Nematodes are among the most influential organisms in agriculture: both as destructive pests and as valuable allies. Their dual role makes them critical to understand for anyone committed to sustainable crop production.
The Two Faces of Nematodes
Nematodes are microscopic roundworms found in nearly every soil ecosystem. Some species, known as plant-parasitic nematodes, attack roots, reducing nutrient uptake and causing significant yield losses. These pests are a silent threat, often going unnoticed until damage is severe.
On the other hand, entomopathogenic nematodes act as biological control agents, targeting insect pests without harming plants. They are a cornerstone of sustainable pest management, offering a sustainable alternative to chemical pesticides.
Why understanding nematodes matters
For growers and agricultural technology providers, distinguishing between harmful and beneficial nematodes is critical. Mismanagement can lead to crop losses or missed opportunities for natural pest control. This is where expertise in nematode screening and soil sampling becomes essential.
Crops on which we operate
Vegetais
- Potatoes – susceptible to Globodera spp. (potato cyst nematodes).
- Tomatoes – root-knot nematodes (Meloidogyne spp.) are common.
- Broadacre
- Soybeans – soybean cyst nematode (Heterodera glycines).
- Corn (maize) – root-lesion nematodes (Pratylenchus espécies).
- Sugar beet – beet cyst nematode (Heterodera schachtii).
- Onion and garlic- Ditylenchus dipsaci
Fruits
- Pome and stone fruits – Pratylenchus vulnus
- Citrus – citrus nematode (Tylenchulus semipenetrans).
At SynTech Research Group, we specialize in:
- Nematode pest screening to identify plant-parasitic species early.
- Soil sampling and analysis to assess nematode populations and soil health.
- Integrated Pest Management (IPM) studies that incorporate nematodes alongside chemical and microbial solutions.
Nematodes in IPM: Challenges and Opportunities
Integrating nematodes into IPM programs is not without challenges. Compatibility with other control methods, environmental conditions, and crop-specific factors all influence success. SynTech’s research teams develop customized pest management programs and conduct compatibility studies to ensure nematodes complement existing strategies.
By combining biological, chemical, and cultural controls, IPM programs reduce reliance on synthetic pesticides while maintaining crop productivity. Nematodes, both as pests and protectors, are central to this approach.
Our global network and standardized protocols allow us to deliver reliable data across diverse agro-climates. Whether it’s screening for nematode pests or validating biocontrol efficacy, SynTech provides actionable insights that help clients make informed decisions.
