Regional Crop Report Eastern Counties,   27 April 2007
Winter Wheat
Comment on current growth stages Field conditions
Crops mainly at GS32 with a few forward crops at GS 37. T0 and T1 sprays seem to be holding the rusts. Some wheat, particularly later drilled showing drought stress. Both yellow and brown rust are prevalent on susceptible varieties, on Robigus it has taken around 7 - 10 days for the 'T1' mix to clean up existing infections. Very dry and hard. No rain since 19th March in some areas of Norfolk. Essex very dry no rain for 4 weeks.
Main diseases Present Level and comment
Brown Rust Is active on a number of varieties, Alchemy worst affected with disease readily seen on leaf 5 and creeping onto leaf 4 in some crops, must be carefully watched. At the current rate of progress on some early fields, flag leaf spraying may commence from around 10th May.
Mildew Treatable levels and spreading up on Solstice.
Septoria tritici No increase - lower leaves on most varieties have the disease.
Yellow Rust There are obvious foci in some crops of Robigus, developing quickly if untreated. Yellow patches seen from a distance on some fields.
Eyespot At low levels.
Other Take-all there are telltale patches beginning to develop on some fields of second wheat. These effects would appear to have been exaggerated by the lack of moisture moving N into the crop over the last two months. Monitor these areas, and make necessary economies in terms of fungicides + other inputs where possible.

Winter Oilseed Rape
Comment on current growth stages Field conditions
Crops all in full flower, earliest now at petal fall with 20 + pods set on main raceme. Crops generally very short. Very dry and hard. No rain since 19th March in some areas of Norfolk. Essex very dry no rain for 4 weeks.

Light Leaf Spot In the East foci stopped spreading in dry conditions, not perceived to be a problem.
Phoma No new infection.
Powdery Mildew None seen.
White Leaf Spot None seen.
Other Sclerotinia- still holding off on decision on flowering fungicide on low risk sites. Other fields have been sprayed.
Main Pest problems Level and comment
Aphids None seen.
Flea beetle None seen.
Leatherjacket None seen.
Slugs None seen.
Other Seed weevil activity starting in warm weather. Will include an insecticide in some mid flowering sprays.
Main weed problems Level and comment
