Nematodes in the Soil: Meet the Invisible Villains

Nematodes are microscopic organisms that attack plant roots, directly affecting crop development and productivity, according to information from Solum Laboratory. Knowing the main genera present in the soil is essential for more assertive management and to reduce losses during the harvest. Among the most common types is Meloidogyne spp., known as root-knot nematode, which forms swellings on roots and hinders water and nutrient absorption, being frequent in crops such as soybeans, cotton, vegetables, and corn. Pratylenchus spp., or lesion nematode, penetrates and moves internally in the root, causing necrosis and compromising root system functionality. Another notable genus is Heterodera spp. and Globodera spp., called cyst nematodes, which form resistant structures on roots, able to remain viable in the soil for several years, mainly affecting soybean, wheat, and potato crops. Rotylenchulus reniformis, known as reniform nematode, is a semi-form parasite that attaches to roots and ...
