- Kline (Anonymous, 1982)
- Kline (Anonymous, 1982) and U.S. EPA Pesticide
Product Label System. The major active ingredients associated with "other" manufacturers
are unknown. However, we believe that the "other" manufacturers
used the same active ingredients, in the same proportions, as the knowns.
- Based
on judgment.
- Eliminating duplicates.
- Combining active ingredient
percent sales across all products in which it appears.
- We divided
the percent sales of each active ingredient by 66% because the total
for the known active ingredients is 66%; this effectively apportions
the "other" active
ingredients into each of the known active ingredients (under the assumption
that the "others" are similar to the known).
