Potatoes discharge a substance into the soil from their roots which attracts harmful worms. In some parts of Africa, these have reduced harvests to 40%.
A science team in North Carolina discovered that banana ‘paper’ can protect against such pathogens if the potato seeds are wrapped inside it.
The paper, made from unusable parts of the banana plant, absorbs the discharge, and worms no longer sense it.
Potato sizes and yields increased as a result. A simple 100 nanogram pesticide sample sprayed onto the paper was enough to substantially increase yield.
A very fruitful saving. Banana plants have other talents too.
