RAPID ACCESS TO THE LATEST REGIONAL CROP PEST AND DISEASE LEVELS 		HGCA logo
 


Regional Crop Report Eastern Counties,  30 March 2007
Winter Wheat
Comment on current growth stages Field conditions
Most advanced between GS 30 and 31 - Robigus and Alchemy. Disease levels less with many older leaves dried up. Effects of three very wet months showing up in poor growth in patches in many fields - generally 'min till' worst affected and second wheat worse than first but this is mainly down to timing of cultivation and drilling, notably using heavy equipment on wet soil. Soil surface drying up.
Main diseases Present Level and comment
Brown Rust Still visible on forward Alchemy, Einstein and Solstice but no increase on last week.
Mildew Much less evident.
Septoria tritici No increase - lower leaves on most varieties have the disease - so what's new! Alchemy cleanest followed by Robigus. Clear pattern in disease levels with drilling dates - late October drilled crops almost completely clean.
Yellow Rust Essex: Robigus showing few pustules on some crops. Norfolk: none seen.
Eyespot Essex: at up to 10% level in early drilled Robigus, Solstice and Gladiator. Norfolk: low level in second wheats.
Other None seen.
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.
Other  
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.

Other None seen.

Regional Crop Report Eastern Counties,  30 March 2007
Winter Oilseed Rape
Comment on current growth stages Field conditions
Crops at green to yellow bud stage with a few fields coming into flower. Great variability still from field to field. Also quite a lot of variability in height of plants within a field. Crops improving all the time as they take up N. Crop heavy with dew in mornings so have been waiting for it to dry before applying solid N. Second N dose now being applied to most advanced crops and planned for the remainder soon. Spindly, poor crops have received trace elements Boron, Magnesium, Manganese. Growth regulatory fungicides being applied to several forward crops this week. Soil surface drying up.
Main diseases Present Level and comment
Club root None seen.
Downy Mildew Crops now beyond stage where this disease is a problem.
Light Leaf Spot Odd foci of light leaf spot seen on variety Castille in several fields in west Norfolk
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 Larvae in leaf stems is more obvious than in previous years.
Leatherjacket None seen.
Slugs A lot of slug grazing on lower leaves.
Other Pollen Beetle: few present on sunny afternoons this week but nowhere near threshold levels.
Main weed problems Level and comment
Blackgrass Treatments have been disappointing in many fields.
Meadow grasses Limited problem as most fields received pre-em herbicide.
Rye grass Rapid growth in untreated fields.
Bromes Rapid growth in untreated fields.
Cleavers
Others
