Your last point speaks to Bond's intent, which makes this an interesting narrative, but she was not charged with attempted murder.

Bond was charged with possessing, transporting, and spreading the chemicals, which have been classified as toxic (along with vinegar and chocolate). This is because the state police and prosecutor exercised prosecutorial discretion by not charging Bond, and the federal government has no jurisdiction over one person "trying to poison another".

edit: though intent is unimportant, it has been alleged that Mrs. Bond caused a rash on the victim, which is relevant, because this would be evidence of "harmful effects on plants or animals".
