Regional Crop Report East Midlands,   23 March 2007
Winter Wheat
Comment on current growth stages Field conditions
Very little change due to cold weather. Most crops at GS 30 with forward ones close to GS 31. Later crops at GS 29-30. Stress symptoms persist ranging from yellow, due to wet feet, to some purpling of leaves from recent cold winds. A lot of lower leaves have died off now with in some cases the odd tiller dying - probably due to wet feet followed by drying winds. N going on stressed crops and where tiller numbers need to be held. Soil temps have dropped to less than 4 deg C in last couple of days. Forward crops have had a growth regulator - later crops (or rather more normal crops for time of year) will have chlormequat next week. Soils on top now dry and travallable but wet patches remain and soils below surface very wet and sticky.
Main diseases Present Level and comment
Brown Rust Traces on Alchemy, Cordiale and Einstein.
Mildew Some on older leaves of Solstice but not very active and colder weather is holding it.
Septoria tritici Usual lesions on older leaves but top leaves clean so far.
Yellow Rust Traces on Robigus.
Eyespot Levels remain quite low so far with leaf tissue dying off and base of plants drying out. Solstice so far has the highest level but no more than 2-3%.

Winter Barley
Comment on current growth stages Field conditions
Moved very little over past two weeks and still at GS 30, in fact some crops have moved back a bit as wet soils has stressed them. Soils on top now dry and travallable but wet patches remain and soils below surface very wet and sticky.
Main diseases Present Level and comment
Brown Rust None seen
Mildew At very low levels so far on lower leaves but keep becoming obvious in crops of Saffron.
Net-blotch Odd lesions but Carat particularly bad.
Yellow Rust None seen
Eyespot None seen
Rhynchosporium Rhynchosporium just starting to appear.
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 Not a problem where barley this year so no pre-ems.
Meadow grasses On the whole crops remain clear.
Rye grass
Bromes
Cleavers
Others

 
Regional Crop Report East Midlands,   23 March 2007
Winter Oilseed Rape
Comment on current growth stages Field conditions
Crops at mid to late green bud, with odd bolter in flower. Cold winds followed by -3.50C overnight has caused flower buds to bend over, but should recover OK when temps go up. Many crops have GAI of 2+. Will also receive some boron on some farms where history of low boron or broad spectrum soil analysis has shown very low levels. Soils on top now dry and travallable but wet patches remain and soils below surface very wet and sticky.
Main diseases Present Level and comment
Club root Crops growing away but stunted - small patches being compensated by plants around them. Patches will be mapped and then receive lime, on the patches, in the next wheat crop. Also boron going on where club root found, even if small patch.
Downy Mildew No longer of concern.
Light Leaf Spot None seen
Phoma All sprayed crops show no new infection with new growth clean.
Powdery Mildew None seen
White Leaf Spot None seen
Other Lioness may need some magnesium, but so far not as bad as last year for magnesium deficiency, probably due to mild weather in March and good growth.
Main Pest problems Level and comment
Aphids None seen
Flea beetle  
Leatherjacket None seen
Slugs Most crops now past any risk apart from odd backward patches.
Other Odd pollen beetle seen before cold weather but none seen since.
Main weed problems Level and comment
Blackgrass Residual herbicides still to be applied on some fields - cut off is end of January.
Meadow grasses
Rye grass Localised problem only.
Bromes
Cleavers
Others
