Fight to the finish

On my way home from work today, I saw a tractor, arms spread spraying his crop in the Warwickshire countryside. Just happened to catch the farmer near his field gate. I asked him what job he was on. "Insects he said, protecting before the invasion". I dont know what he was spraying and I dare not ask but I would be of the same frame of mind as I want food on my table and not in the pea moth belly. I dont want to upset organic gardeners but This year I will fight to the finish to keep a healthy crop. Looks like being a warm summer so.....weapons at the ready sir! Men are dirty, guns are clean!

My survival isn't dependent upon the produce from my garden. Until that day comes, I'll stay away from pesticides. Actually even if that were the case, I still wouldn't use them. 
Have you looked into integrated pest management?

personally i think for the small scale of the allotment organic is actually cheaper. you also don't have to have a science degree to mix all the chemicals that they do on the farms.

what pests do you have problems with?
