Those clearly are contrails... normal, harmless, everyday, contrails...
Nothing sinister...
Contrails are nothing more than clouds... water vapor... That is why they hang around so long... Just like clouds....
On the other hand,... Sprays or dustings, dissipate quickly...
This is why the trails that skywriters and planes at air shows don't linger like contrails...
If anything was being intentionally sprayed, it would dissipate much faster...
So,.. the entire logic behind the contrail conspiracy uses backwards logic...
They have the physics reversed...
Them is just harmless vapor clouds...
