October has been a mild month to date with plenty of disease pressure and as always there has been plenty of questions about which fungicide to use. These milder periods inspired me to put this blog together looking at how the temperatures look when you break them down into hourly chunks. I put this together…
Month: October 2021
Has October 2021 been a cold one?
One of the things Henry and myself have been chatting about “On the Horizon” is the concept of sub 2c stopping hours. It’s a concept we’ve developed to help us understand when we start to see weather that is cold enough to slow down the development of Microdochium patch and how variable it is across…
Late Cranefly emergence
After the heavy rainfall this weekend I had several course managers reporting a late emergence of Cranefly just when they thought it was all over!

Ok lets start at the beginning, any Acelepryn purchased under the Emergency Authorisation for Cranefly in 2021 must be used by the 29th…
FR321 Latest trial data
A trial at STRI this year looking at the use of FR321 in integrated programmes designed to combat Anthracnose. As we creep into the Autumn period and the Microdochium pressure I felt the benefits we’ve seen in this trial of FR321 in controlling this problem would be worth sharing. The trial in question was put…
