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. All data gathered are being analysed to identify disease and pest risk, seasonal variation in disease development and the effectiveness of control strategies. Users will be alerted to emerging threats during the growing season and advised on appropriate courses of action.

South East (11 samples) – average per plant is 6.8, 7 beetles per plant threshold exceeded at 5 sites, 11 beetles per plant exceeded at 4 sites, no other thresholds exceeded but two sites approaching 18 beetles per plant threshold.  

Spring Survey confirms high year for Cabbage Stem Flea Beetle 31 Mar 2014
The spring survey of OSR confirms that it is a high year for CSFB, particularly in the East and South West. No regions had an average of >5 larvae per plant. However, the 5 larvae per plant threshold was exceeded at one site in the East. The 2 larvae per plant threshold has been exceeded at 1 site in the East and 1 site in the South West.  

Light leaf spot - second most severe year on record 25 Mar 2014
Mild weather conditions during the winter and early spring have affected disease levels in spring 2014, with all diseases occurring at higher levels than last year. Results from the Defra survey show that light leaf spot was the most prevalent disease recorded this spring, affecting 87% crops and 44% plants in the survey compared to the long-term mean (2003-2012) of 50% crops and 17% plants affected. Disease incidence was highest in the North (100% crops surveyed were affected) and lowest in the South West (70% crops affected).
