With a weighted build-up coating (pellet), our Ultrastrike® pelleted swede seed is designed to be precision drill planted, a method proven to maximise yield through even distribution and consistent growth.

*Based on Cleancrop™ Hawkestone swede crop at $1400/ha yielding 19,000 kgDM/ha. See the case study below for more information.
Seeds treated with Ultrastrike® contain a systemic insecticide and two contact fungicides that provide broad-spectrum protection against key insects (Springtails, Aphids, Argentine Stem Weevil and Nysius) and diseases (Pythium, Fusarium and Rhizoctonia) during plant establishment.
The Cleancrop™ Brassica System eradicates key problem weeds that take away moisture and nutrients from a crop. With the competition down, yield goes up. Combining the power of broad-spectrum herbicide and plants bred to tolerate it, Cleancrop™ maximises crop performance.
*Three main glucosinolates: progoitrin, glucobrassicin and neoglucobrassicin

Crop: Cleancrop™ Hawkestone pelleted swede
Paul and Wendy Stirling operate Wether Hill farm in Ohai, Southland. Traditionally, they use swedes and kale as a source of winter feed, growing 75ha in total. In addition, they often incorporate 5ha of fodder beet into the cropping rotation.
In the past, their swede crops had achieved a 10-12 tonne yield. However, they made the decision to precision drill their swede crops after discussions with their contractor and local retailer representative about trying to increase the yield in the 2017 spring season. They chose the Cleancrop™ Brassica System (Hawkestone pelleted swede) and they increased their yield dramatically. Specifically, they had a 19,000 kgDM/ha crop, established for $1,400/ha, ultimately providing feed for just 7c/kgDM! Paul says, along with the large even bulb size, he is also impressed with how quick the pelleted seed germinates and gets out of the ground compared to traditional seed.
In terms of paddock preparation and crop maintenance, they plough, heavy roll, then apply lime at 2.5 tonne/ha and 300 kgs of superphosphate that is worked in with discs and harrows before precision drilling. More fertiliser is broadcast on afterwards, typically a DAP Boron mix (250 kgs/ha) followed by dressing of urea at canopy closure.
Paul says he gets great payback on the extra investment of precision sowing. The Stirlings have been grazing R1s and hoggets on the Cleancrop™ Hawkestone pelleted swede and have noticed how palatable the stock find it, and their performance has been good too. The Stirlings’ experience proves the potential to lift yields significantly far outweighs any extra cost or effort involved.
