Regional Crop Report Eastern Counties,   16 March 2007
Winter Wheat
Comment on current growth stages Field conditions
Most advanced between GS 30 and 31 - Robigus and Alchemy - Gladiator on similar drill date now at GS 30 and Claire GS 29. Early growth regulator being applied to early drilled crops of Alchemy and Robigus. N being applied to second wheat. The indications from mineral nitrogen surveys, in the region, are that soil reserves are below the average figures compared to the last few years. Drying up nicely on the surface.
Main diseases Present Level and comment
Brown Rust Easily found at low level on forward Alchemy and Solstice.
Mildew Essex: new leaves clean and older leaves now dying back giving less disease than month ago. Norfolk: increasing levels with high levels on Robigus on Black Fen soils.
Septoria tritici No increase - lower leaves on most varieties have the disease - so what's new! Alchemy cleanest followed by Robigus. Clear pattern in disease levels with drilling dates - late October drilled crops almost completely clean.
Yellow Rust Essex: Trace in forward crops of Robigus. Norfolk: none seen.
Eyespot Essex: at up to 10% level in early drilled Robigus, Solstice and Gladiator. Norfolk: low level in second wheats.
Other None seen.
Main Pest problems Level and comment
Aphids No fresh sightings reported.
Frit fly None seen.
Leatherjacket None seen.
Opomyza None seen.
Slugs None seen.
Wheat bulb fly None seen.
Wireworm None seen.

Main weed problems Level and comment
Blackgrass A few fields unsprayed require treatment as soon as posible..
Meadow grasses Treatments working.
Rye grass Tillering in untreated crops.
Bromes No fresh sightings reported.
Cleavers Now endemic.
Others Wild Oats: first signs of emergence, over-wintered wild oats approaching second node.

Winter Barley
Comment on current growth stages Field conditions
Largely GS 30. Many crops very yellow due to water logging or mildew. Drying up nicely on the surface.

Brown Rust None seen.
Mildew Norfolk: moderate to high levels seen.
Net-blotch Levels vary from trace to significant levels on some crops.
Yellow Rust None seen.
Eyespot None seen.
Rhynchosporium None seen.
Other None seen.
Main Pest problems Level and comment
Aphids High risk in untreated crops.
Leatherjacket None seen.
Slugs Most crops beyond stage where damage is of importance.
Wireworm None seen.
Other None seen.
Main weed problems Level and comment
Blackgrass Few fields still need follow-up. Wet conditions has prevented spraying.
Meadow grasses Low levels so far.
Rye grass High level in a few fields.
Bromes High level in a few fields.
Cleavers
Others

 
Regional Crop Report Eastern Counties,   16 March 2007
Winter Oilseed Rape
Comment on current growth stages Field conditions
Crops rapidly beginning to go through stem extension. On some lighter fertile sites crops are already 18" + tall with flower buds well above the crop. There is an enormous variation in growth between crops, mainly depending on recent N uptake by crop, inherent fertility of site and rooting depth and extent of crop. Planning canopy management fungicide applications, which some tall thick crops will require very soon. Other crops are still some way off and will need to be reviewed. Drying up nicely on the surface.
Main diseases Present Level and comment
Club root None seen.
Downy Mildew Crops now beyond stage where this disease is a problem.
Light Leaf Spot Odd foci of light leaf spot seen on variety Castille in several fields in west Norfolk
Phoma No new infection.
Powdery Mildew None seen.
White Leaf Spot None seen.
Other None seen.
Main Pest problems Level and comment
Aphids None seen.
Flea beetle Larvae in leaf stems is more obvious than in previous years.
Leatherjacket None seen.
Slugs A lot of slug grazing on lower leaves.
Other None seen.
Main weed problems Level and comment
Blackgrass Treatments have been disappointing in many fields.
Meadow grasses Limited problem as most fields received pre-em herbicide.
Rye grass Rapid growth in untreated fields.
Bromes Rapid growth in untreated fields.
Cleavers
Others
