South Africa has one known registered fungicide approved for use in treatments, PSHB Fungicidal Reg. No. L10670 Act 36/1947 produced by Pan African Farms. This multifaceted formula, with Salicylic acid as active ingredient, is organic (all ingredients are plant-based) and there exists a low risk for the fungus to develop resistance. It is recommended to be used with the PSHB Supplementary Surfactant which incorporates a 2% mixture of the insecticide Cypermethrin, targeting the PSHB directly.
