Re: Lagoestromia indica, Pest
Aphids will do that to crape myrtle. Could be any of a number of insects that suck the juices out of leaves -- weevils, stinkbugs, other Hemiptera. Do you see any insects? Look in the evening or at night.
The pictures are a bit fuzzy, so I can't see if the leaves have been eaten (beetles or slugs/snails).
Do I also see signs of chlorosis? That is very common with crape myrtle. Add a dose of micronutrients or use a fertilizer with them already in it.

Re: Lagoestromia indica, Pest
Solution number one would be to stop using Osmocoat. You simply don't know when and with what dose your trees are being fertilized when you use any time-release fertilizer. You could -- statistically speaking -- have every one of those little balls of solution pop on the same day and time -- or never if, by happenstance the triggering temperature and humidity is not attained. Almost every houseplant fertilizer containes micronutrients -- or you can use an organic fertilizer (fish emulsion, for example) and buy a bottle of chelated iron solution (which seem always to have the other micronutrients in it) and add 20 cc to the bottle of fish emulsion.
Solution number 2 is to check your tree carefully (even with a hand lens) for any kind of critter on or under the leaves. Do it in the day, then again at night. Look very carefully. MY best guess would be aphids or mealybug or whitefly. Aphids can be hard to spot sometimes. Whitefly and mealybugs will be VERY evident. Check our Rogues Gallery at the top of this Forum. We at least have Aphids there.
There also are examples of the Hemiptera that could be doing this. It would only take a couple of them to do it. They're quite large -- at least 1/2 inch (2 cm).
Aphids can be controlled with a soap spray. But they all can be controlled with a pesticide that contains pyrethrins. There are several on the market up here. A rotenone spray will also kill them, but do not spray it anywhere within 50 feet of a stream or pod with fish or invertebrates in it!!!!! In any case, follow label directions.

.is there any possibility to save the stump?
Sure. It'll be OK. The sucking insects rarely kill a tree -- tho they can weaken it to the point that some disease can get a foothold.

Re: Lagoestromia indica, Pest
Looks OK to me. It's hard to diagnose from a picture, though.
