What's happening to my avocado plant?

My avocado plant is losing one of his three leafs. It starts with a small brown spot on the leaf but the spread is fast. In a small amount of time the two other leafs will have the same problem. It happened also with the three other leafs one month ago.

Hi Jeroen Delvaux This lesson is a kind of first symptom of necrosis subsequently that may grow a blighting appearance of the whole leaf. Predominantly the lesson comes out of a fungal infestation and spread all over the leaf lamina by proliferation of mycelium of fungal bodies. The growth and spreading of such fungal disease are supposed to be better managed by using copper oxychloride wettable powder dissolved in water or mancozeb or Carbendazim. So, you can ck in Plantix library for a similar symptom like Raspberry Spur Blight or Alternaria Late Blight and compare.
