Editing Radish (section)

=== Companion plant ===
Radishes can be useful as [[companion plant]]s for many other crops, probably because their pungent odour deters such insect pests as [[aphid]]s, [[cucumber beetle]]s, [[Manduca quinquemaculata|tomato hornworms]], [[Coreidae|squash bugs]], and [[ant]]s.<ref name=EarthWood /> They can also function as a [[trap crop]], luring insect pests away from the main crop.<ref>{{cite web|url=http://www.knowledgebank.irri.org/IPM/cultCtrl/Trap_Crop.htm|title=Trap Crop|access-date=24 May 2011|archive-url=https://web.archive.org/web/20070322215153/http://www.knowledgebank.irri.org/IPM/cultCtrl/Trap_Crop.htm|archive-date=March 22, 2007}}</ref> Cucumbers and radishes seem to thrive when grown in close association with each other, and radishes also grow well with [[chervil]], [[lettuce]], [[pea]]s, and [[Tropaeolum|nasturtiums]]. However, they react adversely to growing in close association with [[hyssop]].<ref name=EarthWood>{{cite web |url=http://users.netconnect.com.au/~ewood/companion_planting.html |title=Garden Companions and Enemies |author=Ready, Barbara |date=1982-02-01 |work=EarthWood |access-date=2014-07-30 |archive-url=https://web.archive.org/web/20140701075634/http://users.netconnect.com.au/~ewood/companion_planting.html |archive-date=2014-07-01 |url-status=dead }}</ref>
