Lantana Leaf with ring type spots
Hi, of late my Lantana and Rangoon creeper are suffering from unknown diseases. Grey spots on the upper surface of Lantana leaves and brownish powdery substance mainly on the leaf underside. I am seeking some help to find out what are the main causes, are these fungus and how to go about treating it? My location is in tropical Malaysia. Thank you very much.
