Se realizaron dos muestreos poblacionales, uno previo a la aplicación de tratamientos, y otro a los 120 días posteriores, obteniendo el número de nematodos en 100 g de suelo. Los tratamientos Nemmax (a dosis de 2, 4 y 6 L ha con 3 aplicaciones), Nemacur 400 CE (Fenamifos) (3 L ha-1 una aplicación) y un testigo absoluto. En el control de Meloidogyne incognita, se observó diferencia significativa en el tratamiento 5 (133.2), que representa al testigo, ya que se observó un incremento en la población de los nematodos, comparado con los demás tratamientos, los cuales fueron iguales estadísticamente, presentándose las mismas diferencias para Pratylenchus spp. Con el nematodo Dorylaimus spp., se presentaron diferencias estadísticas, siendo el tratamiento 5 (249.6) con mayor diferencia, 4 (18), 1 (8.2), 2 (6) y 3 (3.4).

The objective of this study was to evaluate the biological effectiveness of the nematicide of biological origin Nemmax, for the control of Meloidogyne incognita, Pratylenchus spp. and Dorylaimus spp., associated to this crop in Motozintla, Chiapas, in 2014. Two population samplings were carried out, one prior to the application of treatments, and another one to the 120 days later, obtaining the number of nematodes in 100 g of floor. The Nemmax treatments (at doses of 2, 4 and 6 L ha with 3 applications), Nemacur 400 CE (Fenamiphos) (3 L has one application) and an absolute control. In the control of Meloidogyne incognita, a significant difference was observed in treatment 5 (133.2), which represents the control, since an increase in the population of the nematodes was observed, compared with the other treatments, which were statistically equal, presenting the same differences for Pratylenchus spp. With the nematode Dorylaimus spp., statistical differences were presented, with treatment 5 (249.6) with the greatest difference, 4 (18), 1 (8.2), 2 (6) and 3 (3.4). Treatment 3, of Nemmax at a dose of 6 L/ha was the one that presented the lowest population of the filiform nematodes of the genus Meloidogyne incognita, Pratylenchus spp. and Dorylaimus spp.]]></p></abstract>
