Evaluation of grafting and nematicide treatments for the management of a root-lesion nematode, Pratylenchus sp., in Coffea arabica L. plantations in Guatemala
Root-lesion nematodes, Pratylenchus spp., are widely distributed on coffee in Guatemala, with a high negative impact on production. A field experiment was undertaken to assess damage by this parasite and to compare two control methods: grafting onto Coffea canephora, and nematicide treatments (terbufos). The experiment was carried out up to the third harvest (5 years). Nematode densities in the roots, coffee berry yield losses and plant mortality rates were highest on ungrafted C. arabica. Analysis showed that grafting and nematicide treatments had no significant effect on bean size and the chemical quality of coffee beans, or on the organoleptic quality of the beverage. These results are important as grafting on C. canephora is increasingly being used to control root parasitism in Guatemala and in other countries of Central America.
