Chronogastridae

Susceptible crops: These nematodes are polyphagous, attacking a broad range of crops including cereals, vegetables, and ornamental plants. The infestation is particularly damaging during the seedling stage, as the nematodes target the delicate root systems, hindering the plant's ability to uptake nutrients.

Biology and life cycle: The life cycle of Chronogastridae is heavily influenced by soil moisture and temperature levels. They proliferate in environments with sufficient humidity, where they pass through several developmental stages in the soil profile. Their movement is dependent on the water films surrounding soil particles.

Damage and severity: Infestation typically leads to root tissue degradation and the formation of necrotic lesions. These lesions serve as entry points for secondary infections by fungi and bacteria. Symptoms in the field often manifest as patches of stunted, chlorotic plants, which leads to a significant decrease in total harvest quality.

Control measures: Managing Chronogastridae requires an integrated pest management (IPM) strategy to minimize the nematode population:

• Implement rigorous crop rotation practices to break the life cycle of the parasite.
• Utilize proper soil tillage to improve aeration and decrease moisture retention in problematic areas.
• Application of bio-nematicides or biological control agents like predatory fungi.
• Maintain optimal soil fertility to enhance the natural resilience of the plants against stress.
