Reaction of Cultivar Coffee 'Vitória INCAPER 8142' of Cornillon to Parasitism of Meloidogyne exigua
Among factors limiting to the yield of the coffee crop are the diseases, deserving prominence the nematode Meloidogyne exigua. The objective of this work was to assess the level of resistance of 13 clones (1V, 2V, 3V, 4V, 5V, 6V, 7V, 8V, 9V, 10V, 11V, 12V and 13V) wich composes the clonal variety &#...
