Diagnosing a pest problem

To be able to provide effective solutions to a plant health problem, it’s first important to diagnose a pest problem accurately. The diagnostic tool allows you to diagnose a crop problem through the symptoms observed and the part of the plant affected.

From the Plantwise Knowledge Bank home page, navigate to the diagnose a pest problem tile and click ‘identify a pest’.

Narrow down cause

The first step in narrowing down the cause of a plant health problem is to determine which part of the plant is affected by the pest. In some cases, several parts of the plant can be damaged, but to help diagnose the problem, the main part of the affected plant needs to be determined. The options provided in the tool include leaves, stems, whole plant, seeds, fruit, growing point, inflorescence, roots and vegetative organs.

If the type of problem is already known it will help to narrow down your search further, otherwise a user would select ‘unsure’. The types of problems in the tool include mites, insects, fungi, nematodes and weeds.

The steps in the diagnostic tool mirror the plant clinic prescription form found on the data collection app.
