oa Journal of the Entomological Society of Southern Africa - Notes on potato aphids and leaf roll spread at different South African localities



The present South African seed potato areas are dependent on a constant introduction of virus free seed potatoes from overseas to supply the potato industry with a sufficient amount of good quality seed potatoes. Despite the fact that virus free seed potatoes are planted, the quality of the seed potatoes produced has not everywhere been satisfactory even though the farmers make serious efforts to produce good seed. The object of this paper is to report on investigations aimed at finding areas suited for seed potato production, establishing why they are suited and why others are not, or are less so and at evaluating methods of producing tolerably good seed potatoes in less successful areas.
