    Issues in Rehabilitation of Cacao Forests due to Cu Toxicity
    Vast numbers of trees in the major cacao growing regions of West Africa (2/3 of global production of cacao) are dying from diseases. Moreover, many trees are old and long past their productive years. For these reasons, widespread cacao plantation rehabilitation via new plantings (upwards of 50 to 80 million new seedlings) is a key goal of these countries. However, a major barrier to successful cacao sector rehabilitation is a low seedling survival rate following planting-out. We suspect that a major contributor to the low planting-out success rate is soil contamination by Cu due to repetitive high-dose applications of Cu-fungicides in cacao farms over the previous 20 years. While Cu is an essential plant micro-nutrient, excess soil Cu can cause iron (Fe) chlorosis in plants, affecting productivity. Excess Cu can also be highly toxic and detrimental to development of cocoa seedling roots. Excess Cu tends to accumulate in plant roots, where it causes oxidative stress and disrupts uptake
