RAPID ACCESS TO THE LATEST REGIONAL CROP PEST AND DISEASE LEVELS
Regional Crop Report North East, 11 May 2007
Winter Wheat
Comment on current growth stages
Field conditions
All first wheats have flag leaf fully emerged, GS 39, and the later
sown second and continuous crops at early flag leaf emergence GS 37.
Yet another dry week with no rainfall recorded, but has just started
raining this evening. A proper wet day would be of great benefit to
all crops now, although only slight drought symptoms on free draining/light
land can now be detected. Crops are well grown but most a bit shorter
than usually so a late PGR is being applied at lower rates this year.

Control
by T1 fungicides has been good, but there are still some spores on
lower leaves in Alchemy, Nijinsky, and Claire. Present but lower level
on Robigus. Worst affected crops have been dense early sown crops.
Infection reached upper leaves in areas of double drilling and fertilising
and rest of field stayed very clean. No intermediate treatments made

increase on light land
