Anthracnose Disease symptoms: Attacks both the leaves and the fruit, which are sensitive fromflowering to the midgrowth stage. Most of the rot found in mature fruit comes from the infection of young fruit. The small spots develop into large, brown spots indicative of fruit rot. Finally, a white mycelium appears on the fruit during storage Fruit rot Disease symptoms: Fruit rot of litchi has been a serious problem. Litchi is host to a range of post-harvest pathogens, often with quite different modes of infection. Several fungi have been found to be associated with diseases Usually large water soaked lesions appear on the surface of fruits. Initially the disease symptoms are perceptible on injured portion of the fruits. With the advance of the disease the decayed areas get depressed. The rot gradually penetrates deep into the pulp. Ultimately rind of infected fruits cracks off exposing the pulp which subsequently is covered with thick Cottony mycelium. Such affected fruits emit an odour of fermentation. Root rot Disease symptoms: A slow decline and a sudden death of plant have been recorded in litchi. It can affect the whole tree or just one or two branches. The symptoms include a sudden branch wilt that is followed by the decline of new growth on the affected branch over a period. In other situations, the tips die without wilting. The tree or branch may recover temporarily, but subsequently dies. Parts of the tree flush and grow, while other sections die. In some parts of litchi belt, trees are killed by the root rot. One side of the tree’s crown may be perfectly sound and the other totally necrosis. Leaf shed never occurs (it does in the case of a nematode attack) and the internal parts of the roots are characteristically red in colour No method has been found to save the tree once it has become infected.
