Exhibit 99.1

PLANET POLYMER TECHNOLOGIES HAS SMALL FIRST EVER PROFIT

      San Diego, CA-May 13, 2003-Planet Polymer Technologies, Inc. (OTC BB:
POLY.OB) a San Diego advanced materials company, reported revenues for the
quarter ending March 31, 2003 of $156,620 and a net profit of $722 compared to
revenues of $35,531 and loss of $155,041 for the same period in 2002. The small
profit resulted in (.00) per share compared to a loss of (.02) in 2002. .

      Planet and Agway Inc., entered into two separate Sales and Licensing
Agreements that redefine previous agreements relating to the agricultural feed
and fruit and vegetable coating technologies developed by Planet. Agway's
up-front payment of $130,000 was the primary reason for Planet's small, first
ever quarterly profit. Agway also agreed to return all of its 3,000,000 shares
in Planet common stock, which represents approximately one-third of the issued
and outstanding shares of Planet.

      Ryer Industries defaulted on its obligations to Planet to pay the
remaining balance of the purchase price for Planet's metal injection molding
technology and assets. Planet repossessed those assets in April and resold them
in May to Ryer Enterprises, LLC, a newly formed entity which intends to continue
the commercialization of the AQUAMIM products. The sales price is $301,000 with
a down payment of $25,000 and twenty-four monthly payments of $11,500 commencing
June 1, 2003. Ryer will also pay a monthly royalty for 8 years. .

      The focus of the Company's limited activities will be to help Agway or
their successor(s) fully commercialize their agrotechnology businesses and to
help Ryer Enterprises successfully penetrate the metal injection molding market.
There will be little, if any, marketing or new development work as the Company
strives to maximize its net royalty income from existing product technologies.
