Abstract

There are numerous publications for diagnosing crop and pasture growth problems. Although they are excellent for experienced people, they can be time consuming and possibly misleading for the less experienced.

Many guidebooks assume that the user has already decided that their problem falls into the category covered by their particular guidebook, for example, a disease, pest or herbicide problem.

Guidebooks are often based on plant symptoms. However, in the field, symptoms vary and different problems can have similar symptoms.

This bulletin presents a problem diagnosis method that uses plant symptoms and paddock clues. It can be used to draw up a short list of possible causes of an observed problem. Specialist decision aids can then be used to establish definitive causes. It has been presented for many years in training courses with the title Detective Doug.
