What Is Phytotoxicity?
Phytotoxicity means “plant poisoning.” It happens when a substance—like a chemical, salt, or even a natural extract—harms the plant instead of helping it.
⚠️ What Causes It?
Some common causes of phytotoxicity include:
| Cause | Example |
|---|---|
| ???? Overuse of chemicals | Too much fertilizer or pesticide |
| ???? High salt concentrations | Excess sodium chloride (NaCl) |
| ???? Hormones or stimulants | Overdosing with salicylic acid |
| ???? Inoculants or microbes | Pathogenic fungi used incorrectly |
| ☀️ Environmental triggers | Applying treatments under strong sun |
???? Signs of Phytotoxicity in Trees:
- ???? Yellowing leaves (chlorosis)
- ???? Leaf burn or brown edges
- ???? Leaf drop or wilting
- ???? Stunted growth or death of shoots
- ???? Internal tissue rot (especially in trunks after injection)
???? Example in Agarwood Inoculation:
Let’s say you inject too much NaCl or strong fungal spores—instead of helping, it can damage the tree’s tissues. This stress might:
- Stop growth,
- Kill living cells, or
- Even prevent resin formation.
✅ Farmer Tips to Avoid Phytotoxicity:
- Follow correct dosage – Don’t “overfeed” the tree!
- Dilute strong substances – Always test on one tree first.
- Monitor after treatment – Watch for leaf burn or early signs.
- Use proper timing – Avoid mid-day heat or rainy season.
- Use tested protocols – Trust what’s been field-proven.
