Factsheet of the month: August – Sulphur to control powdery mildew in cashew

Sulphur to control powdery mildewLast weekend, a team of experts from the Naliendele agricultural research institute (NARI) held a seminar in Tanzania to present lectures on the prevention and control of pests affecting cashew. Although cashew production in Tanzania has declined since the 1970s, it remains an important cash crop in the coastal regions of the country. The seminar, held in Mkinga District, aimed to bring extensionists and researchers together to promote the exchange of ideas and provide the extension officers with the knowledge to be able to advise farmers on how to improve the health, and therefore the yields, of their cashew crop.

Powdery mildew is the most important disease facing cashews in Tanzania and was the subject of one of the lectures held in Mkinga District. The disease, which is caused by a fungus, causes patches of white powder to appear on the surface of the leaves and other plant parts. To find out about how sulphur can be used in the management of powdery mildew on cashew,  read the Plantwise Factsheet for Farmers created by employees from Mkuranga District Council and the Ministry of Agriculture in Tanzania. This factsheet is also available in Swahili.
