Welcome to CropMonitor

This website provides information sourced from monitoring sites located across the country and reports up to date measurements of crop pest and disease activity in arable crops throughout England. The project is run by CHaP Ltd and additional data will be incorporated as the season progresses.

Live monitoring 2017

Live monitoring is now active. Keep checking for regular updates.


CropMonitor is changing! 01 Nov 2017
The CropMonitor website is being extended and updated to provide a new sophisticated decision support system for wheat, barley, oilseed rape and potatoes on behalf of the Crop Health and Protection Centre (CHAP). The first phase of the system will be available in the spring.  

CropMonitor - latest news on site locations 01 Nov 2017
We have currently confirmed 33 trials site locations where we will be monitoring up to five untreated varieties of wheat, barley and/or oilseed rape at each location. Each location has been equipped with a met station, spore trap and insect traps to monitor key pests and diseases. This network is being operated as a collaboration between Fera, Frontier, ADAS, AHDB, Agrii, Bayer CropScience, Stockbridge Technology Centre and Newcastle University. The data collected will be used to ensure the outputs from new risk models being developed are reliable and robust.  

Latest results from Defra national wheat survey 01 Nov 2017
Results are now available from the latest survey of diseases of winter wheat carried out in July 2017. Septoria tritici remained the most common foliar disease affecting 81% of crops, the highest incidence since 2014. Levels of brown rust increased compared to previous years whereas yellow rust incidence was equivalent to the long-term average. Brown rust affected 11% of crops, the highest incidence since 2012 whereas disease severity was the highest since 2007. Powdery mildew affected 24% of crops and was the second most common of the main foliar diseases. Mildew levels have declined in recent years but this was the highest incidence since 2011.  

Latest results from Defra national oilseed rape survey 01 Nov 2017
Disease levels in oilseed rape were generally lower than the long-term averages. Light leaf spot incidence was particularly noteworthy as levels were significantly lower than in 2016, when the highest incidence of light leaf spot was recorded since the survey began in 1987.  

What's new

01 November 2017: Our latest reports from the national monitoring of diseases in winter oilseed rape and winter wheat in summer 2017 are now available.

01 November 2017: CropMonitor is currently being extended and updated to form the core platform for a new national capability in decision support which is a part of the Crop Health and Protection Centre (CHAP). Supported through investment from Innovate UK, the first phase of the new system will be launched in the spring and will be accessed through the usual CropMonitor web address. This new capability, the SMART Decision Support Unit, will deliver risk forecasts for pests and diseases of wheat, barley, oilseed rape and potatoes using a bespoke weather monitoring network, national surveillance data and new risk models. Until we launch the new website you will continue to see the map on the live monitoring pages which will show all the new monitoring locations for 2017/18 and a table alongside showing current risk forecasts for foliar diseases of wheat.
