A-104 Broad Spectrum Fungicide is a compound functional microbial agent independently developed by Shandong Baolai-Leelai Bio-Tech Co.,Ltd.
This product integrates nutritional growth promotion with biological disease control. It is formulated with multiple scientifically combined high-activity functional microbial strains and bioactive substances such as seaweed extract. Through microbial technology, it is designed to systematically address intensive cultivation challenges, including soil-borne diseases, continuous cropping obstacles and soil degradation.
It helps improve crop stress resistance and quality, making it an ideal biological input for reducing chemical pesticide and fertilizer use and promoting green, sustainable agriculture.
Competitive Exclusion:
Beneficial microbial communities rapidly colonize the rhizosphere, occupy ecological niches and physically block pathogen invasion.
Secretion of Antimicrobial Substances:
Core strains such as Paenibacillus polymyxa secrete various active metabolites, including antimicrobial lipopeptides, bacteriocins and extracellular lytic enzymes. These substances directly inhibit or degrade the cellular structures of pathogenic fungi and bacteria.
Induced Systemic Resistance:
The product activates crop defense signaling pathways, such as jasmonic acid and salicylic acid pathways, enhancing overall disease resistance.
The product shows strong preventive effects against persistent soil-borne diseases such as bacterial wilt, fusarium wilt, root rot, anthracnose and phytophthora disease, including both fungal and bacterial diseases.
Long-term application can significantly reduce pathogen populations in the soil, helping to fundamentally relieve replant disease caused by continuous cropping.
The product enriches soil microbial diversity, improves soil aggregate structure and helps relieve compaction.
It secretes organic acids, auxins and other substances that promote root development and elongation, especially the growth of fine roots. This helps build a stronger underground system for nutrient absorption and plant support.
The product helps activate fixed phosphorus, potassium and other medium and trace elements in the soil, improving fertilizer use efficiency.
It also improves plant nutrition and physiological metabolism, resulting in faster seedling recovery, stronger growth, more uniform flowering and fruit setting, better fruit quality, earlier maturity, and ultimately higher yield and economic return.
Suitable for solanaceous and cucurbit vegetables such as pepper, tomato, cucumber, watermelon and strawberry; field crops such as corn and cotton; fruit trees such as apple, grape and citrus; as well as cash crops such as tea and Chinese medicinal herbs.
This product is suitable for use throughout the entire crop growth cycle. For best preventive performance, it is recommended to apply before disease occurrence or at the early stage of disease development.
| Application Method | Recommended Dosage | Application Timing and Method | Expected Key Effects |
|---|---|---|---|
| Drip Irrigation / Flushing / Root Irrigation | 1–2 kg/mu per application | Apply after transplanting, before flowering, during fruit swelling and other key growth stages. Dilute 500–1000 times before application. | Key preventive protection; promotes root and seedling growth; protects flowers and fruit. |
| Base Application / Furrow Application / Hole Application | 2–3 kg/mu | Apply during soil preparation or before transplanting. Mix evenly with organic fertilizer before application and cover with soil after application. | Improves the rhizosphere soil environment and builds a healthy microbial ecosystem from the source. |
| Flushing Application | 1–2 kg/mu | Can be applied at the seedling stage or immediately after transplanting. Use 2–3 times throughout the full growth cycle for better results. | Promotes rapid root establishment and provides continuous protection throughout the crop growth cycle. |
| Warning | Do not mix with chemical fungicides or strong oxidizing agents. If needed, apply at an interval of at least 5–7 days. | — |
Trial Background:
In 2025, the product was applied at a large-scale pepper planting base in Xuchang, Henan Province.
Trial Plan:
Based on conventional field management, the treatment group received an additional application of Junduoduo at 1 kg/mu after transplanting.
Result Comparison:
Root System:
The treatment group developed a stronger root system with more white roots, significantly improving water and nutrient absorption capacity.
Plant Growth:
Plants showed vigorous growth, compact internodes and dark green leaves.
Disease Resistance:
The incidence of fusarium wilt, phytophthora blight and other diseases in the demonstration area was significantly lower than in the control area.
Yield and Quality:
Flowering occurred earlier, the fruit-setting rate increased noticeably, and the peppers showed uniform shape and bright color. Both the marketable fruit rate and total yield achieved considerable improvement.
Conclusion:
Junduoduo effectively built a healthy rhizosphere environment for pepper plants, creating a full-chain positive effect from growth promotion and disease defense to quality improvement and yield increase.
Green and Safe:
This product is a pure biological preparation with no chemical residue. It is environmentally friendly and complies with green and organic agricultural production standards.
Good Compatibility:
It can be used together with most organic fertilizers and non-strongly alkaline chemical fertilizers, creating synergistic effects.
Company Commitment:
With a complete R&D and quality control system, we ensure stable viable counts and reliable product performance.
