“…Herradura et al [61] evaluated the root necrosis index for R. similis following the method of Speijer and De Waele [29]. The extent of root damage was described by the following scores: 1 if the roots were all healthy, 2 if most roots were healthy, 3 if most roots were dead, and 4 if all the roots were dead.…”

Bananas are a staple food that considerably contributes to both food security and income generation, especially in countries of Africa, Asia, and Central and South America. The banana plant (Musa spp.) is affected by various pathogens, of main concern being the plant-parasitic nematodes associated with the rhizosphere, the most important of which are Radopholus similis (burrowing nematode), Helicotylenchus sp. (spiral nematode), Pratylenchus sp. (root lesion nematode), and Meloidogyne sp. (gall nematode). Infected plants reduce their ability to absorb water and nutrients, which can lead to delayed flowering, fewer bunches, and lower fruit mass. Obtaining nematode-resistant banana cultivars through genetic improvement is an effective and sustainable option compared with chemical control with nematicides. Here, we provide the first systematic review of existing banana sources of resistance to nematodes to aid the management and control of nematodes in banana and plantain crops. Articles selected from different databases were evaluated, and searches were conducted using pre-established inclusion and exclusion criteria. We found 69 studies dealing with genetic improvement for nematode resistance in banana cultivation. Our findings revealed that sources of resistance are currently under investigation to combat the diseases caused by different nematode species in banana plants.

“…The extent of root damage was described by the following scores: 1 if the roots were all healthy, 2 if most roots were healthy, 3 if most roots were dead, and 4 if all the roots were dead. This scoring has been used for evaluating damage caused by R. similis [42,69] as well as H. multicinctus [21,39].…”

“…Plant diseases have been a major problem for both the export industry and producers serving domestic markets. Besides the recurrence of Foc TR4, the following diseases were reported: Moko, black sigatoka, (Stover, 1986), nematodes (Davide, 1988; Herradura et al, 2012; Aggangan et al, 2013), and bunchy top (Kohnen et al, 2013; Molina et al, 2009). The Foc TR4 had been reported in Mindanao since 2009 and affected a range of banana production systems located in the area.…”

Coordination as Management Response to the Spread of a Global Plant Disease: A Case Study in a Major Philippine Banana Production Area

2019

View full text Add to dashboard Cite

An integrative management approach to the spread and emergence of global plant diseases, such as the soil-borne fungus Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4), entails a combination of technical measures and the responsiveness and awareness of area-specific constellations supporting conditions conducive to interactions and coordination among organizations and actors with different resources and diverse interests. Responses to banana diseases are mostly studied through technical and epidemiological lenses and reflect a bias to the export industry. Some authors, however, indicate that cross-sector collaboration is crucial in responding to a disease outbreak. Earlier studies on the outbreak of diseases and natural disasters suggest that shared cognition and effective partnerships increased the success rate of response. Hence, it is important not to focus exclusively on the impacts of a pathogen at farm or field level and to shift attention to how tasks and knowledge are coordinated and shared. This paper aims to detect whether and how the emergence of Foc TR4 is a driver of coordination. The case study focuses on the interactions between a variety of banana producers and among a range of public and private actors in southern Philippines. The analysis identifies distinct forms of coordination emerging in the context of three organizational fields responding to Foc TR4, which underlie shared capacity to handle and understand the spread of a global plant disease. The research is based on qualitative key informant interviews and document analysis and on observations of instructive events in 2014–2017. Analysis of the composition and actions developed in three organizational fields leads to distinguishing three theory-driven forms of coordination: rule-based, cognition-based, and skill-based. The combination of these three forms constitutes the possibility of a collaborative community, which conditions the implementation of an integrative management approach to mitigate Foc TR4.

“…Sin embargo, en estudios realizados por Marín et al (1999), en Costa Rica, obtuvieron reducciones del 4,8% en la AP de Musa AAA 'Grand Naine', a los 56 días después de la inoculación con 200 R. similis. Así mismo, Herradura et al (2012) encontraron reducciones del 8,2% y 25% en la AP en dos cultivares de Musa AAA, del Sudeste Asiático en respuesta de las plantas a la infección con 1.000 R. similis, en etapa de floración y cosecha.…”

El objetivo de este estudio fue evaluar la respuesta de cuatro materiales de musáceas a diferentes densidades de población de R. similis en condiciones de almácigo. A los 45 días después de siembra, 448 plántulas de plátano (Musa AAB ‘Dominico hartón’, Musa ABB ‘Guineo’) y de banano (Musa AAA ‘Gros Michel’ y Musa AA ‘Bananito’) fueron inoculadas con 0, 100, 500, 1.000, 3.000, 5.000 y 10.000 hembras de R. similis. Las plantas se evaluaron a los 60 y 90 días después de la inoculación(ddi) bajo un diseño experimental completamente aleatorio. En las variables peso seco total de plántula-PSTP y longitud de raíces-LR, R. similis ocasionó más del 48% de reducción en promedio. Los materiales de plátano fueron más susceptibles al nematodo con poblaciones finales promedio en raíces-PFNR de 215.575 y 134.181 individuos/100g de raíces en ‘Guineo’ y ‘Dominico Hartón’, respectivamente; mientras que en ‘Gros Michel’ y ‘Bananito’ se obtuvieron 82.676 y 44.897 individuos, respectivamente. La población inicial del nematodo presentó una correlación lineal negativa (P<0,05) con el factor de reproducción-FR, es así que con poblaciones iniciales de 100 y 500 individuos el FR fue el más alto en todos los genotipos; por el contrario, con las poblaciones entre 1.000 y 10.000 individuos, el FR fue significativamente menor en los cuatro genotipos de musáceas. En conclusión, las plántulas de los materiales de plátano tuvieron menores valores en las variables PSTP y LR al igual que PFNR, mientras que en los materiales de banano el daño fue menor.
