thrips on Prayer Plant
Quick answer
If your Prayer Plant has thrips, the most likely cause is: Unique symptom of thrips feeding on pigmented Maranta foliage. Thrips rasp and suck leaf juices, rupturing epidermal cells and triggering the leakage of anthocyanin-rich sap, which appears as a 'purple residue' or dark sticky spots. This is often accompanied by silvery stippling or linear scarring.
Start here:
- 1. Perform a 'Magnification Check' on leaf undersides for tiny, slender motile insects and black fecal specks (frass).
- 2. Wipe leaves with 70% isopropyl alcohol to remove residue and kill crawlers.
