Regional Crop Report North East ,   13 April 2007
Winter Wheat
Comment on current growth stages Field conditions
Week before had cold days and nights, which slowed crop development. It is much warmer now and generally crops are growing well again with some early sown close to GS 32. Only limitation is long dry spell, which is slowing N uptake and in some seedbeds also restricting root development. Most first wheats showing loss of colour due to N deficiency.
Main diseases Present Level and comment
Brown Rust Mostly disappeared now after early attack.
Mildew As with Brown rust it has mostly disappeared now after early attack.
Septoria tritici Present in all crops with all susceptible varieties showing significant level.
Yellow Rust Trace levels in some crops of Robigus.
Eyespot Some stem discolouration easy to find in most early sown crops. Some stem penetration reported in area.
Other None seen
Main Pest problems Level and comment
Aphids None seen
Frit fly None seen
Leatherjacket None seen
Opomyza None seen
Slugs Later crops in poor seedbeds are still being watched.
Wheat bulb fly None seen
Wireworm None seen
Other Gout Fly - moderate levels can be found in all crops sown before the end of September.
Main weed problems Level and comment
Blackgrass No new problem areas seen yet this year but still have some herbicide to apply that was recommended in December.
Meadow grasses Emerging in unsprayed fields.
Rye grass Low levels emerging. Some crops have been treated Peri or early Post emergence where spraying was delayed.
Bromes Becoming obvious in some fields.

Winter Barley
Comment on current growth stages Field conditions
Most crops at GS 31. Very dry now. Crops taking up N but some rainfall would help. Only limitation is long dry spell, which is slowing N uptake and in some seedbeds also restricting root development. Most first wheats showing loss of colour due to N deficiency.
Main diseases Present Level and comment
Brown Rust None seen
Mildew Much lower level now following long dry spell and appearance of new growth.
Net-blotch Significant level in Carat and Pict, but Saffron only very low level.
Yellow Rust None seen
Eyespot None seen
Rhynchosporium None seen
Other None seen
Main Pest problems Level and comment
Aphids None seen
Leatherjacket None seen

Meadow grasses
Rye grass Moderate - Low levels emerging.
Bromes
Cleavers
Others

Winter Oilseed Rape
Comment on current growth stages Field conditions
Crops flowered very quickly over Easter weekend and most crops now overall yellow. Some have patches where late to flower and a few crops still only at yellow bud stage. Final N applications applied last week just before crops tall enough to spoil spreading pattern.  
Main diseases Present Level and comment
Club root None seen
Downy Mildew None seen
Light Leaf Spot Some signs of new infection.
Phoma No reinfection seen.
Powdery Mildew None seen
White Leaf Spot None seen
Other Sclerotinia: this is a high-risk area due to short rotation and very high acreage of rape over may years. Despite dry conditions will apply fungicide when 10 - 20 pods set on main stem, say in 10 - 14 days.
Main Pest problems Level and comment
Aphids None seen
Flea beetle No larvae been found.
Leatherjacket None seen
Slugs None seen
