Use crop rotation.

Crop rotation helps soil- or residue-borne pathogens, but leaf curl viruses (e.g., tomato leaf curl) are spread by insect vectors (whiteflies) and persist in alternate/weed hosts. Row covers, resistant varieties and controlling weeds/insects target the vector and hosts, so they are effective prevention measures.
