Regional Crop Report Eastern Counties ,   13 April 2007
Winter Wheat
Comment on current growth stages Field conditions
Mid September drilled Alchemy, Robigus and Solstice at GS 32 with late October drilled Gladiator at GS 29/30. Earlier N doses being picked up despite dry and crops generally quite green but large number of crops showing effects of earlier boggy conditions with reduced tillering. Disease levels much reduced. No rain for a month, soil surface like concrete with cracking all caused by 'final straw' February rain and subsequent dry.
Main diseases Present Level and comment
Brown Rust Disappeared.
Mildew Much less evident.
Septoria tritici No increase - lower leaves on most varieties have the disease.
Yellow Rust Essex: trace in some Robigus crops with very occasional Foci. Norfolk: sight increase over last week on Robigus.
Eyespot Essex: Generally dry weather has halted the 'march' of the disease. Little penetrating lesions. Will advent of wetter weather increase risk?
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.

Winter Barley
Comment on current growth stages Field conditions
GS 30 with some at GS 31 which will get T1 shortly. Disease levels, particularly rhynchosporium, lower than normal. No rain for a month, soil surface like concrete with cracking all caused by 'final straw' February rain and subsequent dry.

Eyespot None seen.
Rhynchosporium Very low
Other None seen.
Main Pest problems Level and comment
Aphids None seen.
Leatherjacket None seen.
Slugs None seen.
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

Winter Oilseed Rape
Comment on current growth stages Field conditions
Still large differences in plant height within a field. Castille most forward approaching full flower, a few pods set on most forward plants. Planning flowering sprays for Sclerotinia control currently risk is diminishing. Will review need to spray next week taking into account weather forecast especially for rainfall. No rain for a month, soil surface like concrete with cracking all caused by 'final straw' February rain and subsequent dry.
Main diseases Present Level and comment
Club root None seen.
Downy Mildew None seen.
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 None seen.
Main Pest problems Level and comment
Aphids None seen.
Flea beetle None seen.
Leatherjacket None seen.
Slugs None seen.
Other Pollen Beetle: only odd backward crop or area merited treatment.
Main weed problems Level and comment
Blackgrass None seen.
Meadow grasses None seen.
Rye grass None seen.
Bromes None seen.
Cleavers
