GUZMAN, Óscar Adrián; CASTANO, Jairo  e  VILLEGAS, Bernardo. EFFECT OF SANITARY CLEANNESS OF PLANTAIN (Musa AAB SIMMONDS) CORMS ON PLANT PARASITIC NEMATODES. rev.udcaactual.divulg.cient. [online]. 2012, vol.15, n.1, pp.87-95. ISSN 0123-4226.

The use of vegetative seed of banana and plantain favor the dissemination of plant parasitic nematodes such as: Radopholus similis, Pratylenchus coffeae, Helicotylenchus multicinctus, H. dihystera, Meloidogyne incognita, M. javanica and Rotylenchulus reniformis. The objective of this study was to determine the effect of the sanitary cleanness "peeled" of corms of Dominico-Harton plantain on seedlings’ development and plant parasitic nematodes population, in the nurseries. The assay included six treatments, each one, with 20 corms, distributed as follow: 40 corms with sanitary cleanness "peeled" in sterilized soil, with and without immersion in aldicarb; 40 traditional corms with and without immersion in aldicarb;and,40 corms with sanitary cleanness "peeled" with and without immersion in aldicarb, in infested soil with plant parasitic nematodes. The treatments were assigned in a completely randomized experimental design. The best treatment was the use of sterilized soil (free of nematodes) and corms with sanitary cleanness, without having statistically differences using or not aldicarb, since was not found plant parasitic nematodes after 50 days, in comparison to the other treatments in which the population of nematodes ranged between 143 y 2,495 individuals on 100g of roots and between 11 and 18 nematodes on 100g of soil. The results demonstrated that the practice of the sanitary cleanness "peeled" of corms, allows producing seedlings free of nematodes, which favors good growth and development of the seedlings, permitting to bring clean planting material to the field.
