Wheat T1s are a priority at the moment, but evenness of emergence of the third leaf is a bit out of sync, with many crops not receiving a TO and applications delayed on others.It’s worth exercising patience to cover as many target leaves as possible for the best results.
Septoria pressure is rather enormous in some crops, especially those that were drilled early and received no TO. Products in the main are based on SDH1s, primary azoles and a multisite.
The only yellow rust to be found has been in Lili and Diego, as growers were unable to treat them before T1.
The spell of hot weather in mid-April has motored plant growth on. I’ll be using the fast-acting plant growth regulator prohexadione, in many instances, on crops racing away.
Oilseed rape has illuminated the fields and will be receiving some supplementary foliar amine nitrogen along with their fungicides. The canopy is built, so we are now focusing on longevity to fill seeds to their potential.
Amine N is a very safe and energy-efficient way of achieving this and will provide a phased release of N over the coming weeks.
Combinable crop drilling has been a steady affair, but should now be coming to an end. Potato plantings are also getting late, but some of the earlier plantings are now beginning to receive their residual herbicides. I'm confident with current conditions they will be applied to moist, settled ridges, with another shower to finish the job off.
Muck stores are almost empty, but maize drills are only just getting going. Some fields had a hard time over the winter, with little opportunity for access without soil damage.
As such there is likely to be many variable crops across the county as cultivations for any depth of compaction are unlikely to be carried out. This highlights the need for soil management on continuous maize fields straight after harvest.
If the crop isn’t undersown, a light cultivation will make a huge difference to the infiltration of rainfall over winter, reducing the risk of soil erosion on these often light and overly phosphorous-enriched soils.
