2017 Updates - Winter Linseed
Update July 2017 - Harvest
The harvest of Angora, winter linseed, is completed at local farmer, Tim Sykes's farm. Tim has reported a yield of 3.0mt/ha, which is more than he expected and with new knives fitted and a dry day, Tim's combine driver said "The winter linseed was a lot easier than the oilseed rape". The following video shows just how easy it was to cut and chop the straw....

Current Crop Conditions
Spring management of winter linseed crops is starting to get underway where and when farmers can get onto fields, while the winter has been relevantly dry, the last few weeks have prevented fieldwork from taking place. The vast majority of crops seen to date have well tillered and not to forward, coming in about 10cm in height. Crops this size or smaller can be pushed forward with the first split of N and then canopy size managed with growth regulating fungicides (see winter linseed bulletin 04/17 for full details).
A number of crops have some broad-leaved weed issues to clean up, however as the canopy of the crop is small, there is still time to do this, it is important to get any weed control and growth regulation done before green bud stage in winter linseed.
Crops of 20cm of more height should not receive a first split of Nitrogen, as this will drive excess stem growth and increase the risk of lodging.
There have also been reports of recommendations of Crawler to be applied to winter linseed crops.
No Crawler applications should be made to winter linseed after the New Year, as this will impact on the growth and yield of the crop. Any outstanding Crawler recommendations should now be cancelled.

Current Crop Conditions
The series of cold snaps experienced through November and December have not effected crops, regardless off crop size. Most crops, whether or not they have large amounts of top growth, have put down considerable root systems and this has helped small crops through.
Spring is just around the corner but crops must first pass through the “hungry gap” when pigeons get pushed out of oilseed rape crops and before spring cereals and pluses are planted. At this stage winter linseed is the often the only attractive crop available for pigeons.
That said, the crop is highly tolerant of pigeon grazing and will recover by growing back from the root stock. Often, for every stem grazed off, two new stems will replace it.
The most important thing to watch for pigeon grazing is that it is not uneven, has this will lead to uneven crop growth and impact on management decisions during the spring. Unless crops are very forward, keep pigeons off.
Winter linseed spring management usually starts around the last week of February/ first week of March with first split of Nitrogen and fungicide/PGR timings. Unlike oilseed rape, linseed needs very little nitrogen to get it started post-winter. Also temperatures do not have to get very warm for a linseed crop to go from dormant to full steam ahead, remain vigilant and be prepared to apply a growth regulator fungicide , even on small crops.
Prothioconazole in the form of Proline 275 has been approved for linseed, both winter and spring. Giving growers an extra option for a non-growth regulatory fungicide to partner with actives such as metconazole (Caramba/ Sunorg Pro) that have a growth regulatory ability. This will take pressure off of difenconazole (Plover/Difcor 250EC) which is the most commonly used fungicide partner. Prothioconazole is equal to difenconazole for disease control, especially Pasmo, so crop protection is not being compromised.
