The dry weather has kept disease development subdued and the majority of crops are looking clean with large green flag leaves doing their job.
Mildew that was about earlier in the season has failed to move and if it is in a crop it is low down in the canopy and at low levels. Still worth keeping an eye on though as it can move quickly if weather changes.
The dry weather is just starting to stress plants particularly in the middle of the day when heat and light intensity mean transpiration rates exceed water uptake rates and the stomata close down in order to regulate water loss.
Harvest estimates at this stage are still good.
