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 weed Crop weed Crop weeds are weeds that grow amongst crops. Examples of crop weeds include chickweed, barnyard grass, dandelion, striga and fallopia japonica. Despite the potential for some crop weeds to be used as a food source, many can also prove harmful to crops, both directly and indirectly. Crop weeds can inhibit the growth of crops, contaminate harvested crops and often spread rapidly. They can also host crop pests such as aphids, fungal rots and viruses. Cost increases and yield losses occur as a result. Striga, one of the main cereal crop weeds in Sub-Saharan Africa, commonly causes yield losses
