Panama disease include mostly sanitation and quarantine practices to prevent the spread of Panama disease out of infected fields. However, the most effective tool against Panama disease is the development of banana trees resistant to "Fusarium oxysporum f. sp. Cubense". Unfortunately, the clonal reproduction of banana has led to a consequential lack of other varieties. Efforts are being made to produce resistant varieties, but with bananas being triploids which do not produce seeds, this is not an easy task. Creating clones from tissue cultures, rather than suckers, has proven somewhat successful in breeding resistant varieties, however, these tend to have decreased success
Crop art mosaic portraits by Lillian Colton are also examples. Her seed portraits of celebrities were exhibited in the strictly defined "Crop art" category at the Minnesota State Fair beginning in 1966. Rules for entry of Crop art allow "only seeds from Minnesota-grown farm crops or cultivated garden flowers, fruits, and vegetables" with no wild plant seeds permitted.
