Alternaria monitoring indicates application timing

Written by Charlotte Cunningham from CPM Magazine

Results of last season’s Syngenta alternaria monitoring in potato crops has further reinforced the pattern of earliest infection from A. alternata, with A. solani typically coming into crops later in the season. Charlotte Cunningham reports. The monitoring is undertaken by independent and industry potato agronomists sampling suspected cases throughout the season, with laboratory analysis by NIAB specialists to determine the species of alternaria (early blight) present. Up until a sampling date of 23 July (2020), 85% of the positive alternaria infections identified were only A. alternata, with 15% A. solani and only at low levels. From 24 July, however, 81% of samples contained A. solani and just 9% solely A. alternata. Around 20% of samples tested had mixed A. alternata and A. solani identified as present. No A. alternata was identified in the sampling after 9 August. While AHDB advice points to A. solani being the dominant early alternaria species, annual in-field monitoring has again shown it has been the A. alternata coming in first. Syngenta technical manager, Michael Tait, highlights the information is particularly valuable to highlight the timing of onset for alternaria infections and in assessing agronomy options. “Alternaria leaf spots can result in rapid loss of green…

Update on the Sustainable Farming Incentive pilot

Written by Lisa Applin

In July, we opened the applications window for farmers to join our Sustainable Farming Incentive pilot.

The Sustainable Farming Incentive is 1 of the 3 new environmental land management schemes. It sits alongside the future Local Nature Recovery and Landscape Recovery schemes.

Through the Sustainable Farming Incentive, farmers will be paid for environmentally sustainable actions – ones that are simple to do and do not require previous agri-environment scheme experience.

We are piloting the scheme to...
