RAPID ACCESS TO THE LATEST REGIONAL CROP PEST AND DISEASE LEVELS
Regional Crop Report West Midlands, 18 May 2007
Winter Wheat
Comment on current growth stages
Field conditions
Most wheats at full flag apart from January sown crops which have leaf
2 out. Gladiator has raced ahead this last week and has caught up
with Einstein both of which have the ear half way out. Alchemy has
come to a dramatic stop with just the early September crops at booting.
What
a difference a week makes, we have had somewhere between 3.5-4.5
inches of rain, majority of fields will travel with row crops when spraying
conditions are OK (few and far between at the moment what with showers
and high winds). Very few proper T2 fungicides have been applied due
to the poor conditions, most crops are now at 3 weeks from T1 with
some at 4 weeks. Majority of crops will end up with a T2/T3 combined.
Some signs of root lodging on big crops of wheat due to very heavy
rain, high wind and very wet soil.
