Crop rotation for Pratylenchus brachyurus control in soybean
Nematropica 44 (2), 146-151
Abstract: In recent years, the root-lesion nematode (Pratylenchus brachyurus) has been responsible for damage and economic losses in various crops and numerous regions throughout Brazil. The aim of this study was to evaluate the effects of succession cropping on the population of P. brachyurus in soybean. Two experiments were carried out in the greenhouse, using soil naturally-infested with nematodes and the following cropping sequence: soybean (90 d)-treatment (60 d)-soybean (60 d). The treatments were soybean (control), maize, brachiaria grass, intercropped maize-brachiaria, crotalaria, oilseed radish, stylosanthes, and fallow. In the first experiment, the nematode population under brachiaria and intercropped maize-brachiaria was lower that with maize and soybean, but in the second experiment, there was no statistical differences compared to maize. Crop succession with crotalaria, oilseed radish, stylosanthes and fallow promoted the greatest reductions in the population of P. brachyurus.
