Trap Plant Species




  • The French Marigold (Tagetes patula) is one of the more well known Trap Plant Species

    I recently wrote about Trap Plants and Trap Crops. I had said that I would publish a listing of trap plant species, so here it is, but before I begin, I need to say a few things.

    First, the chart below lists the Main Crop species in bold first, and then the Trap Plant Species is listed underneath as a bullet. Finally, the pest that is drawn away from the Main Crop is listed after the Trap Plant Species.

    Second, this list represents only plant pairings for which I could find solid research. There may be other legitimate trap plant species out there, but I did not find anything that proved it. If you come across a pairing, AND you have some research to back it up, please send it my way, and I will add it to my list.

    Third, as I come across more research, I will be adding it to this list.

    Fourth, and finally, a word about names.  I call these plants (as do many scientists) Trap Plants. Many people may call this Companion Planting, and they would be correct. To me, Companion Planting is any plant pairing that aids the growth of the main crop. It may also aid the growth of the companion plant as well, but that is getting into a whole new subject. Now a Companion Plant may provide nutrients, provide minerals, add fertilizer, attract beneficial insects, provide shade or structural support, or it may repel pests.  Trap Plant planting is a specific type of Companion Planting that draws a pest to themselves and away from the main crop. I hope that makes sense.  I plan to write about this in more detail in the near future as well.
