RITZINGER, Cecília Helena Silvino Prata et al. Evaluation of the nematode population in banana plantations with and without the use of organomineral. Rev. Bras. Frutic. [online]. 2011, vol.33, n.4, pp.1103-1110. ISSN 0100-2945.

With the demand for integrated production, monitoring becomes fundamental to reduce or to substitute pollutant inputs in the fertilization and in the management of pests. Many products have been used in production areas, without the proper registration or knowledge of its efficiency or its effect on pests and natural enemies. In the studied area, the use of organomineral is recommended as an alternative to the use of fertilizers and possibly with nematicidal effect. The evaluations, to verify the effect of this product, were accomplished, through five samplings, in the period of 2008 to 2010, in three properties, cultivated with banana cv. 'Williams' with the age ranging from 8 months to 13 years, in the Irrigation Project of Formoso, in Bom Jesus da Lapa, BA. In the study, ten samples composed by two subsamples of soil and roots were collected, in areas with and without the organomineral application. The damage level was determined using the visual scale and the data was submitted to ANOVA. There was significant interaction of nematode populations between years and properties and between organomineral utilization and properties (P<0.01). There was no correlation between damage level and organomineral utilization in the areas 1 and 3. However, there was negative correlation between the damage level and nematodes in the organomineral presence, in the area 3 (P<.01). Meloidogyne spp. was the species that had the highest population in Bom Jesus da Lapa, BA. The use of organomineral did not provide significant reduction in the nematode population. The damage level was low, which could not be explained by the use of the organomineral. Cultural practices interfere in the development of the plant nematode population and free life nematodes.
