The gall nematode, belonging to the genus Meloidogyne, stands out among phytomatomatoids for its rapid reproduction and adaptation in the most varied places and climates of Brazilian regions. There is a difficulty in controlling them with chemical nematicide due to the damage to human health and the environment. In this way, alternative measures to create balanced agriculture are currently being researched. One of the main alternative methods for nematode control is the use of antagonistic and non-host plants in crop rotation. This study aimed to evaluate the effect of different antagonistic plants on the population reduction of Meloidogyne javanica. The experimental design used was completely randomized, with 5 treatments and 6 repetitions, conducted in a factorial arrangement (2x5), being: T1 (Control); T2 (Crotalaria juncea); T3 (Crotalaria spectabilis); T4 (Mucuna aterrima); and T5 (Fagopyrum esculetum). Initially, the nematode was multiplied in tomato plants in a greenhouse. Subsequently, the nematodes were extracted from tomato and 1250 eggs + J2 of M. javanica were inoculated in antagonistic plants for multiplication for 60 days. The variables analyzed were length and root weight; number of eggs and juveniles in the roots; and reproduction factor. Mucuna aterrima was efficient with the lowest number of eggs and reproduction factor. In the number of juveniles, Fagopyrum esculetum and Crotalaria juncea had the lowest number, but did not differ statistically from each other.
