announced that AMVAC Chemical Corp, a wholly owned subsidiary of the Company, will acquire the Phosdrin insecticide business of BASF Agro B.
AMVAC has manufactured and formulated Phosdrin for the international market at its Los Angeles manufacturing facility since 1985 for Shell, American Cyanamid and most recently BASE The acquisition is a necessary step to maintain AMVAC's international sales of Phosdrin.
When AMVAC Chemical Corporation (AMVAC), the registrant of mevinphos, learned that their highly toxic products, Phosdrin
IPA 4 and Phosdrin
4 EC, would be widely used by apple growers in 1993, the company asked WSDA to require additional safety measures.
We note that these record sales were achieved despite the cessation of production of Phosdrin
mid-year; domestic sales of this product accounted for appoximately 14% of the Company's consolidated 1994 sales.
A contributing factor to the decline in gross profit margins in the 1995 period was the reduction of Phosdrin
sales of approximately $2,034,000 for the same period in 1994.
After November 30th, Amvac will recall any Phosdrin
remaining in the marketplace.
Comparable sales were 4% lower in the 1994 third quarter primarily due to a decline in the sale of Phosdrin
, which the Company ceased manufacturing in July 1994.
