Regional Crop Report South East,   18 May 2007
Winter Wheat
Comment on current growth stages Field conditions
September and early October sown crops now commonly range between GS 49-52 (Claire/Alchemy) up to GS 55+ (late September sown Xi19/Einstein). All late September and early October sown crops of Einstein, Xi19 and Solstice now have ears around 1/3-fully emerged. All crops of Soissons are now flowering. Soils are at long last damp again following around 2.5-3 inches of rain in the last 10 days (first proper rain for 7 weeks).
Main diseases Present Level and comment
Brown Rust Still widespread on lower leaves all September sown crops of Alchemy, Solstice and Claire in particular, with active pustules increasingly evident on lower leaves (particularly leaves 4 and 5, but also odd pustules now appearing on leaf 3 of thicker crops) of crops where last fungicides applied around 2-3 weeks ago.
Mildew Still very hard to find any active pustules.
Septoria tritici Very little evidence of Septoria in many crops from leaf 4 and above, even in Malacca/Solstice.
Yellow Rust So far under control from fungicides already applied.
Eyespot A few very early drilled Solstice (18-22 September) crops have such severe penetrating eyespot on main shoots, that in some cases these are already lodging.
Other BYDV - noticeable patches of severe virus showing in many mid-late September sown wheat crops along high-risk coastal belt, despite use of Deter and follow-up pyrethroid in November.

Winter Oilseed Rape
Comment on current growth stages Field conditions
All crops have now finished flowering and with a good pod set and hopefully a long pod-filling period sustained by late N uptake and rain at last, yields should be respectable.
Soils are at long last damp again following around 2.5-3 inches of rain in the last 10 days (first proper rain for 7 weeks).
Main diseases Present Level and comment
Club root No further reports.
Downy Mildew None seen.
Light Leaf Spot None seen.
Phoma None seen.
Powdery Mildew Just beginning to find first signs of infection developing, particularly in Recital. With damp soils, increased humidity, and a 4-6 week interval since last fungicides applied, will need to be vigilant and if necessary apply fungicide for control.
White Leaf Spot None seen.
