Critical Reasoning (CR) | Re: Inorganic pesticides remain active on the surfaces of fruits

From the replies, I see that the conclusion is :
"But one need not worry about ingesting pesticides when purchasing from farms that use only organic pesticides."

However, from my understanding the conclusion includes both of these statements:
Therefore, when purchasing from a farm that uses inorganic pesticides, one must be careful to wash the produce thoroughly before eating it to prevent the ingestion of toxins.

Could someone help me understand what am I missing here? Thanks.
