Description:	Cotton production in Brazil has become very expressive in late decade. In 2008/09 growing season, 866,012 hectares were grown to cotton, most of them in the Brazilian savanna. Production systems used in that region are based on monocropping, with very few or no crop rotations, intensive machinery traffic and the use of no-optimal sandy soils. This has lead to the selection, dispersion and build-up of plant-parasitic nematode populations. Root-knot (Meloidogyne incognita), reniform (Rotylenchulus reniformis) and root-lesion (Pratylenchus brachyurus) nematodes are the most common in the Brazilian savanna, being the root-lesion the most frequent one. Plant damage has been already observed in several cotton growing areas causing economic losses. The management of plant-parasitic nematodes in cotton in Brazilian cotton areas has not yet been considered as very important issue by farmers, and has been based on resistant cultivars, crop rotation and, in a less expressive way, on chemical nematicides
