Fonterra has detected traces of the nitrification inhibitor dicyandiomide (DCD) in cows milk. The following is pertinent:
Two extracts below from the "facts box" in Alan William's article in the latest NZ Farmers Weekly:
DCD was developed about 30 years ago and is a non-toxic, water-soluble compound that breaks down rapidly in the soil and leaves no lingering residue. What research did Alan refer to when verifying this statement? If this statement is true then are the DCD residues that have been detected in milk a consequence of:
The product not being used according to the product label directions for use?
The fact that the product label information does not warn the user that inproper use may lead to product residues contaminating milk (and meat)?
"Treated" pastures being grazed too soon after product application?
The fact that the product label information does not include a pasture withholding period to allow DCD pasture residue to be washed off the plant and absorbed into the environment?
New Zealand is the only country spraying DCD on to pastures though it has a range of uses in other countries. If this is true then there will be no overseas research on the behaviour of DCD sprayed directly onto pasture in terms of:
its residual capability on the pasture.
Whether it is uptaken by plants through plant roots into the leaves
Its accumulation in the pasture consumers blood or milk.
What research into the above was required of Ballance Agri-Nutrients and Ravensdown by the regulatory authorities before they were given approval to release the product for general use and what research was actually done and published by these two companies?
