 -There are at least pieces of evidence which show really serious impacts from levels of neonicotinoids that bees, wild bees could be exposed to in wild environment.And the arguement against the ban was laid out by one of the pesticide 1 manufacturers.


-These trials show that there is no risk to pollinate or form those ** when used correctly in the environment.
There was a lot of concern in the audience.
-I'm very worried I could still (be) going to buy local supermarket and buy lettuce 2 of garden spray, which contains various neonicotinoids.
It's clearly to me that even though many of the people here tonight had differing opinions, there is a hunger for clarity. 
So I'm heading back to R*, where there is another group of scientists looking at the pesticides 3 from a completely different angle. These dimly-lit red corridors are the first line of the fence against very dangerous collection of insects.
-Why the red light?
-OK. Insects don't really see red light. So, to them, this corridor is dark, which means they are not going to fly out here, which is just a conditional 4 security. Rooms are sealed anyway.
Professor Lin Field wants to show me how we underestimate the value in pesticides.
-This room here.
-So what we've got here?
-OK. So this is actually a Chinese cabbage plant and this is the plant that we verily just introduce the pesticide, and this is the one that's been in the cage with the pester 5 out, maybe a week. And you can see there is very little left. And with the most crops we grow, somewhere between 30 and 40 percent would be lost in pest diseases, if we made no effort to control.
-So in your view, we really need these pesticides?
-In my view at the moment, I think there are some more alternatives, but most of our crop protection does rely on modern chemistry, which are very effective in pesticides, very safe, very low-remaining in toxicity 6, and they play a big role in our food production systems.
