High potential for Sclerotinia threat this season
Many fields that grew rape in 2007 or 2008 have been cropped with oilseed rape this year and very high levels of disease then will mean the potential innoculum source could be very high now, warns ProCam UK Agronomy Manager, Nick Myers. We know that you only need very few sclerotia in the soil to […]
New recommendations for weed control in potatoes
Weed control has been more challenging over the last two seasons and in response Scottish Agronomy have been trying new techniques with growers and conducting trials to find the way forward. Scottish Agronomys Eric Anderson cites annual meadow-grass, black-bindweed, cleavers, fumitory, knotgrass and volunteer oilseed rape as weeds that now demand a more considered approach. […]
ADAS/BASF Sclerotinia monitoring indicates the start of sclerotia germination and disease risk
The ADAS/BASF web-based monitoring service on www.totaloilseedcare.co.uk is reporting the start of sclerotia germination, with 12% germination detected in Devon. This, together with apothecia being found near to the site in Herefordshire, indicate that the pressure is on to start protecting the oilseed rape crop from damaging Sclerotinia infection. Jon Williams, Agronomy Manager for BASF, […]
Post-emergence control for weed competition in peas
Continued dry weather conditions will compromise the efficacy of pre-emergence herbicides in peas this season, where the emerging crop is especially susceptible to weed competition for moisture and available nutrients. Syngenta Specialist Crops Manager, Bruce McKenzie, highlights that the herbicide, Skirmish, has the added flexibility of pre and post-emergence application in peas, right through to […]
Becky Ward, PGRO senior technical officer, advises:
Pea and bean weevil There is now significant pea and bean weevil damage to spring beans and some winter bean crops. Where damage is becoming obvious, an insecticide should be applied as soon as possible and repeated after 2 weeks. This will help to disrupt the egg laying period and reduce the potential for larval […]
Robust PGR use essential to maximise crop value.
With most growers setting out to achieve maximum yields to take advantage of high crop prices, it is imperative that crops are kept standing by the use of a robust PGR programme, says Nick Myers, ProCam UK Agronomy Manager. Last year the top 25% of wheat growers in the Procam 4cast agronomy system recorded […]
Affects of Winter now Showing in Crops SAC Overview of Cereal Pests and Disease
This is a busy time of year for cereal growers, with many decisions to make. SAC consultants report winter sown cereal and oilseed rape are reaching the stage where early protective treatments are needed. Meanwhile there is good progress with sowing spring crops on the lighter land, although famers on heavier soils and flatter ground […]
Rudis brassicas approval extended to cauliflower, broccoli and calabrese
The fungicide Rudis with tzt technology has gained approval for use on cauliflower and broccoli/calabrese. Its label now covers all the main outdoor brassica crops. Crops of autumn cauliflower usually require two fungicide sprays to keep them clean through the September to December period of disease pressure. The Allium & Brassica Centres Andy Richardson sees […]
Adding value and maximising profits in 2011
At a recently held briefing hosted by BASF, the message for the industry was clear; high wheat prices mean potentially higher profits from higher yielding crops – but only if correctly managed. Bill Clark, director of Brooms Barn, was quick to point out that this potential opportunity is also one of high risk, if fungicide […]
