Growers have seized recent spray days and many have managed to complete the scheduled autumn applications although where soils are too wet there are still a few outstanding.
In general, blackgrass pressure this autumn is lower due to a combination of factors including; later drilling dates, more opportunities for stale seedbeds and glyphosate pre drilling with successful pre emergence applications.
Growers still planning to apply autumn Atlantis should be mindful that while December and January applications can work well in milder conditions, the crop should be actively growing. Atlantis applications must be applied at a time that enables the spray to dry on the leaf before the evening dew settles; at this time of year these opportunities are rare. In marginal conditions or where resistance could be an issue good spray techniques are paramount.
In rapeseed, conditions for the completion of propyzamide and carbetamide applicvations are ideal. These actives work best when soils are cool and moist allowing them to be held in the top few centimetres of soil where weeds are germinating.
However, applications should be stewarded to minimise run off into surface water, in particular applications to water logged soil should be avoided. This application also provides an opportunity for a top of phoma control as necessary.
Now is the time to start planning for the spring. Growers should begin calculating their N Max for each crop and planning field-by-field fertiliser applications. And don’t forget to complete your Soil Protection Review by the end of the year.
