Regional Crop Report East Midlands,  30 March 2007
Winter Wheat
Comment on current growth stages Field conditions
Very little forward movement as crops mark time - the cold weather last week virtually stopped growth and this week the ground frost at night and cool foggy mornings have not helped although there have been warm afternoons. Most crops at GS 30 with forward ones close to GS 31. Later crops at GS 29-30. Soils very dry on top but like plasticine below top inch or so. Good travelling conditions.
Main diseases Present Level and comment
Brown Rust Traces on Alchemy, Cordiale and Einstein.
Mildew Last week's cold and cold nights this week is holding mildew down and is almost non existent, even on forward thicker crops.
Septoria tritici Usual lesions on older leaves but top leaves clean so far.
Yellow Rust Traces on Robigus.
Eyespot Levels remain low even in 2nd wheat - helped by drying conditions with bases of plants very dry and older leaf dying off. Even where found on older leaves there is no penetration. Odd lesions can be found up the stem but again not penetrating.

Winter Barley
Comment on current growth stages Field conditions
Generally GS 30-31 but some crops still showing signs of stress and need to put on some new leaf. Light land crops taking a while to respond to first nitrogen applications. Soils very dry on top but like plasticine below top inch or so. Good travelling conditions.
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 New growth remains clean
Yellow Rust None seen
Eyespot None seen
Rhynchosporium Becoming more obvious
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,  30 March 2007
Winter Oilseed Rape
Comment on current growth stages Field conditions
Crops very variable - forward crops starting to flower but some later crops slower developing - cold of last week has had an effect with some crops till showing "drooping" flower buds where wind and frost has bent them over. Recent night frosts haven't helped. All crops have had first N and remainder to go on in about 10 days - aim is to leave until last possible moment when able to travel through the crop. Soils very dry on top but like plasticine below top inch or so. Good travelling conditions.
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 Pollen beetle levels remain low after the cold - backward thinner crops will have to be monitored carefully for pollen beetle damage as day temperatures rise giving increased numbers - however some rape flowering in forward crops.
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
