Observaciones sobre la distribución espacial de Meloidogyne incognita después de la cosecha en dos plantíos de tabaco burley [Nicotiana tabacum].
Two burley tobacco (Nicotiana tabacum L.) fields (A and B) were sampled inmediately after harvest at Repunta, Perez Makin county, Costa Rica, to perform observations on the spatial distribution of Meloidogyne incognita larvae. In each field, samples were taken horizontally at 5, 10 and 15 cm from th...
