Greg says... best time to apply white oil to eridicate the scale insects that cause the sooty mould is in late spring. Apply every month through the summer and this hopefully will eventually get rid of the scale and then the sooty mould will dissappear. Another alternative if the tree is young, just wipe all the leaves to physically remove the sooty mould | About the Author Greg Kyogle 30th September 2007 3:08pm #UserID: 28 Posts: 32 View All Greg's Edible Fruit Trees |

Scott G says... My Black Sapote had sooty mould due to its proximity to a large eucalypt. The Sapote had no sap-sucking bugs on it. The plant seemed to grow ok. It looked as Trina described. New growth was comparatively green because it lacked the soot. And the amount of soot varied throughout the year. Trina: Can you find any sap sucking insects (like scale) on your plant? Also note that the sooty mould will not clear up immediately after the source has been removed. In fact it may cover the plant for months until it breaks down and is eventually washed off. Your plant may be struggling for other reasons. | About the Author Scott G Gold Coast 3rd October 2007 10:52am #UserID: 44 Posts: 117 View All Scott G's Edible Fruit Trees |
