Excellent Progression in Oilseed Rape and Winter Cereal Crops

Despite the fact that Oilseed Rape was slower to grow in the first 3-4 weeks this year, another mild autumn across the country has resulted in terrific crop growth as we approach the winter period.

Oilseed Rape will need attention in next few weeks

Very little Phoma presented in crops this year, however as recommended those that needed attention received a fungicide application with growth regulator products including Caramba, Folicur or Prosaro. It is recommended that Oilseed Rape crops are sprayed in the next few weeks for prevention of light leaf spot which is likely to present as an issue due to the weather. Products such as proline (@0.4litres/ha to 0.5litres/ha) is considered the best control for the disease especially on susceptible varieties.

Soil temperatures remain at 10oC at 10cm, however they should soon drop to the required 8o C for propyzamide (i.e. Kerb). If the crop has not received any herbicide as of yet my advice is to apply one as soon as the soil temperature drops close to the required 8oC. This is also an ideal opportunity to apply some boron and a fungicide for the control of light leaf spot.

Still time for more Winter Wheat plantings

Winter cereal crops have also progressed significantly well. At present, it appears that autumn planting of winter cereals are back in the region of 20 to 30% however, with improved weather conditions in the past week, there is still time for more Winter Wheat plantings.

Late September and early October crops have all received a herbicide application. I strongly recommended that any crops that have not had a herbicide applied, should receive an application sooner rather than later; before ground conditions deteriorate. With no IPU available every effort needs to be made as there are no options if grasses are not controlled early.

Growers should now begin assessing crops for Aphids as there may be a great deal of pressure present due to the mild temperatures that presented in October. Early sown crops such as hybrid barleys which have been treated with Redigo are running out of steam and a follow up treatment should be considered if weather conditions are good and if aphids are present. It is generally easier to find aphids once 6 or 7 weeks have passed after the sowing date of the crop.
