Regional Crop Report East Midlands,   27 April 2007
Winter Wheat
Comment on current growth stages Field conditions
Most crops at leaf 2 with odd ones showing flag leaf tip. Backward crops have leaf 3 emerged. Big decision will be on T2 timing - it could be a long time from T2 until harvest depending on how May and June turn out, which puts a T3 spray more likely than in many seasons, especially on dirtier varieties. Some rain (about 6 mm), only 3 mm rain in 6 weeks in some areas, has helped a bit but not enough if weather warms up again. Continued dry weather is resulting in plant tiller numbers reducing while crop is making slow growth. Soils generally dry and rain has not penetrated any clods. Second split of main N due to go on but farmers have been holding back in dry weather until some moisture to take it in. Granules from earlier applications still on the ground.
Main diseases Present Level and comment
Brown Rust Not a problem so far.
Mildew Levels very low.
Septoria tritici T1 spray now on most crops and - leaves 4 and 5 are clean due to chlorothalonil at T0 and dry weather.
Yellow Rust Only present in Robigus - there is a big question mark over the future of Robigus amongst farmers.
Eyespot Very little seen.

Main Pest problems Level and comment
Aphids None seen
Frit fly None seen
Leatherjacket None seen
Opomyza None seen
Slugs Slugs grazing top leaves but not damaging. A lot of slime trails about in spite of the dry.
Wheat bulb fly None seen
Wireworm None seen

Blackgrass No further treatment.
Meadow grasses No further treatment.
Rye grass No further treatment.
Bromes No further treatment.
Cleavers Apart from one or two crops many have low levels, which will be mopped up at T2.

Winter Barley
Comment on current growth stages Field conditions
Awns now showing in forward crops, some 2 weeks earlier than usual. Crops not all that tall so dubious as to whether a late growth regulator is required in many cases. Some rain (about 6 mm), only 3 mm rain in 6 weeks in some areas, has helped a bit but not enough if weather warms up again. Continued dry weather is resulting in plant tiller numbers reducing while crop is making slow growth. Soils generally dry and rain has not penetrated any clods. Second split of main N due to go on but farmers have been holding back in dry weather until some moisture to take it in. Granules from earlier applications still on the ground.
Main diseases Present Level and comment
Brown Rust None seen
Mildew No new pustules.
Net blotch New growth remains clean.
Yellow Rust None seen
Eyespot None seen
Rhynchosporium Very low levels.
Other BYDV patches starting to appear in early sown crops that had only one autumn aphicide.

Winter Oilseed Rape
Comment on current growth stages Field conditions
Crops well forward with many crops at mid to late flowering - up to 50 pods on some racemes. Flowering could well be coming to an end some 2-3 weeks earlier than usual as temperatures pick up again. Odd cases where lower petals show sulphur deficiency even when sulphur N applied. Probably due to N (and Sulphur) not being taken up quickly enough in the dry as a lot lay on the surface for some time. All nitrogen applied 2/3 weeks ago, but poor uptake. Some crops look starved, and some Bastille and Amstrad very short. Some rain (about 6 mm), only 3 mm rain in 6 weeks in some areas, has helped a bit but not enough if weather warms up again. Soils generally dry and rain has not penetrated any clods.
Main diseases Present Level and comment
Club root No further reports.
Downy Mildew No longer of concern.
Light Leaf Spot None seen
Phoma None seen
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 Mealy aphids found on some crops - numbers are low but some racemes heavily infected - this is usually a late season problem which generally needs no control measures but worrying that they are in early this year. Crops will be monitored for build-up, but as crops are well into petal fall then hopefully will not be a problem.
Main weed problems Level and comment
Blackgrass None seen
Meadow grasses None seen
Rye grass None seen
Bromes None seen
Cleavers None seen
