Phytopathological aspects of cashew (Anacardium occidentale L.) in Tanzania.
Abstract
The most important among the diseases contributing to the serious decline in production of this crop in Tanzania are powdery mildew (Oidium anacardii), anthracnose (Glomerella cingulata), die-back of shoots and inflorescences caused by Phomopsis anacardii, 2 leaf diseases (Pestalotia heterocornis and Pseudocercospora anacardii) and internal rot of the fruit caused by Nematospora coryli. Biological aspects of these diseases were investigated and correlated with weather conditions. Genetic resistance exists to O. anacardii and G. cingulata and control measures have been developed for some of the other diseases.
