Efficient control starts with diagnosis: most prevalent nematode species in Brazil

Brazilian crops face an invisible threat: phytoparasitic nematodes that attack roots, reduce yield, and complicate management. Knowing which species are most common is fundamental for quick diagnosis and efficient control strategies. Main genera and species found in Brazil In the country, four genera of phytoparasitic nematodes stand out due to their frequency and potential to cause damage: Meloidogyne, Pratylenchus, Heterodera, and Rotylenchulus. The following are the most recurrent cases by crop: Meloidogyne spp. (root-knot nematode) It is considered the main group of agricultural nematodes in terms of distribution and impact. Among the species, M. incognita and M. javanica are frequently cited as the most aggressive and widely distributed in soybean, corn, and cotton crops. In sugarcane crops, for example, the species M. javanica, M. incognita, and the lesion nematode Pratylenchus zeae are pointed out as the most common. Embrapa Pratylenchus spp. (lesion nematode) This species ...
