There is a fungal disease called 'brown spot'which leaves brown spots on the leaves and fruit of mandarins. This fungus tends to live on dead twigs and branches and the spores are spread by wind and rain. The disease is common in cool damp weather, and where the foliage dries slowly, this disease is likely to thrive. The best time to take action to prevent this disease from spreading is in spring when the buds are bursting and when 50 - 75 percent of the petals have fallen. We suggest spraying with a copper spray - Yates Leaf Curl Copper Fungicide at this time. Further sprays at 6-8 week intervals may be required,depending upon weather conditions. At this stage it would be a good idea to prune off all dead material and dispose of it.
