Peruvian ginger has gained a market presence abroad. However, phytosanitary issues represent the primary setback in production, with nematodes of the Meloidogyne genus being a significant concern. The study’s objective is the morphological identification and behavior of ginger under different population densities of Meloidogyne spp. The research was conducted under semi-controlled conditions in La Molina (pots) and in open environments in Pichanaqui (bags), both using 2000 cc of substrate. The morphological identification part was carried out in the UNALM Nematology Laboratory. Samples for morphological identification and inoculation were collected from commercial ginger fields displaying characteristic nematode symptoms. Twenty females and two males were isolated from the sample for morphological identification. Of the females, 11 exhibited characteristics of M. exigua (55 percent), seven of M. incognita (35 percent), and two of M. javanica (10 percent). Furthermore, the two males confirmed the presence of M. incognita. On the other hand, the treatments included five different inoculation levels: 5, 50, 500, 1000 (eggs/100 cc of soil), and a control treatment with no inoculation. Significant differences were observed in both indirect parameters (plant height, aerial and root weight, etc.) and direct parameters (nematode reproduction, host efficiency, plant behavior). However, there were marked differences between greenhouse and Pichanaqui data. According to the evaluated parameters, it was established that ginger cultivation is an efficient host for Meloidogyne spp. In this study, a production loss of up to 80 percent was observed with the highest treatment, along with a gradual reduction in rhizome quality with all inoculated treatments.
