🦠 Different methods

Nematode management is most effective when multiple preventive and suppressive tactics are combined. This lesson introduces major non-chemical methods used in agricultural systems.

---

Regulatory Control

Regulatory measures reduce spread through quarantine, inspection, and movement restrictions on planting material and soil-contaminated inputs.

National and regional quarantine frameworks are foundational for preventing new nematode introductions.

---

---

Cultural Control

Cultural tactics include healthy seed or planting material, crop rotation, sanitation, tillage timing, flooding where suitable, trap cropping, and use of antagonistic crops.

These practices lower inoculum pressure and slow population buildup.

---

---

Physical Control

Physical methods include soil heating, solarization, hot-water treatment of propagules, and related disinfestation approaches.

Effectiveness depends on exposure duration, target stage, and temperature achieved.

---

---

Resistant Varieties and Field Hygiene

Host resistance and removal of heavily infested plants reduce multiplication and field carryover. Resistance should be used with rotation and sanitation for durability.
