Many white clover seed crops are approaching desiccation. The article below outlines a range of options for growers to consider.
Key points
- Options for desiccation of white clover seed crops depend on the importance of re-growth for lamb grazing.
- Previous years’ data from Lincoln suggested there was no difference in seed yield between the chemical desiccation treatments.
- All desiccation treatments yielded higher than the windrow treatment.
- GreenMan™ offers an alternative to Reglone® but it is expensive and may need to be followed with a second application if the crop is bulky or harvest is delayed due to poor conditions.
- Glufosinate (Buster®) is an alternative to MCPA as a pre-desiccant that reduces the risk of the canopy collapsing prematurely (which reduces diquat efficacy).
