Regional Crop Report Eastern Counties,   20 April 2007
Winter Wheat
Comment on current growth stages Field conditions
Crops largely GS 31/32. Late drilled at GS 30. Few at GS 32/33. T1 going on now. T0 on late crops of Robigus for Y.Rust. Applied N uptake poor in dry conditions on lighter land. In middle of T1 sprays. Field conditions: very dry and hard. No rain since 19th March in some areas of Norfolk. Essex reports that it is very dry, but plants are picking up N and most crops are respectably green.
Main diseases Present Level and comment
Brown Rust Resurgence of disease on Solstice, Alchemy and Robigus mostly confined to lower leaves but creeping up on some crops.
Mildew Treatable levels and spreading up on Solstice.
Septoria tritici No increase - lower leaves on most varieties have the disease.
Yellow Rust Spreading upwards on Robigus. Many fields affected.
Eyespot at low levels.
Other The dry should have reduced take-all risk, although it will not have eliminated inoculum that has built up particularly on the less well structured soils.
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.
