Trap Crops

In this episode of Hydroponics Daily, Dr. Russell Sharp delves into the intriguing world of trap crops. Unlike carnivorous plants, which evolve to gain nutrients from catching and decomposing animals, trap crops are used as a strategy to control pests within crops. Examples include radishes protecting carrots from wireworms and mustard attracting caterpillars away from cabbages.

Dr. Sharp discusses the controversial nature of trap crops and the limited scientific evidence supporting their effectiveness. While they may offer benefits, such as reducing pest numbers, they also pose risks. These include attracting more pests or inadvertently increasing pest populations if not managed correctly.

The episode also explores unique examples like the South American plant, Philcoxia, which attracts and decomposes nematodes using its underground sticky leaves. With insights into using plants like marigolds for aphid control, this episode offers a comprehensive view of the potential and pitfalls of trap crops in gardening and hydroponics.
