The knowledgeable Italophile has suggested the use of DiPel in controlling tomato caterpillars. However, search as I might, the only suppliers I can find are in The USA. The problems are twofold. a) It is only sold in large quantities b) American suppliers will not ship to the UK (I suspect transportation costs would be prohibitive if they did)
Can anyone suggest a UK supplier for a domestic gardener, or even an alternative trade name which is available.
I suspect any advice will be keenly followed by a lot of viewers.
