JINMAI-VGer® Marigold Root Shield Nematode Control is a highly effective plant-derived biological nematicide formulated with concentrated marigold (Tagetes) extract and seaweed extract, combined with bioactive polyphenols, polysaccharides, and organic matter.
Marigold (Tagetes spp.) has long been recognized in agricultural science for its natural nematode-suppressing compounds, especially thiophenes, which can disrupt nematode development and survival. By integrating these natural compounds with marine bio-stimulants, this formulation not only controls nematodes but also stimulates root regeneration and enhances plant resilience.
The product targets the full life cycle of plant-parasitic nematodes—including eggs, juveniles, and adult stages—while promoting healthier root systems capable of resisting reinfection. Through the generation of reactive oxygen species (ROS) within the rhizosphere environment, the product disrupts the nematode nervous, digestive, and reproductive systems, reducing feeding activity and reproductive capacity.
Designed for soil drench and irrigation systems, this product offers a sustainable solution for long-term nematode management in both organic and conventional agricultural production systems, helping growers protect root health, maintain yield stability, and reduce reliance on synthetic nematicides.

Key Features
Product Efficacy
⦁ Effective Root-Knot Nematode Suppression
Controls major plant-parasitic nematodes such as Meloidogyne spp., Globodera spp., and Heterodera spp., reducing root gall formation and crop damage.
⦁ Root System Recovery
Stimulates root branching and root hair development, restoring the plant’s ability to absorb water and nutrients efficiently.
⦁ Improved Plant Vigor
Reduces the physiological stress caused by nematode infestation, allowing crops to maintain stable growth and productivity.
⦁ Sustainable Soil Health Management
Promotes a healthier rhizosphere environment while supporting long-term biological balance in the soil ecosystem.

FAQ
1. What types of nematodes can this product control?
The product is effective against several economically important nematodes, including root-knot nematodes (Meloidogyne spp.), cyst nematodes (Globodera spp.), and soybean cyst nematodes (Heterodera spp.).
2. How does marigold extract control nematodes?
Marigold extract contains natural bioactive compounds that disrupt nematode metabolism and development. These compounds interfere with feeding behavior, reproduction, and survival, gradually reducing nematode populations in the soil.
3. Can it be used in organic farming systems?
Yes. The formulation is based on plant-derived extracts and contains no synthetic nematicide residues, making it suitable for organic and eco-friendly agriculture when used according to local regulations.
4. When is the best time to apply the product?
Applications are typically recommended before planting, during early root development, or when early nematode symptoms appear, allowing the product to protect and regenerate the root system.
5. Can it be combined with fertilizers or pesticides?
Yes. The product generally has good compatibility with most fertilizers and crop protection products. However, a small compatibility test is recommended before tank mixing.
