Section XXIII-503 - Chart of Tolerances
Universal Citation: LA Admin Code XXIII-503
Current through Register Vol. 50, No. 9, September 20, 2024
A. Content of active ingredients on all pesticides should be at the level of guarantee. However, determination of compliance based on assay of a single sample shall be made as follows.
1. A single sample whose
assay deviates below the stated guarantee shall be considered in compliance
except as noted in Paragraph 2, below, if its active ingredients are found to
be within the following ranges.
|
Active Ingredient Percent Guaranteed |
Allowable Deviation below Guarantee |
|
Up to 1.00 percent |
15 percent of Guarantee |
|
1.01 percent-19.99 percent |
0.1 plus 5 percent of Guarantee |
|
20.00 percent-49.99 percent |
0.5 plus 3 percent of Guarantee |
|
50.00 percent-100.00 percent |
1.0 plus 2 percent of Guarantee |
2. A
single sample whose assay deviates below the stated guarantee beyond the above
limits may not be considered deficient if special sampling problems such as
those associated with fertilizer-pesticide mixtures and granular formulations
or if problems associated with accuracy, specificity or reproducibility of the
method of analysis can reasonably be expected to have contributed to the lower
assay.
3. A single sample whose
assay ranges above the stated guarantee shall be judged individually. However,
an assay ranging above the stated guarantee shall not be considered violative
if:
a. no illegal residue can be expected to
result when product is used according to label directions;
b. no significant increase in hazard to man
or the environment can be expected to result when product is used according to
label directions;
c. stability of
the formulation or ingredients thereof require over-formulation to insure that
assay over a period stated on the label shall not fall below the minimum
provided in Paragraph 1, above.
