Pesticides play an important role in growing crops such as this barley |
Farmers
nowadays have to deal with a much reduced availability of pesticides than they
were once used to. Since the introduction of EU regulation 91/414 in 1993 the
number of active ingredients has fallen from over 900 to around 300. A further fall
to around 150 actives (as they are known) by 2020 should be anticipated, which
means a reduction of around 85% in all actives over a 20 year period.
This
is further compounded by the slowing down of the development of future actives,
as agro-chemical companies have a reduced the pool of money needed to produce
new chemistry and also baulk at the huge costs of “re-registering” older
products to conform to new legislation, especially if the product is for a
niche market and thus not widely used.
I
expect many of you will view this as great news – less of those beastly
pesticides that we know are so incredibly damaging to our environment, because
we have read all about them in the newspapers – so it must be true.
But
maybe, just maybe, that is a rather complacent attitude as we sit in our
comfortable houses, having just eaten a large meal, discussing what we might take
out of our packed freezer to defrost for the next meal. It is so easy to criticise on a full tummy.
Yes, of course we all want to produce our food
more sustainably – that is, I hope, obvious to us all. However, pesticides play
a hugely important role in providing enough food to put on our plates. Without
them we would need much more land to turn over to arable crops, simply to grow
what we do presently. Is that the sustainability we are looking for?
Meanwhile, the hoops through which a new chemical has
to jump well before it gets anywhere near to being sprayed onto a
field are extraordinary, and rightly so. If for instance
you had just discovered salt and decided that it potentially could be turned
into a useful pesticide, it might surprise you that it would get kicked into
touch long before it got anywhere near to a field trial.
The
decline of available pesticides, especially if new chemistry is not forthcoming,
will undoubtedly see a growing reliance on just one or two products, risking the
likelihood of resistance building up amongst insect pests, fungus and weeds. If
that does happen, we could see massive declines in crop productivity across the
world, at a time when we need to be producing more food to feed an ever increasing
population.
If the
above scenario plays out in reality, it would of course rapidly increase food prices, affect
the availability of certain produce and result in a big rise in the already
unacceptable human starvation figures.
A little food
for thought.
