  2. Effect of lauricidin and ethylenediaminetetraacetic acid on growth of nine hymenomycetous fungi.

    Growth of nine wood-decaying basidiomycetes was measured on media containing 10, 100, and 1,000 parts per million (p/m) Lauricidin with or without 0.1 percent ethylenediaminetetraacetic acid (EDTA). EDTA alone significantly reduced the growth of all fungi tested. Lauricidin at 1,000 p/m significantly retarded the growth of all fungi except two: Ganoderma...

Nineteen individual pest risk assessments were prepared, eleven dealing with insects and eight with...
