Clear differences here in the longveity of different products on keeping #Septoria at bay, which in mid-june could be very difficult to seperate out. Extending that GLA duration key to capturing as much of that yield building sunlight as possible. @BASFcropUK

Knowing how best to manage fungicide resistance 🌾 can be confusing. This handy slide shows: ✔️Add mixture partner ✔️Alternate actives ❌Increase dose ❌More sprays ❌Split dose

Jonathan focuses first on wheat: new product Revystar XE is very effective on Septoria tritici & brown rust, while Elatus Era is effective on brown rust. Against Fusarium Soleil & Proline are effective while SDHI/azoles showed good level of control on mildew #AgConf19

Impressive tap root length on autumn treated Caryx plants. Follow up spring application vs untreated to see if it’s worth doing or not!

Not to be missed! #CropFocusTV episode 3 features @RealFarmerPrice discussing #blackgrass control, nutrition, how he uses the @yara N Sensor and #Brexit. @Gilesy256 & @jon_helliwell ask the questions! cropscience.bayer.co.uk/blog…

Septoria on the tips of the last leaf to emerge in this Lilli in Lincs. This short latent period must be balanced by either a lower than average infection efficiency or low sporilation for it to be considered one of the ‘less susceptible’ on the RL.

So many talks at #EGU18 using X-ray Computed Tomography in soil and plant sciences. Fantastic to see the growth of the community @UoNHounsfield

Bees and neonics. Viewpoint: Two-year review of research highlights need for more detailed investigation, and before more pest controls are tarred with the same brush. @EFSA_EU

Same variety at our Callow demo today, only difference is 10 days between drilling dates. Same disease pressure?

With a forecast wet few days ahead and plenty of rainsplash potential has the Septoria fuse been lit ? Ascra Xpro is the ideal T2
