Title Preliminary Dose Range Study with Carbendazim

No
New health or environmental hazard
The TM/MBC Task Force-MBC Technical Committee (by way of the Canadian registrant for thiophanate-methyl) is submitting preliminary information on adverse effects determined from a Preliminary Dose Range Study with Carbendazim. Specifically, considering this study was conducted using the dietary means of exposure, effects were seen on the number of pups delivered and on pup growth at the highest dose tested (10,000 ppm). In short, groups of five time-mated female Wistar rats were exposed to four treatment levels of 0, 2500, 5000, and 10000 ppm via diet during gestation, lactation and post-weaning through PND 28. Based upon maternal toxicity, reduced number of females pregnant and pup toxicity (decreased body weight and decreased survival) found at the highest dose (10000 ppm) it is evident this dietary concentration exhibited an effect on the dams and offspring via the dietary route of exposure. The results of this preliminary study will be used to determine doses for a more definitive range-finding/pk study which will be used in the preparation of the definitive modified one-generation study slated to begin in 2010.

Previous tests of this nature were conducted using gavage administration of the test item. This study administered the test item through the diet. As a result, the findings were reportable under 6-A2 to the United States Environmental Protection Agency. The registrant respectfully reports the same findings to the Canadian Pest Management Regulatory Agency. No final report of the study is available at this time.
