Nufarm, PGG and probably others are pushing a new use for Roundup. It goes like this.
- Grow a really nice paddock of lush grass, far too much for your stock to eat immediately, with the aim of fermenting it into silage for feeding out later. But instead of just cutting, chopping & storing as usual, you use this new system
- Spray it with Roundup or equivalent
- Wait for your crop to die
- Cut, chop, store as normal for silage/baleage
- Feed to your animals
Would you knowingly drink milk from cows that eat this food?
Update 11 October 2013
Nufarm have advised by email that
- Every year in NZ over 200,000 ha of pasture is treated with glyphosate and then either grazed by animals within 3-7 days or cut for silage and fed to animals at a later date.
- There is no withholding period. The label recommends not feeding for 3-7 days but you can if you want.
- A number of animal feeding studies have been done around the world regarding this use for glyphosate. None show any safety issues but none have been published. Trust us on this.
- Confidential data was provided to EPA and ACVM (the regulatory bodies in NZ) to get approval for no stock with-holding period.
