Thiram, a commonly used fungicide when exposed to Sporisorium sorghi and S. cruentum. Similarly, it has found to induce resistance to rust leaf in wheat through increasing the activity of pathogenesis related proteins. Conservation While the species as a whole has not yet been assessed, A. africanus subsp. walshii is considered to be endangered by the South African National Biodiversity Institute (SANBI). It is known only from a small area in the Elgin valley (less than five locations) and the population continues to decline. The largest subpopulation is threatened by unregulated informal settlement expansion. A proportion of the population is protected within the Kogelberg Biosphere Reserve and is not threatened.
