Methods are developed to extract and quantitate the avicide 3-chloro-p-toluidine hydrochloride (CPT HCl) from rough-hulled rice and ethyl-cellulose-coated rice baits using high-performance liquid chromatography. The mobile phase used in the ethyl-cellulose-coated rice matrix method is an acetonitrile(ACN)-phosphate buffer (60:40) at

Gross and microscopic changes in response to single po. doses of avicide 3-chloro-4-methyl benzamine HCl were studied in rooks (Corvus frugilegus L.) and pheasants (Phasianus colchicus L.). The observed changes followed a dose- and survival time related pattern and rooks

A probabilistic model was developed to estimate target and non-target avian mortality associated with the application of the avicide CPTH (3-chloro-p-toluidine hydrochloride) to minimize sprouting rice damage in the southern USA. CPTH exposures for individual birds were predicted by random
Randal S Stahl et al.
Journal of agricultural and food chemistry, 50(4), 732-738 (2002-02-07)
A method using a deuterated surrogate of the avicide 3-chloro-p-toluidine hydrochloride (CPTH) was developed to quantify the CPTH residues in the gastrointestinal (GI) tract and breast muscle tissues in birds collected in CPTH-baited sunflower and rice fields. This method increased
