White Sapote leaf spots (forum)

George starts with ...
Hi, this is my first posting. My four metre tall 10 year old Pike seedling thats never fruited has a heavy infestation of black spots on the underside of almost every leaf. The larger leaves turn yellow and drop, new leaves are wilting. It's the third year in a row its happened but this time the tree looks like its dying. In my research i have not found any relevant information pointing to White Sapote leaf disease. Lace bugs was all I could find searching through online photos. Also are the fallen leaves a hazard for the future or can i use as mulch. Anyone have any experiences or solutions. Much appreciated.

George - very bad scale infestation that will kill a Casimiroa - must be a huge ant nest under it? Eco oil spray a few times and drench soil with soapy water from dish detergent 1tbs / 9lt - if that doesnt help much cut back by 30% which im thinking of doing to mine also at 4.5mt and never flowered also after 5y.

Hi Mark, I will try the above once the current rains pass. Beside the WS is a heavy bearing Prune tree that's also been infested the last 2 years with visible leaf bugs causing almost every leaf to curl. A metre past the Prune there is a narrow concrete path leading to the Hills hoist, a section of that path has been home to swarms of ants over many years. Are the affected WS leaves safe to mulch or should I dispose? Thanks
