the infection of soil-borne diseases.
??
2. Promote the growth of crops:
In addition to some nutrient elements needed for crop growth, microbial agents can also activate the nutrient elements fixed in the soil, provide nutrients for plants, make crops grow more robust and naturally have a stronger ability to resist diseases.
3. Secrete bacteriostatic substances:
Some beneficial microorganisms themselves have antagonism to harmful bacteria, or can secrete antibiotics to inhibit the reproduction and growth of pathogenic bacteria, so as to reduce the occurrence of diseases and insect pests.

4. Improve crop resistance to stress:
Some beneficial microorganisms can improve the drought resistance, salt-alkali resistance, extreme temperature, humidity and pH resistance of crops, and metal toxicity, which greatly increase the resistance of plants to these stress conditions.
5. Stimulate crops to produce beneficial ingredients:
After the use of microbial agents, crops can promote the production of chitinase, glucanase and other system defense enzymes and bacteriostatic substances, so as to improve crop disease resistance and promote crop growth.
