Crop diversity are all susceptible to a single fungus, "Fusarium oxysporum" (Panama disease); large areas of the crop were destroyed by the fungus in the 1950s. 'Gros Michel' has been replaced by the current main banana on the market, the 'Cavendish', which in turn is (2015) at risk of total loss to a strain of the same fungus, 'Tropical Race 4'. Such threats can be countered by strategies such as planting multi-line cultivars and cultivar mixes, in the hope that some of the cultivars will be resistant to any individual outbreak of disease. The implications of crop diversity are at both local
Crop Trust of plant genetics resources for food and agriculture. It also confirms the autonomy of the Crop Trust as a scientific organization in raising and disbursing funds. The Crop Trust is assembling an endowment fund, the income from which will be used to support the conservation of distinct and important crop diversity, in perpetuity, through existing institutions. Crop diversity is the biological foundation of agriculture, and is the raw material plant breeders and farmers use to adapt crop varieties to pests and diseases. In the future, this crop diversity will play a central role in helping agriculture adjust to climate change
