JINMAI-Biological Shield® Plant Acid Growth & Protection Agent is a multifunctional agricultural bio-stimulant designed to improve plant vitality while providing natural protection against pests and diseases. The formula is developed through an advanced tertiary purification and high-temperature distillation process, ensuring a high-purity plant acid extract combined with rich organic matter and natural wood vinegar.
With 500 g/L plant acid and 180 g/L organic matter, the product works as both a plant growth regulator and crop protection enhancer. It improves nutrient absorption, stimulates root activity, and enhances crop resilience against environmental stress, pathogens, and insect pressure.
Unlike traditional single-function products, this solution integrates growth stimulation, disease suppression, and pesticide synergistic effects into one formula, making it suitable for modern integrated crop management programs.
By strengthening seedlings, improving flowering and fruit set, and protecting roots from soil-borne pathogens, the product helps farmers achieve stronger crops, higher yields, and better quality harvests.

Key Features

⦁ Advanced Plant Acid Extraction Technology
The product is manufactured using a high-temperature distillation and multi-stage purification process, ensuring a concentrated and stable plant acid solution. This process preserves active organic compounds while removing impurities, resulting in a product with consistent agricultural performance.
⦁ Integrated Pest & Disease Prevention
The plant acid and wood vinegar components create an unfavorable environment for many pathogens. The formula helps suppress fungal diseases, bacterial infections, and certain crop viruses, while also providing a mild insect-repelling effect. It is especially effective in reducing the occurrence of root rot, soil-borne pathogens, and physiological yellowing.
⦁ Powerful Root Development and Seedling Strength
Organic acids and natural compounds stimulate root metabolism and improve root elongation. This leads to stronger seedling establishment, better nutrient uptake, and improved resistance to transplant stress.
⦁ Enhanced Flowering and Fruit Formation
The formula supports flower bud differentiation and pollination efficiency, improving fruit set and reducing flower drop. This makes it particularly valuable during key reproductive stages of crops.
⦁ Agricultural Adjuvant Function
Natural surfactant components provide better spreading, adhesion, and penetration on leaf surfaces. When used together with pesticides or foliar fertilizers, it significantly improves absorption and overall application efficiency.
Product Efficacy
⦁ Stronger Root Development
Plant acids and organic compounds stimulate root activity and encourage deeper root growth. A stronger root system improves water and nutrient absorption while helping prevent root rot and transplant stress.
⦁ Enhanced Nutrient Uptake
The organic components improve nutrient availability and transport within plants, allowing crops to absorb fertilizers more efficiently. This helps reduce yellow leaves, nutrient deficiencies, and weak plant growth.
⦁ Natural Pest and Disease Resistance
Plant acid and wood vinegar help suppress harmful pathogens while creating a mild repelling effect against insect pests. Regular use strengthens plant resilience and reduces disease pressure during crop growth.
⦁ Better Flowering and Higher Yield
The formula promotes flower bud differentiation and improves fruit set, reducing flower drop and encouraging more uniform fruit development for higher yield potential.
⦁ Improved Spray Efficiency
As a multifunctional adjuvant, the product enhances spreading and penetration of pesticides and foliar fertilizers, helping active ingredients absorb more effectively and improving overall treatment performance.

FAQ
1. What is plant acid and how does it benefit crops?
Plant acid is a natural organic compound extracted from plant materials. It improves soil microbial activity, enhances nutrient availability, and stimulates plant metabolism, leading to stronger growth and better resistance to environmental stress.
2. Can this product replace pesticides?
No. While it helps suppress pathogens and repel certain insects, it is primarily a biostimulant and adjuvant. It works best when integrated with standard crop protection programs.
3. Is the product safe for organic farming?
The formula is derived from natural plant sources and organic matter. However, organic certification requirements vary by country, so users should confirm compliance with their local organic standards.
4. Can it be mixed with fertilizers or pesticides?
Yes. The product is designed with spreading and penetrating agents, making it suitable for tank mixing with many pesticides and foliar fertilizers to enhance their performance.
5. How often should it be applied?
Most crops respond well to applications every 7–15 days, especially during early growth, transplanting, and flowering stages.
6. Does it help reduce transplant shock?
Yes. The organic acids and root-stimulating compounds improve root establishment, reducing transplant stress and improving seedling survival rates.
