Knowledge Bank - Agriculture

The purpose of this page is to signpost plant health information from across sectors that is relevant to food production systems.

About This Page

Plant health information in these pages is aimed at practitioners in large scale food production systems such as grains, oilseeds, pulses, potatoes and other vegetables and fruit grown as a crop. Much information is available online and in print to help identify disease symptoms, the organisms that cause them, and to provide guidance on management and biosecurity. Here we have collected sources we judge to be generally reliable for information on these topics. You can use the Resource Type button to filter, search by keyword, or scroll through all together. The information on these webpages concerns the many common pathogens that are regularly encountered in food production systems as well as invasive non-native species (INNS) or those which have recently become problematic, possibly due to climate change. See Getting Started for good places to begin in identifying both common and INN organisms.

Getting Started

Good resources for identifying disease causing organisms include the AHDB Encyclopedia of Pests and Natural Enemies, AHDB The Encyclopedia of Cereal Diseases, AHDB Crop Walkers Guides and CABI Plantwise Diagnostic Field Guide. Detailed information on most disease causing organisms can also be found on the Plantwise Knowledge Bank Database (Plantwise fact sheets). Websites which provide searchable information to help identify disease causing organisms and provide information on management are listed under Treatment and Management or Field Guides and Self Diagnostics. For help identifying insects contact the Royal Entomological Society or SASA. Discussion fora are listed with newsletters and periodicals under Newsletters. Whether the organisms are INNS or common pests and diseases, be sure to practice good biosecurity.

Reporting Notifiable Pests

Most pests encountered will not be notifiable but if you think you may have encountered a notifiable pest it is important that you report it quickly. In Scotland notify the Horticulture and Marketing Unit at SASA. Outwith Scotland, consult the Plant Health Information Portal for other UK reporting contacts.
