were lower than the first quarter of the prior year.

growth.

Agricultural Chemicals: Total sales in the segment were slightly lower than in the first quarter ofFY 2003. While sales of household insecticide increased, sales of plant protection chemicals declined
because of the stronger yen. In addition, feed additive sales were lower than in the first quarter ofthe previous year, due to continued low prices in overseas markets.
