“…The reduction of R. similis in banana roots was not significant (P < 0.05) whatever the plant combination. Our results were not concordant with those reported by [21] and [14]. These authors used the nylon mesh to separate the belowground parts of each plant in the intercropping system to avoid root interactions.…”

“…Many authors have reported the beneficial effect of intercropping for pest management particularly the control of nematodes. Intercropping banana with cover plants such as Crotalaria sp (Fabaceae), Tagetes sp (Asteraceae) and Mucuna sp (Fabaceae) have often been reported to reduce nematode populations by their ability to exude nematotoxic substances (deshydrolizidine, alpha-thiernyl, L-3.4-dihydroxyphenylalanine, respectively) into the soil [20,21]. Much of the banana production is done by smallholder subsistence farmers, with up to 87% of the world bananas being produced in these farming systems and consumed locally [22].…”

Aims: To investigate the combined effect of Arbuscular Mycorrhizal Fungi (AMF) and intercropping on the control of the nematode Radopholus similis in banana. Study Design: The study involved an experiment in which banana-banana monocrops alongside banana-groundnut and banana-sweet potato intercrops were inoculated with AMF Rhizophagus irregularis MUCL 41833 to control the nematode R. similis. Place and Duration of Study: Centre Africain de Recherches sur les Bananiers et Plantains (CARBAP), from September 2016 to April 2017. Methodology: An experiment was conducted under greenhouse conditions (photoperiod 12 h. average temperature 24 - 28°C and 70 - 80% relative humidity) and R. irregularis were tested against R. similis with banana intercropped with either groundnut, sweet potato or banana itself. The plants were cultivated in boxes (30 x 15 x 10 cm) containing sterilized (2x1hour at 121°C) sand/coffee ash substrate (proportion 1:2 v/v), as an intercropping system with the following plant combinations: Banana-banana, banana-groundnut and banana-sweet potato. The experimental set-up was a completely randomized design comprising four treatments and six replicates: (1): Nematode (Nem), (2) AMF, (3) AMF + Nema and (4) control without nematode and without AMF. The ratio of banana: intercrop was 1:1 in the intercropping treatments. A total of 72 boxes was considered in the experimental set-up. Results: AMF root colonization of banana was clearly affected by intercropping with about 25% increment observed in banana co-cultivated with groundnut or sweet potato compared to banana-banana combination. Positive effects of AMF expressed as an increase in banana biomass compared to the control treatment was observed in root fresh as well as shoot dry weights. However, the impact of AMF colonization in intercropping systems on R. similis did not confirm its bioprotective effect. Intercropping had a significant (P < .05) effect on R. similis and sweet potato has been shown to be more effective in controlling R. similis with 62% reduction compared to groundnut (24% reduction). Contrarily, banana plant growth decreased in the banana / sweet potato combination. Conclusion: Findings in this study indicate that R. similis biological control in the banana intercropping system is more dependent on the intercrop species than on AMF.

“…Sunn hemp intercrop significantly suppressed R. similis population and root damage; hence a better intercrop plant compared to the cowpea intercrop. This is probably because sunn hemp can be categorised as a poor host of R. similis while cowpea as an intermediate or good host ( Van der Veken et al 2008). Sunn hemp produces toxic exudates from its roots which are antagonistic …”

Radopholus similis is the most destructive plant parasitic nematode in banana production systems. A glasshouse experiment was carried out to evaluate the effect of legume intercrops on R. similis population and damage level in banana. A trial was laid out in a randomised complete block design with five treatments and five replications. The treatments were banana/cowpea (Vigna unguiculata) intercrop, banana/sunn hemp (Crotalaria juncea) intercrop, sole banana, sole banana with nematicide (Fenamiphos) and sole cowpea. Sunn hemp intercrop was suppressing R. similis population densities and reduced banana root damage the most compared to tested treatments. The legume intercropped banana plants had a significantly higher fresh root mass as the sole-cropped banana with nematicide while the solecropped banana without nematicide had significantly lowest fresh root mass. Sunn hemp and cowpea legumes are recommended for adoption by smallholder banana farmers as alternatives to nematicide use.

“…Interestingly, preference should be given to intermediate or good R. similis hosts (e.g., common bean and sorgho-Sudangrass), which can result in lower nematode build-up and reduced (long-term) pathogen pressure on the banana crop. Including a poor or non-host crop (e.g., marigold and sunn hemp) can result in an adverse effect on long-term pathogen pressure, as nematodes migrate to banana plants, the good host, aggravating the problem [132]. Conversely, break cropping with non-hosts can be effective where plantations are regularly shifted or replanted.…”

Functional Diversity of Soil Nematodes in Relation to the Impact of Agriculture—A Review

The analysis of the functional diversity of soil nematodes requires detailed knowledge on theoretical aspects of the biodiversity–ecosystem functioning relationship in natural and managed terrestrial ecosystems. Basic approaches applied are reviewed, focusing on the impact and value of soil nematode diversity in crop production and on the most consistent external drivers affecting their stability. The role of nematode trophic guilds in two intensively cultivated crops are examined in more detail, as representative of agriculture from tropical/subtropical (banana) and temperate (apple) climates. The multiple facets of nematode network analysis, for management of multitrophic interactions and restoration purposes, represent complex tasks that require the integration of different interdisciplinary expertise. Understanding the evolutionary basis of nematode diversity at the field level, and its response to current changes, will help to explain the observed community shifts. Integrating approaches based on evolutionary biology, population genetics and ecology can quantify the contribution of nematode fauna to fundamental soil functions. These include carbon transformation, nutrient cycling, pest control and disease transmission. In conclusion, different facets of nematode diversity such as trophic groups, life history traits, variability in body size and/or taxa identities in combination with DNA-based techniques are needed in order to disclose nematode–soil–ecosystem functioning relationships. Further experimental studies are required to define locally adapted and sustainable management practices, through ecosystem-based approaches and nature-based solutions.
