Phosphonate Fertilizers from Alqawafel Proven to Suppress Root-Knot Nematodes in Peer-Reviewed Study

Innovative phosphonate formulations deliver 100% juvenile mortality and up to 98% root gall reduction in tomatoes—confirming Alqawafel’s leadership in sustainable nematode management.

Summary

Alqawafel Industrial Agricultural Company’s phosphonate-based fertilizers—Calphos®, Magphos®, and Phosphoros®—have been scientifically validated for their nematicidal effects against Meloidogyne javanica and M. incognita. Published in the Journal of Nematology (Vol. 43, No. 2), this independent study conducted by the University of Jordan demonstrates the fertilizers’ effectiveness in inhibiting egg hatching, causing complete mortality of juvenile nematodes (J2s), and significantly reducing root galling in tomato crops.

Background: A Growing Need for Eco-Friendly Nematode Control

Root-knot nematodes (RKNs) are among the most destructive agricultural pests, severely impacting tomato, cucumber, and eggplant crops across the MENA region and beyond. Traditionally controlled through synthetic nematicides, farmers now face environmental regulations, soil health concerns, and rising resistance—prompting the need for integrated, sustainable nematode management strategies.

Research Methodology

Three liquid phosphonate fertilizers developed and manufactured by Alqawafel were evaluated:

• Calphos® (Calcium Phosphonate)
• Magphos® (Magnesium & Potassium Phosphonate)
• Phosphoros® (Potassium Phosphonate with added nitrogen)

Laboratory and greenhouse experiments assessed the products’ effects on:

• Egg hatching inhibition
• Second-stage juvenile (J2) mortality
• Root galling severity
• Reproductive factor (RF) and egg mass production
• Tomato plant biomass (root and foliage weight)

The study included standard chemical nematicide (Vydate L®) and untreated controls for benchmarking.

Key Results

Magphos® emerged as the most effective product, outperforming the chemical control in several metrics.

Implications for Growers and Distributors

This study confirms that Alqawafel’s fertilizers go beyond crop nutrition—they act as bio-functional solutions for root-knot nematode suppression.
Key benefits for farmers include:

• Improved plant protection without reliance on harsh chemicals
• Enhanced root system development and shoot biomass
• Cost-effective and environmentally conscious pest control

For global distributors and agronomic partners, this validates Alqawafel’s role as an R&D-driven manufacturer providing science-backed solutions for modern agriculture.

Expert Insight

“Our collaboration with academic researchers reinforces what we’ve seen in the field: phosphonate chemistry is a game changer in integrated nematode control,” said Eng. Ahmad Albess, Founder of Alqawafel. “This is proof that locally developed innovation can compete globally—safely, effectively, and sustainably.”
