Lin has recently become R* spokesperson in the neonicotinoid debate.-The big advantage of neonicotinoids is that you can plant the seed already treated. It means the farmer doesn't have to spray. If you've got to spray, it's very expensive. It's got h*. You have a risk of drift. You have to wait for the right weather conditions, whereas if the plant is protected by the chemistry, coming up it grows. You'll avoid all of those steps.
-From the farmers' point of view, it's really useful.
-It's very useful.
-You are familiar with Professor M*'s work in Germany, where he showed neonicotinoids can have an effect on bees' navigational ability, and that makes being why we've been losing so many bees.
-It might explain it. And I'm not in anyway questioning his data. I think, at certain levels they will have sub* behavioral effects. Whether the amount that bees pick up by for by foraging 1 in crops that are treated neonicos are at the same level to give that effect. I don't know, and I don't think that has been shown.
-Why have some been banned by the EU?
-In my view, the lobbying went along with the fact that the neonicotinoids was suspected was so strong that in the end they got banned on the precautionary principle, on a just in-case principle.
-A lot of people are looking for clearer and simpler answers as to whether neonicotinoids are to blame, but the way that creatures are sensitive as bees intereact with their change against the enviornment is a complex one. For instance, in France, neonicotinoids were banned for a decade, and yet the decline continued, whereas in Australia, the pesticide 2 is still widely used, and the bees remain generally healthy. It just is complex. For me, the most important question here in Britain is about dose, and it affects neonicotinoids having low levels, the sort of levels you will find in the countryside.
