Crop Diagnostic Tools
Below are some useful tools for identifying and diagnosing crop problems. This is only a selection. Please let us know of other useful tools we should add.
Remember, identification is only the first step. Similar symptoms can have different causes, and multiple problems may be involved. Where important management decisions are involved, verify the diagnosis before acting.
AI-assisted identification
AI photo recognition is increasingly useful for identifying plants, weeds, insects, and some crop diseases. It can provide a useful starting point, but a photograph alone may not reveal the actual cause of a crop problem.
Always verify important diagnoses and recommendations using a credible technical source or local expert.
