“…Daniells and O’Farrel (1987) found that harvesting at a 200 cm vs. 10 cm height increased bunch mass on the follower by 12% and decreased time to the next harvest by 5%. In this study, the significant reduction in weevil damage could have compensated for the yield loss that one would have expected.…”

“…The rationale for low harvesting of plants is to accelerate desiccation of residues, a condition unfavourable for weevil development. Harvesting low has however been shown to impact negatively on yield by reducing bunch mass (Daniells and O’Farrel 1987). Some nutrients may be lost to a plant from using harvested pseudostems for mulch as opposed to senesced pseudostems that may ‘feed’ followers through direct nutrient translocation (Wortman et al.…”

The banana weevil, Cosmopolites sordidus, is the most important insect pest of banana and plantain in the world. Cultural control methods were investigated over 2 years in southern KwaZulu‐Natal, South Africa. Harvesting at ground level and dissection of remnants (treatment 1), and covering the base of the mat (entire plant consisting of several meristems) with soil and moving debris to the inter‐row (treatment 2), were compared to a positive control that involved treatment of plants with a registered pesticide (treatment 3), and a negative control that involved harvesting at 150 cm from the collar with no soil or sanitation amendments (treatment 4). Yield, weevil damage and pseudostem girth of plants were measured from August to November annually, while adult beetle densities were assessed over 4 weeks in October/November and April. Nematode samples were taken and analysed in October/November every year. Damage parameters included the coefficient of infestation, the percentage coefficient of infestation (PCI) at two intervals, the summed PCI value, the percentage cross‐sectional damage of the central cylinder and cortex, and the mean cross‐sectional damage percentage. A randomized block design with three replicates was used in the trial. The parameters were similar before the onset of the trial. Fruit yield and plant girth, corrected by nematode densities, were not significantly different in any treatment, nor were the nematodes controlled. Soil cover and recession of remnants was the only effective treatment, significantly reducing the CI, but not the adult density or the other damage parameters. Soil cover showed promise as a cultural control method because it only needs to be applied seasonally and reduced the percentage cross‐sectional damage of the central cylinder, the damage parameter most closely related to yield, by 14%.

“…The height at which to cut down the old pseudostem after bunch harvest, was investigated by Daniells and O'Farrell (1987). They found that cutting high (2 m) increased bunch mass on the follower by 12% and decreased time to the next harvest by 5% compared with cutting low (0.1 m), however, this practice should be avoided where weevils are present (Chapter 12).…”

“…No se observó la presencia de escamas y de áfidos en ambos experimentos así como de algún otro insecto plaga. Farrel (1987), Lahav y Turner (1992), Wortman et al (1994), Hassan et al (2000, el pseudotallo de la planta madre, luego de su cosecha, contribuye a la nutrición mineral del hijo de sucesión. En respaldo a las consideraciones sobre el flujo de nutrimentos de la madre recién cosecha al hijo de sucesión, tanto Araya y Vargas (2000) como Rodríguez et al (2006) encontraron que conforme aumentó la porción retenida de pseudotallo en la planta madre a la cosecha, mayor productividad presentó el hijo de sucesión, resultado que documenta bajo condiciones tropicales (Costa Rica y Colombia, respectivamente) el traslado de nutrimentos antes mencionado.…”

Durante el 2006 se realizaron 2 experimentos en plantaciones comerciales de banano (Musa AAA, cv. Grande Naine) del Caribe de Costa Rica. En ambos el primer tratamiento fue la eliminación periódica y el segundo la retención total, hasta el colapso, del tejido deteriorado del pseudotallo luego de la cosecha. Se midieron las variables de crecimiento, producción, enfermedades e insectos plagas. Excepto por el largo de la segunda mano en el experimento 1 (p=0,0309) y de la sexta mano en el experimento 2 (p=0,0455), no hubo diferencias entre tratamientos en las restantes variables de crecimiento (p > 0,1480) y de producción (p > 0,0652), ni presencia de pudrición por Erwinia spp. En ambos experimentos se observó la ocurrencia de daño por larvas de C. sordidus, pero éste, además de que fue de una baja magnitud, solo difirió entre tratamientos (p=0,0227) en el experimento 2. Se observó pudrición del cormo asociada con el picudo negro únicamente en el experimento 1, cuya expresión, además de ser baja, no difirió entre tratamientos (p > 0,7574). Se determinó la presencia de Pseudococcus elisae y de Periplaneta spp., solamente en el experimento 1; con ambos insectos, los mayores valores (p < 0,0412) se observaron en el tratamiento 2 (retención total). No se observó la presencia de escamas y áfidos en ninguno de los 2 experimentos. Dado que no hubo diferencias en crecimiento y producción entre tratamientos, la selección de uno de ellos estaría dada por factores de riesgo asociados con insectos plaga y/o enfermedades comunes al cultivo del banano.
