What Are Abiotic Disorders?
Abiotic disorders are plant problems caused by non-living, environmental factors rather than pathogens like fungi, bacteria, or insects. Common causes include drought stress, heat stress, waterlogging, compaction, nutrient deficiency or toxicity, herbicide drift or misapplication, and physical damage.
These disorders are frequently misdiagnosed as diseases or pest damage, leading to unnecessary and ineffective treatments. Correctly identifying an abiotic cause is critical — applying a fungicide to a drought-stressed lawn, for example, will not help and may make things worse.
