Claude W. Fuller (1 October 1872 Castle Hill, New South Wales – 5 November 1928 Lourenço Marques) graduated from Australia's Melbourne University.
He widened the ambit of his post by doing a survey of local fungus diseases and plant parasites, and performed valuable work on the control of locusts.
During his stay in Natal he devoted a large amount of time to the control and extermination of orchard pests and noxious weeds.
The virus is spread by insects and shows as pale yellow or yellow-white leaves, leading to stunted plants that cannot not produce cobs.
In the same year he went to Brazil to bring back a parasite to control fruit flies which had become a major pest in South African orchards.
