A new UN report states that it is dangerously misleading to suggest that pesticides are necessary to achieve food security. Instead, the report recommends that farms reduce pesticide use and adopt sustainable practices that protect crops from pests by enhancing biodiversity and natural enemies. This agroecological approach eliminates reliance on, and exposure to, expensive and toxic chemical inputs, but would it really allow farmers to be just as productive?

Cabbage is an important crop in Ghana where it grows all year round, right across the country. It is mainly grown for commercial production in Southern Ghana, in Akwapim and Kwahu areas and in the moist high elevations around Tarkwa.

Growing cabbage in Ghana is challenging since it can be attacked by a variety of pests, such as cabbage aphids, caterpillars, cabbage webworm, diamondback moth, mole cricket, snails and rodents. Worldwide, aphids are a major concern because they commonly spread plant-infecting viruses. These are often diagnosed as turnip mosaic virus and cauliflower mosaic virus, particularly in Europe and the US, according to Dr John Carr, University of Cambridge, UK (Phys.org, 2017).
