Abstract

The objective of this study was to evaluate the growing of soil improving crops on the population of Rotylenchulus reniformis in naturally infested soil. It was evaluated the effect of 6 species of plants as cover crops in winter and 13 summer species and a fallow treatment on the nematode population under greenhouse. After 60 days, the root system was collected. Then, a sample of soil was taken in order to extract juveniles from the soil and quantification the final population of the pathogen in each pot for determining of the reproduction factor (RF). Fallow and all winter species of green manure, except hairy vetch, reduced the population of R. reniformis after cultivation in infested soil, in comparison to the control. Regarding summer cover crops, it was observed that sorghum 'SI03204' (Sorghum vulgare), millet 'BRS1501' (Pennisetum glaucum), Brachiaria ruziziensis, finger millet (Eleusine coracana), estylo 'Campo Grande' (Stylosanthes capitata x S. macrocephala), peanut 'IAC Tatu ST' (Arachis hypogaea) and dwarf velvet bean (Mucuna deeringiana) reduced the population of R. reniformis, when compared to the control, could be used in the management of this nematode.
