Serenade - EB

[Boo]

Has anyone used Serenade for fungal control for tomato plants?
I sprayed my tomato plants with Saranade last evening for EB -
Here's information from their website
"SERENADE Garden provides protection against a broad spectrum of the
most common fungal and bacterial garden diseases, yet is completely
non-toxic to bees and beneficial insects. It is so safe you can
confidently harvest and eat fruits and vegetables the very same day
they are treated. Unlike sulfur-based disease control products,
SERENADE Garden is non-irritating to skin and lungs. And, unlike neem
oil-based products that can injure plant foliage, there is no weather
or timing restrictions limiting its application."
<http://www.serenadegarden.com/> but the instructions on the
container label read
PERSONAL PROTECTIVE EQUIPMENT (PPE)
Applicators and other handlers must wear:
• Long-sleeved shirt and long pants
• Waterproof gloves
• Shoes plus socks

As a general precaution, when exposed to high concentrations of a
living microbial product such as this, wear a dust particle mask
when mixing or applying this product. Repeated exposure to
high concentrations of microbial proteins can cause allergic
sensitization.

Follow manufacturer’s instructions for cleaning and maintaining PPE.
If no instructions are available, use detergent and hot water for
washables. Keep and wash PPE separately from other laundry.

So I went out and sprayed looking like I was messing with something as
dangerous as Agent Orange - very uncomfortable with all those clothes
on and a dust particle mask!
Since it's so safe to use, why all the precautions? I would love opinions on your use of Serenade.
Thanks
