SOLANO CASTILLO, Tulio F.; CASTILLO AVILA, Marcia L.; MEDINA MEDINA, José V.  and  DEL POZO NUNEZ, Elio M.. Effectiveness of nematophagous fungi on Meloidogyne incognita (Kofoid and White) Chitwood on tomato in field conditions in Loja, Ecuador. Rev. Protección Veg. [online]. 2014, vol.29, n.3, pp. 192-196. ISSN 1010-2752.

This work was aimed to evaluate the effect of isolates of the fungi Pochonia chlamydosporia (Goddard) Zare and Gams (Hypocreales: Clavicipitaceae) and Purpureocillium lilacinum Luansa-ard et al. (Hypocreales: Ophiocordycipitaceae) in the Meloidogyne incognita (Kofoid and White) Chitwood control in tomato in field conditions. The assay comprised six fungic isolates and a control without fungi, in a ramdomized block design. In treated plants the gall index and the nematode population in roots and in the soil were reduced in comparison with the untreated plots. The number of fruits, the weight of fruits and yields were enhanced in the plots treated with the fungi. These results are a contribution to the solution of the root-knot nematode problem in the conditions of Loja, Ecuador, with local resources and no harmful to the environment.

Keywords : nematophagous fungi; Meloidogyne incognita; Pochonia chlamydosporia; Purpureocillium lilacinum; tomato.
