I do the entire garden all at once. Doesn't take very long to do, maybe an hour or so. I do change into long pants, no shorts and wear shoes and socks, no sandels. And I wear rubber gloves. But no hasmat suit required. I simply use a hose end sprayer. One of those no premix dial and spray types. Just don't do this on a windy day and be aware of were you are pointing the spray. I don't get any on my skin with this method. And since it does not make tiny air born particles there is nothing dangerous to breath in. Works great. I have been using this method for years.
