I. 
The labeling referred to above, submitted in connection with 
registration under the Federal Insecticide, Fungicide, and 
Rodenticide Act, as amended, is acceptable, subject to the comments 
listed below. 
1. Throughout the use directions, the symbol ";",, is missing, 
replaced on the label copies with a slanted plus sign. 
We believe this is a word processing error, rather than 
a change to the directions for use, therefore, in order 
to accept this labeling, we have manually corrected the 
errors. This must be corrected on your final printed 
labels. 
2. In the "Agr icul tural Use Requirements," page 8, the 
symbol for the distance of "%" is also missing due to a 
word processing error. We have also manually corrected 
this error. Please ensure that this is corrected on your 
final printed labeling. 
3 . In the last sentence on page 9, the word "quipped" should 
be "equipped." 
4. In the directions for use on sorghum, change the word 
"completed" to "completely." 
5. The instructions for storage of this product should read 
" ... may exceed 120°F or below 45°F." Please ensure that 
the final printed labeling includes the degree sign, 
rather than an "x".
