CUSIP No. 030371108                                 SCHEDULE 13D

--------------------------------------------------------------------------------

                                SECOND AMENDMENT

Item 1. Security and Issuer.

        This Amendment No. 2 relates to the common stock, $.10 par value per
share (the "Common Stock"), of American Vanguard Corporation, a Delaware
corporation (the "Company"), whose principal executive offices are located at
4100 East Washington Boulevard, Los Angeles, California 91504. An original
Schedule 13D was filed by Glenn A. Wintemute and Herbert A. Kraft on November 4,
1983 (the "1983 Filing"). An Amendment No. 1 to the 1983 Filing was filed
November 19, 1984 (the "1984 Filing").

Item 2. Identity and Background.

        Two persons are jointly filing this statement: Herbert A. Kraft and
Glenn A. Wintemute (sometimes referred to herein as the "Reporting Persons").
Reference is made to the discussion set forth under Item 2 of the 1983 filing,
which information is incorporated herein by this reference.

Item 3. Source and Amount of Funds or Other Consideration.

        Certain information with respect to the shares previously owned by the
Reporting Persons, is set forth in Item 3 of the 1983 filing and Item 3 of the
1984 filing, which information is incorporated herein by this reference.

        On May 10, 1985 the Reporting Persons acquired 55,449 shares of the
Common Stock of the Company. These shares were acquired pursuant to a three-year
promissory notes delivered to each selling stockholder providing for semi-annual
payments of interest; such payments are secured by a pledge of the shares of
Common Stock so acquired. No down payment was required by the Stock Purchase
Agreements, and no decision has been made by the Reporting Persons as to the
method of obtaining funds necessary to make the installment payments called for
under the promissory note.

        The above-referenced purchase is evidenced by a Stock Purchase Agreement
identical in form to that attached as Exhibit 1 to the 1983 filing. That Exhibit
1 to the 1983 filing is hereby incorporated herein by this reference.

Item 4. Purpose of Transaction.

        At the time of the acquisition of shares of the Common Stock by the
Reporting Persons described in the 1983 filing, the 1984 filing, and in the

        The Reporting Persons are both directors and executive officers of the
Company.

        The Reporting Persons do not intend to materially change the Company's
