Levantamento da ocorrencia de Meloidogyne exigua (Nematoda) nos cafeeiros (Coffea arabica) do estado de Minas Gerais
The occurance of Meloidogyne exigua Goeldi, 1887 (Nematoda, Heteroderidae) was observed in 35 counties of the State of Minas Gerais. This nematode was found in seedlings of different ages, in young crops and in crops as old as 80 years. There was no evidence of galls in the coffee plantings that received chemical fertilizers annualy, with split application of nitrogen. Numerous galls were observed in those plantings which received only manure and which had a natural mulch. The development of nurseries is not recommended in forests with soils from forests without sterilization of these soils. It was observed that the variety Conillon (Coffea canephora) was resistant to Meloidogyne exigua under field conditions. Experiments are suggested using this variety as the stock and various varieties of Coffea arabica as the scion. This can be accomplished by a method similar to that suggested by Reyna
