Step around the base and see if moles have tunneled around thru the roots. That is usually what I find when I have a small tree that wilts suddenly but will come back when I water it only to be wilted again the next day.

No moles... The ground is still saturated too so I am sure it has enough water.

Any other ideas?

How big/old is the tree?  I would like to see more pictures of the tree and the base also.

it's not that old. I bought it in the fall and would guess it's about 1.5-2 years old. it is about 4 feet tall.

Without seeing the whole tree, I would say it is a combination of stress from the bloom and lack of water.

Its not the surface that is the issue (which is why just lawn sprinklers are of little help to younger trees).  In general, from the picture,  it looks pretty dry.

It looks dry, but it is still pretty wet. We got a heavy rain last night but it still looks the same... should I clip the droopy particles or do anything else?

My Keitt is flushing out and some of the new flushes are looking bad.

I noticed when troubling the new leaves, a skinny brown beetle with a white spot came out. Around the size of an ant, but longer.

Here are some flushes on the same tree that are fine-ish:


Should i remove the diseased looking flushes?

I think this is spider mite, but hoping the other forum members will chime in. I'm getting a bad infestation of the same thing on a couple of my mango trees.

I have had the same problem on all my mango trees except Venus. I think it is not diseased; it is just the bugs taking a particular liking to the new growth. I used Sevin on one of the trees (Maha Chanok) just as the swollen buds were about to push out and that worked. The  new growth came out good and healthy looking.  I tip-pruned  most of the other trees and I am planning to use Sevin or Organocide just when the branches push new growth.

I got some close-up shots of the little buggers. I watched with a magnifier, and they stick a needle like thing in the mouth area into the tender foliage and suck the sap. What the heck are they?

OK. Sevin will work, but it will cause some collateral damage. Very toxic to the guys keeping your soil healthy -- earthworms and millipedes. I tried it once years ago and found piles of dead millipedes the next day. I might try a pyrethrin based product.

Thanks for the information, Jeff. How about Safer insect  killing soap? It is organic. I think spraying the tree just when the new growth is about to push out is key. I have seen new growth completely die because of the bugs. They do not seem to be interested in anything other than really tender foliage.

Never tried it. Oils here tend to burn. Yah, the trick is finding something that won't burn tender foliage. I wish someone could identify this pest so that we could figure out a good control measure.

Safer soap is about useless.

So, one person believes that the insect damaging the mango leaves is a mirid. I'm starting to wonder if we had an outbreak of avocado mirids which caused both the swiss cheese avocado leaves (and low fruit set) and the ratty looking new mango growth.

Fortunately, the mango damage is mostly cosmetic at this point, because I'll be pruning all of the affected trees back this summer. So, rather than hit it with insecticide, I'm just going to pick off new shoots and prune out the affected foliage. I think the mirid population will dwindle once the hell heat of south florida summer kicks in.

I noticed the two insects in your picture look like different bugs based on their anatomy although it could be angle and clarity.

Have you been able to find any pictures to id the mirid if thsts w h at it is?  Have you had any unusual fruit drop on m a ng and/or avocado?

I found some pictures that look very similar to the bugs. But, I haven't had much luck finding info on them in the context of mango. Dr Crane was the one who thought it could be a mirid, but he wasn't sure. I"m still waiting to hear back from a couple of other people.

I took a look at the new flushes and i didn't see and bugs around.
I removed it and spot sprayed sevin near the terminals, hopefully the next flush is better.
Seem like with this Keitt ever other flush is messed up.

So what effect will running sprinklers have on mango production? I am trying to control the amount of water they get as to not to over water when fruiting. The grass has taken a hit the last 2 years, and pretty much scorched earth with beautiful mango trees LOL  Will using sprinkler system to irrigate grass 2-3 time a week screw up anything related to the mangoes?
