“…Onion is a well-known companion plant that acts as a natural insect repellent (Dancewicz & Gabryś, 2008). It is successfully used as a plant companion in developing countries that do not rely heavily on agricultural machineries (Altieri, 2012; Parker et al ., 2013; Sallam, 2013). Furthermore, Haan & Vasseur (2014) showed that root competition between lettuce and onion benefited the lettuce at the expense of the onion.…”

Decreased reliance on pesticides can be achieved through a clever use of eco-evolutionary knowledge via intercropping economically valuable crops with companion plants that can hamper pest outbreaks. We created a greenhouse multi-layered microcosm system to test two potato peach aphid clones, performing alone or in competition, on mixes of genetically variable cultivars of cabbage, with and without onion. The onion acted as a nuisance/disturbance for the pest, which was generally for the benefit of the cabbage albeit both plants sharing space and nutrients. The onion effect was context-specific and differed by aphid genotype. Onion variable nuisance negatively affected the numbers of one aphid genotype (green) across all contexts, while the other genotype (pink) numbers were decreased in two contexts only. However, the green performed better than the pink on all cases of cabbage di-mixes despite its numbers being capped when the onion was present. Further, there was also a general aphid propensity to wander off the plant along with a differential production of winged morphs to escape the onion-affected environments. Moreover, through a comparative increase in dry mass, which was subject to onion and aphid effects, a diversity effect was found where the cabbages of fully genetically variable microcosms sustained similar final dry mass compared with non-infested microcosms. Our findings provide fresh insights into the use of multi-layered contextual designs that not only allow disentangling the relative effects of genetic variation and modes of interaction, but also help integrate their benefits into pest management in view of companion planting.

“…Introduction Basil (Ocimum basilicum L., Lamiaceae) is an aromatic herb with repellent effects on different kinds of arthropods (Bomford 2004;Del Fabbro and Nazzi 2008). Several studies state its qualities as repellent or companion plant to decrease aphid, thrips and hornworm attacks when intercropped in fields, particularly of tomato crops (Schader et al 2005;Basedow et al 2006;Sujatha et al 2011;Parker et al 2013). Jolliffe (1997) reports that intercrop yields averaged 13% higher with basil than in monocultures.…”

In order to reduce the use of pesticides, banker plants may be added to crop systems. They can improve the presence of predatory arthropods by offering shelter or alternative food. In the present study, we analyzed basil as banker plant in a greenhouse IPM tomato crop system testing different plant combinations in monocultures vs. dicultures. We measured the influence of the presence of basil on the reduction of pest number, predator population stability, plant health and crop yield. Significantly fewer pests were present in dicultures when basil was present, but the number of predators, crop yield and leaf health was not statistically different between plant combinations. Under the given conditions, basil could not be categorized as an efficient banker plant for Macrolophus pygmaeus.

“…This is a good example of relational autonomy in practice. For instance, companion planting (Holmgren 2002, p. 165;Parker et al 2013) is one of the many ways permaculture uses design to enhance plant health by relying on cooperation.…”

Urban Food Autonomy: The Flourishing of an Ethics of Care for Sustainability

Urban agriculture is often advanced as a sustainable solution to feed a growing urban population, offering a number of benefits: improved fresh food access, CO2 absorption, social justice and social cohesion among others. Going beyond these direct tangible/objective benefits from urban agriculture, in this paper we ask: How can growing food in the cities teach us about taking care of each other and the natural environment? We use the example of urban food autonomy movements to discuss the transformative potential of a grassroots-led initiative promoting permaculture, which is anchored in three “ethics”: care for the earth, care for the people, and fair share. Through examining the philosophical underpinnings of “autonomy” and “care”, we explore how urban food autonomy initiatives can enable the development of an ethics of care, especially using permaculture inspirations. Our theoretical review and case analysis reveal that “autonomy” can never be achieved without “care” and that these are co-dependent outcomes. The urban food autonomy initiatives are directly relevant for the achievement of the three of the UN’s 17 Sustainable Development Goals: “Zero Hunger,” “Life on Land” and “Climate Action”, and contribute to a culture of care. Indeed, urban agriculture can act as a powerful education platform for the engagement of diverse stakeholders while also supporting a collective transformation of values.
