Crop rotation controls disease. It operates by reducing the populations of disease-causing organisms in the soil and on stubble. It is most effective against soil-borne diseases but can also control many air-borne diseases. Rusts, viruses, and any seed-borne diseases such as loose smut of wheat are not controlled by rotation. Practices such as tillage and fertilisation can also control disease. The best crops to rotate are those which are botanically different, e.g. a cereal and a legume, as these are affected by different diseases.
