Crop walker guides

Growers can encounter a wide range of crop problems that can quickly render plants unsaleable unless recognised, diagnosed and dealt with promptly. Often, such problems are linked to pests and diseases, but nutritional and cultural-related disorders may also be involved.

AHDB Horticulture Crop Walkers’ Guides (CWGs) were designed to assist growers, supervisors and nursery staff in the vital task of monitoring crops for the identification of many of the economically important pests, diseases and disorders. 

Hard copy versions of these CWGs are no longer avaialble from AHDB but the digital versions can still be accessed from the links below.

The AHDB Horticulture weed identification guide published in 2016 can be accessed from the pocket weed guide page.
