avocado issues

[mikewhite85]

Yesterday I looked at a failing avocado that appeared to be affected by anthracnose and fireblight. At least that's what I think

It, of course, could be all blight and I am mistaking the earlier stages for anthracnose. Let me know if you think I'm on track.

As far as treatment goes I am going to prune out the throughly infected portions and clean my cutters between each cut. Unfortunately, all of the leaves on the tree except for some of the new growth seem to be speckled with brown- so I am not 100% sure what to do.

It's a little late to start applying copper fungicide, which I have read is supposed to be done every 7-10 days during the wet season (and to start 2 weeks beforehand). Of course I could start it now.

Also, I will relocate the nearby sprinkler head, which is probably the root of the problem

Any other ideas?

... you are on the right track... just cut that #### out and treat it towards the end of the wet season.... you ll never get rid of all of it completely... the best you can do is to control and minimize it.. if the trees are overwhelmed with that #### replace them....

Avocado's are really sensitive to environmental conditions. Salinity will cause the tips to brown and is a common problem in areas that have a high mineralization in their water.
Anthracnose will have brown along the vains of the leaves I think. Are there whole branches affected with the suspected fire blite?
Their are several diseases that'll turn an avocado's leaves black including anthracnose and phytophthora c and several others. Fire blite isn't that common in avocado's, but you can peel the bark off and see a discoloration if its fire blite.
I've been messing with avocados my whole life and have several in my yard,

Hello, I'm not sure how to post a new discussion, so apologies if this is in the wrong place!

I have planted an avocado seed right into the soil, in a small pot, some time ago
The seed sprouted a couple of weeks later, and I got leaves!! I was soooo happy that it grew!

Today, about a month or so later, it has about 10-12 leaves and I thought to transplant it into a bigger pot, looking at the size of the leaves.

I put it in a big pot and buried the seed into the soil, and within 10 min, all the leaves drooooped!!

I got soo worried and looked up diff forums, unsure whether the seed should be buried under the soil or still peeking out?

I panicked after a half hour and no change in the leaves, so put the whole plant back into the smaller pot with the seed peeking out !!

Still no change and I'm afraid the plant will die! I took great pains to get this seed and now I'm afraid all my effort will be wasted.....any help is appreciated, since I'm so scared my poor plant will die !!

Info: I live in an apartment, so don't have the capacity to plant into the ground, hence using pots
I'm in India, so the weather right now is quite sunny and cool, December winters in Bombay do not get cold at all!

Thanks

Avacodos go into shock really easy. Transplanting them if the roots are disturbed all the leaves will fall off. Major sudden upsets in their environment such as to much water or to little will effect them and cause dropping of leaves . I bet their just a little in shock from transplanting it.

When you transplant, try and retain all the soil from the original pot around the plant, so the plant sees a minimal change in its micro environment.
