Another Monday, another blanket of snow

I was down in Dorset scheduled to go crop walking but when you look out of your window and see the snowy blanket, it’s definitely the sort of day to spend playing with your two-year old niece instead.

Wednesday was a better day, going round some Northamptonshire farms. Some of the wheat was starting to wake up, especially some of the earlier drilled Skyfall. Where this was lush, mildew was evident but, in general, disease levels were low across the varieties we looked at.

T0 sprays are being planned for some early sown forward wheat crops, although they will be a few weeks away on the crops we looked at, even the most forward.

 

With people planning sprays soon, I thought I’d look at a publication we produced as part of the Fungicide Futures initiative earlier this year. It looks at fungicide resistance in septoria tritici. Q&A number nine relates to T0 sprays.

 

  1. Can using an azole at T0 to control yellow rust make septoria tritici more resistant to azoles?
  2. Yes – Selection for azole-resistant strains happens whenever an azole is used, even if septoria tritici is at low levels and is not the target of the spray. If rust is the main target, a strobilurin is a good alternative.

We need to protect efficacy. And our fungicide choices need to be driven by the long-term implications of our collective actions…

OSR is starting to extend but some crops have clearly suffered from the recent fluctuations in temperature, with distinct curling of the leaves. But this is nothing it can’t handle and it should easily grow away.

Until next time…if I regain the use of my legs. 20km through muddy fields, trying to keep up with an agronomist, is not something an office job prepares you for!
