>Also, the dose makes the poison, and don't we try to wash off most of what we spray on crops?

You absolutely SHOULD wash everything before you put it in your body, but there are a lot of chemicals that plants can/do absorb that can't be washed off.

Example: RoundUp

RoundUp sprayed onto a field will cause the plants to dry out. Intended purpose: Spray this on the weeds to kill them. Unintended usage: Is your wheat/corn/soybeans still wet because it's raining during harvest? Douse the field in Roundup, and the crop will dry out while still covered in water.

You end up ingesting it, because it's INSIDE the corn/wheat/soybeans. BUT it doesn't end there, think about the thousands of products that the corn/soybeans/wheat gets processed into.

You can't wash a loaf of bread.
