Well, I see by my pin on the map that I am the only member outside the US. We have purchased a house on grounds that were once an avacado plantation. We have many wonderful trees that are full of fruit - and some that aren't and seem to have some type of fungus. We also have 3 fantastic cactus gardens I wished you could all see - but it's the fungus on the avacado trees that has me worried. They have a white 'crystal type growth' on the places where limbs have been cut and then the limbs themselves seems to be covered with a brownish-dust that when you touch it comes off white. I am NOT a gardner. Yes, I once grew very large zuchinni and tomatoes but that's about it. So any suggestions or help would be greatly appreciated!

I don't have much time but found a University of California site that may help figure out if your avocado's are suffering from some disease or pest.
Click here! Avocado diseases and insect problems

I know when you cut limbs from avocado's or wound them (for example kids hitting the bark with an object) they will produce a white crystal fungus looking "stuff". Most of the time the tree will heal itself if it was from a cut or wound....at least that is from past experience. I don't know why the branch would be having the fungus.
Take a look and read the info contained in the above link and see if it will help. Take a look at Avocado Black Streak first and see what you think!

Maybe someone else has more info they can help with. Please keep us updated with information you have found it could help someone else with the same problem.
