Abstract
The objective of this study was to evaluate the efficacy of using Lumbricus rubellus to control Meloidogyne incognita in Lactuca sativa roots. The experiment was carried out at the Laboratory of Soil Microbiology from the university Universidade do Oeste Paulista. We evaluated the worm species Lumbricus rubellus together with nematodes of the species Meloidogyne incognita and used fertilization with organic manure (cow and bird). For testing, we used Lactuca sativa, and the study was done using soil for growing vegetables in three-litter pots inside a greenhouse where relative humidity and temperature were monitored. After 45 days, the pots were removed and analysed. Analysis showed that, in comparison to the other situations analysed, the combination of bird manure with the worms resulted in a lower count of nematodes in the roots and better development of the plants. Therefore, there is a possibility these worms are effective in the biological control of nematodes.
