FORM 10-K FOR THE YEAR ENDED JULY 31, 2004

Comment applicable to your overall filing

1. Where a comment below requests additional disclosures or other
revisions to be made, please show us in your supplemental response
what the revisions will look like.  These revisions should be
included in your future filings.

Management`s Discussion and Analysis

2. We note that you summarize quarterly financial information in
Note
14.  Please discuss any seasonal aspects of your business which
have
had a material effect on your financial condition or results of
operation.  See instruction 5 to Item 303(b) of Regulation S-K and
paragraph 30(c) of APB 28.


Results of Operations, page 14

3. Please disclose the extent to which acquisitions, changes in
prices, amounts of shipments, or the introduction of new products
contributed to fluctuations in revenues.  Refer to Item
303(a)(3)(iii) of Regulation S-K.

4. Please quantify the impact of each factor when multiple factors
contribute to material fluctuations.  For example, selling,
general
and administrative expenses increased in fiscal 2004 due to the
acquisition of the Wood Protection Products distribution business,
increased amortization of the cost of your animal health and penta
acquisitions, and compensation of new personnel to support those
acquisitions; please quantify each of these factors.  Refer to
Item
303(a)(3)(i) of Regulation S-K and Financial Reporting
Codification
501.04.

5. Your discussion of gross profit on page 15 indicates that you
starting reselling penta blocks in December 2003 after signing a
long
term supply agreement.  Please disclose how you report these
revenues
and corresponding costs of sales given the provisions of EITF 99-
19.


Liquidity and Capital Resources

Contractual Obligations, page 19

6. Please revise your table of contractual obligations to include
the
following:

* Estimated interest payments on your debt;
* Estimated payments under interest rate swap agreements; and
* Planned funding of pension and other postretirement benefit
obligations.

Because the table is aimed at increasing transparency of cash
flow,
we believe these payments should be included in the table.  Please
also disclose any assumptions you made to derive these amounts.


Financial Statements

7. Please display comprehensive income and its components in a
financial statement, which should have the same prominence as
other
financial statements.  Refer to paragraph 22 of SFAS 130.


Note 1.  Summary of Significant Accounting Policies, page 29

8. Please disclose the types of expenses that you include in the
cost
of sales line item and the types of expenses that you include in
the
selling, general and administrative expenses line item.  Please
tell
us whether you include inbound freight charges, purchasing and
receiving costs, inspection costs, warehousing costs, internal
transfer costs, and the other costs of your distribution network
in
the cost of sales line item.  With the exception of warehousing
costs, if you currently exclude a portion of these costs from cost
of
sales, please disclose:
* in a footnote the line items that these excluded costs are
included
in and the amounts included in each line item for each period
presented, and
* in MD&A that your gross margins may not be comparable to those
of
other entities, since some entities include all of the costs
related
to their distribution network in cost of sales and others like you
exclude a portion of them from gross margin, including them
instead
in a line item, such as selling, general and administrative
expenses.


Foreign Currency Translation, page 30

9. Given the guidance provided in paragraphs 5 through 8 of SFAS
52,
tell us how you determined it is appropriate to use the U.S.
dollar
as the functional currency for each of your foreign operations.
Also, please tell us how your accounting of KMEX, which is
discussed
in Note 5, complies with SFAS 52.


Segment Reporting, page 31

10. Given the manner you present yourself in Item 1 (Business) in
which you discuss entering into three different types of
businesses
(wood preserving chemicals, animal health pesticides, and
agricultural chemicals) through acquisitions, it appears that you
may
have aggregated certain operating segments in arriving at your
reportable segment.  If you have aggregated operating segments,
please explain to us how these operating segments met the
aggregation
criteria of paragraph 17 of SFAS 131.  Please help us understand
how
you determined you have one reportable segment under SFAS 131.


Note 2.  Acquisitions, page 32

11. Given the purchase price of the Wood Protection Products
acquisition was $7.2 million, which represents approximately 22%
of
your total assets at July 31, 2003, please help us understand how
you
determined you did not need to provide any financial statements of
businesses acquired pursuant to Rule 3-05 of Regulation S-X.

12. In June 2004, you purchased creosote product registrations as
well as the Ravap tradename and inventory.  Tell us how you
accounted
for these transactions.  Your explanation should refer to the
accounting guidance used to determine the appropriate accounting.


Note 7.  Intangible and Other Assets, page 36

13. For each of the intangible assets not subject to amortization,
please address the following:
* Tell us how you determined they have an indefinite life;
* Tell us what life was being used for amortization purposes prior
to
the adoption of SFAS 142; and
* Disclose how you assess your indefinite-lived assets for
impairment
in accordance with paragraph 17 of SFAS 142 and EITF 02-7.


Note 13.  Stockholders` Equity, page 40

14. You state that the numerators and denominators of basic and
diluted earnings per share computations take into account vested
stock options whose strike price is less than the market price in
accordance with SFAS No. 128.  We remind you that paragraph 17 of
SFAS 128 states that equivalents of options and warrants, which
should be included in the calculation of diluted earnings per
share
amounts, include nonvested stock granted to employees, stock
purchase
contracts, and partially paid stock subscriptions.  Please tell us
how your calculation of diluted earnings per share complies with
paragraphs 11 through 35 of SFAS 128.  Please also confirm that
all
warrants and options, including those issued to nonemployees, were
included in your calculation of diluted earnings per share.  For
example, we would expect the options issued as part of the
consideration for the Wood Protection Products acquisition to be
included in your calculation of diluted earnings per share.



Note  14. Selected Quarterly Financial Data, page 44

15. Please disclose in a footnote to the quarterly financial data
the
nature of any adjustments that are material to the results of a
particular quarter.  In this regard, we note that you incurred an
operating loss in the second quarter of fiscal 2004.  See Item
302(a)(3) of Regulation S-K.

Schedule II - Valuation and Qualifying Accounts, page 48

16. Please describe the column entitled "Deductions" in a footnote
to
the schedule or in the column heading as appropriate.  See Rule
