Streptomyces
Product Overview
Streptomyces are beneficial actinomycetes widely used in agricultural production. Jinrun Bio manufactures high-activity, high-purity microbial inoculants including Streptomyces rimosus and Streptomyces microflavus. The strains feature stable reproduction and are independent functional strains with great application value, each with its own emphasis on biocontrol, soil improvement and crop growth promotion. Such microbial agents must not be mixed with high-concentration fungicides and should be stored in cool and dry places.
表格
| Comparison Items | Streptomyces rimosus | Streptomyces microflavus |
|---|---|---|
| Core Positioning | Biocontrol strain focusing on disease prevention and control | Compound functional strain for disease prevention + growth promotion |
| Characteristic Metabolites | Macrolide antibiotics, chitinase, volatile bacteriostatic substances, bolidomycin; hardly secrete a large amount of natural plant hormones | Streptomycin, spiramycin, succinic acid; natural secreted auxin and cytokinin (most prominent feature) |
| Target Diseases | 【Fungi】Fusarium root rot, wilt, verticillium wilt, phytophthora rot, fusarium rot, anthracnose, fruit tree rot disease【Bacteria】Bacterial wilt of tomato / pepper, ginger blast, potato scab. It is good at controlling compound soil-borne diseases caused by continuous cropping obstacles. | 【Fungi】Root rot, damping-off, southern blight, target spot, powdery mildew【Bacteria】Ulcer, soft rot, bacterial angular leaf spot, bacterial leaf diseases of foliar parts; better performance when sprayed |
| Functional Characteristics | 1. Strong rhizosphere colonization ability, tolerant to high humidity. 2. Degrade autotoxic substances secreted by root systems, relieve continuous cropping obstacles. 3. Mainly inhibit and lyse pathogenic fungal hyphae; weak growth-promoting effect. | 1. Hyphae form networks in soil to improve soil aggregates in long term. 2. Directly secrete growth-stimulating hormones to boost root growth and revitalize weak seedlings. 3. Solubilize phosphorus and activate soil medium and trace elements to improve fertilizer utilization rate. |
| Application Focus | Priority for: aged continuous cropping fields, root rot / wilt / high-incidence bacterial wilt fields, fruit tree root rot, soil-borne diseases of Chinese medicinal herbs. | Priority for: seedling bed root promotion, seedling recovery after transplanting, spraying for bacterial foliar diseases, fields requiring seedling yield increase, saline-alkali / low-yield degraded land. |
| Application Method(Total viable count ≥1 billion CFU/g) | Flexible application methods: root irrigation, base application, foliar spray. Foliar spray has outstanding effect on bacterial leaf diseases, diluted 500-800 times. 1–2 kg per mu for root irrigation / base application. | Mainly applied by root irrigation, base application and flushing, focusing on root disease control. Dosage: 1–2 kg per mu; dosage can be properly increased for heavily diseased continuous cropping fields. |
| Limitations | Less effective than Streptomyces microflavus in promoting root growth and regulating plant vigor | Weaker inhibitory activity than Streptomyces rimosus against severe wilt, verticillium wilt and heavily continuous cropping soil. |
