the problem is copper deficiancy, after doing leaf analysis, my copper levels
were in the bottom of the scale, alsso in soil analysis, added Kocide 3000 to

Hi!
I’m not sure I understand:

Strep is extremely stable if it is kept dry and out of direct light (e.g., in a
closed cardboard drum or foil package). It does break down in sunlight. I
don’t know if other components in the formulations might “age out” and become
less effective (e.g., less surfactant activity), but the strep

Do you have a good reference for me on this specific topic? When I reviewed the
