Stress tolerance is as important as output in modern oilseed rape varieties if growers are to cope with today’s economic and environmental challenges, according to leading European specialist breeder, Laurent Verdier.
Bayer is increasing the quantities of its potato herbicide Artist (flufenacet + metribuzin) this season in response to greater demand arising from frustration at the lack of effective options for tackling harder-to-control weeds, such as annual meadow grass (AMG) and cleavers.
CEREAL crops checked by the cold spring, are expected to leap forward with warmer weather and rising soil temperatures, and some experts are advocating a strong PGR programme now to give high yielding plants the strength to stand until harvest.
Verticillium wilt could hit oilseed rape crops hard this season, with crops already under stress from unprecedented cabbage stem flea beetle larvae attack and the effects of the prolonged waterlogging last autumn which reduced rooting.
THE occasional warm days have triggered flights of pollen beetle into winter oilseed rape and this is coinciding with the crop being at its most vulnerable, green-yellow bud stage, Dr Andy Evans, of SRUC Crop and Soil Systems, has warned.
Suspicions that the aggressive ‘Warrior 3’ rust race could be a threat this season have been raised by crop breeders, Limagrain UK, which is asking growers to be extra vigilant when checking wheat crops.
