Intercropping Reduces Agricultural Pesticide Use 42% Across 344 Chinese Farms

Crop Improvement
It shows that simply changing how crops are arranged in a field — something any gardener can do at home — can dramatically reduce the chemicals that end up in our food and waterways.
Scientists studied hundreds of farms in China where farmers grew two different crops together in the same field instead of just one. Farms that mixed crops used nearly half the pesticides of farms that grew a single crop, and their yields were more reliable each year. The best results came from pairing wheat with fava beans, or corn with soybeans.
Key Findings
Intercropping reduced pesticide applications by 42% on average across 344 farms compared to single-crop farming
Wheat-fava bean and maize-soybean pairings showed the strongest effect, with 51% and 47% pesticide reductions respectively
Yield stability improved by 30%, meaning intercropped farms had more consistent harvests year over year

Growing two crops side by side — a practice called intercropping — cut pesticide use by 42% across 344 Chinese farms, while also making harvests more consistent from year to year.
Abstract Preview
A nationwide survey of 344 farms practicing polyculture showed 42% reduction in pesticide applications compared to monoculture controls. The effect was strongest in wheat-fava bean (51% reduction) ...

Wheat is a group of wild and domesticated grasses of the genus Triticum. As cereals, they are cultivated for their grains, which are staple foods around the world. Well-known wheat species and hybrids include the most widely grown common wheat, spelt, durum, emmer, einkorn, and Khorasan or Kamut....
