Honestly my grandad walked these fields, he farmed here with two farm horses one called Snowball, and he did not use chemicals. The idea struck me just before Christmas that we are the only species on the planet that will actively go out and cover our food with toxic chemicals to stop other living creatures from eating it and then eat it ourselves. That is an amazing forward jump for civilisation, don’t you think?
Using chemicals to ward off disease is as old as organised agriculture, and up until recently bluestone and washing soda, that is Cupper Sulphate and washing soda was used to help prevent blight on potatoes here in Ireland. This is now restricted under organic rules. My Grandad may have used it in the 1950s, and had it been available in the mid-1800s it may have saved millions of people from starvation during the great potato famine, using it would have been the right thing to do.
The key difference today is the scale, the toxicity and the ubiquity of pesticide use. Yes, the EU have been restricting the use of certain pesticides, but it very much looks like their ambition to clean up chemicals in our food will be put on hold for now.
There is also the argument that the dose makes the poison and for something like copper of course if you consume too much of it is toxic, in fact it is more toxic than Glyphosate, this may seem surprising.
But here are two key differences.
1. The use of Glyphosate worldwide is estimated to be 800,000 tonnes annually. For Copper sulphate reliable date does not exist but use is probably around the 10,000-50,000 tonnes mark. (note it is now severely restricted under EU organic standards). Glyphosate is everywhere.
2. Glyphosate is systemic, Cupper is not. Glyphosate gets into the plant and stays there; Copper sits as a barrier on the outside and is easily washed off.
Things are never as black and white as we may want them to be, the famine and the use of copper to protect the potato crop is a good example, if the option was there at the time it would have been the right thing to do to use it.
But today there are clear alternatives to chemical use in vegetable production. For weeding, mechanical and flame weeding are clear chemical free ways to control weeds. Using crops that are more disease resistant is a no brainer, and new varieties are constantly being bred (not GMO, but using natural techniques), take the potato “Connect” which has exceptional blight resistance and tastes great (the earlier Sarpo varieties had great blight resistance, but nobody wanted to eat them!).
For pests, well some crops will succumb that is the nature of nature!
We are often asked how we deal with slugs on our farm, and whilst at times we do use an organic approved slug pellet it is rare and we have virtually no problems. The ecosystem on our farm may be in balance and provides natural protection, as with any balanced system it just works.
So as always without your support we would not be able to continue to fight the good fight, so thank you for standing by us, and Happy New Year.
