O,O-diethyl phosphorothioate O-ester with phenylglyoxylonitrile oxime (Bay 77488) as a Mothproofer of Woolen Fabrics

O,O-diethyl phosphorothioate O-ester with phenylglyoxylonitrile oxime (Bay 77488) at calculated deposits as low as 0.05% by weight satisfactorily protected woolen cloth against feeding damage by. larvae of the black carpet beetle Attagenus piceus (Olivier) and of the webbing clothes moth Tineola bisselliella (Hummel). The biological data also showed the Bay 77488 residues to be moderately resistant to washing. highly resistant to drycleaning, and persistent through aging for at least 12 months. The oral LD 50 to rats is more than 1000 mg/kg.

Moth Resistance of Glutaraldehyde-Stabilized Wool

In any case, examination of the deviations observed (Fig. 3 in reference [1]) lead to maximum differences of the order of i0.07 in. (1.8 mm), which seems to be excessive from the point of view of industrial practice, which confirms the conclusions from a study of the present authors [3] where a warning is expressed on the dangers of estimating the parameters of the array from data of the Digital Fibrograph. It is evident that the technique proposed by Louis and Fiori is interesting, but its practical application seems to be subject to certain limitations; above’ all if there
