for registration upon request.
c) Warning or caution statements are required on the label for
any product which contains 0.03% or more of boron in a water-soluble form or
0.001% or more of molybdenum.
d) Any of the elements listed in 8 Ill. Adm. Code 210.60(a) which
are guaranteed shall appear in the order listed, immediately following the
guaranteed analysis for the primary nutrients, nitrogen, phosphorus and
potassium.
e) An element is considered "available" if the form in
which it is added to the product has been shown to give plant responses or if
the element can be dissolved from the product in water or in some other solvent
which is recognized to indicate availability to plants.
f) When 0.001% or more of molybdenum is added to an agricultural
fertilizer, the purchaser is to receive a caution statement as follows:
"CAUTION: This fertilizer is to be used only on soils
which respond to molybdenum. Crops high in molybdenum are toxic to
ruminants."
