Well, it IS a protein, and being organic it's not too surprising. Rooting
hormones similarly degrade, especially when warm or in sunlight, as does
azadirachtin in neem oil.

Each bag of Messenger® for Home and Garden contains 8 ounces of material,
sufficient to make up to 100 gallons of finished spray solution, enough to
treat approximately 1 to 2 acres of landscape. This package is only
appropriate for large scale applications, and must be used within three
weeks after opening.
Messenger is effective at low use rates and degrades rapidly in the
environment, leaving no detectable residue on plants or in the soil. Once
a
plant is treated, activation is generally initiated within 5 to 10 minutes
and full response occurs within 3 to 5 days. Resulting effects typically
continue for 2 to 3 weeks, depending on the type of plant.



Interesting that the product only has a shelflife of 3 weeks after
opening!
