Again we will have to disagree on this. May I respectfully suggest that you investigate for yourself facts to justify or otherwise what you assert as your "truth". There is much evidence now emerging that your assumed simple correlation between pesticide use yields is fallacious. This is, as often the case, a complex subject, but to assume maximum pesticide use is the answer to perceived need to improve food production is simplistic in the extreme, and has to be weighed against a host of other considerations including soil fertility, erosion, land use, and of particular concern now water usage and climate change considerations. Certainly, for example, there are recent studies asserting that significant reductions in pesticide use in Europe could be achieved without yield loss, and research published this year by the UN supports the view that the agrochemical industry's dogged promotion of its products is both damaging and unnecessary. I don't intend arguing this further, as it broadens into political and economic issues which are perhaps not all entirely appropriate here, but do urge anyone to do some investigation to avoid buying the chemical industry's hype wholesale.
What I think particularly misleading is the idea that bees are just an incidental but regrettable collateral damage feature of pesticide use. Bees and other insects are vital to pollination of commercial farmed crops. An essential factor in agriculture. At least Gove seems to have realised that.
Back to the issue of most import to ourselves, despite the misleading Telegraph headlines, I have been able to find no evidence of Gove believing in a "total ban" on neonics, (far less on any other bee-harming pesticides, or btw gylphosate, potentially even more damaging to human health). The suggestion is only that the UK would follow or support further EU plans to extend a ban to further crops beyond current restrictions. To my knowledge these do not extend even to commercial glasshouses, far from a "total ban", so maybe the fears raised in the OP are not justified.
