Where can I find information regarding chemicals approved in the U.S. but not in Canada or approved in Canada but not in the U.S.?
One good place is the International Pesticide & Application Database (IPAD) online at: www.globalmrl.com/db#query
IPAD helps users determine rates and limitations on the usage of agricultural pesticides. IPAD is a crop specific database that cross references pesticides by chemical brand name, method of application, rates and frequency of application, as well as pre- and post-harvest interval. The database contains information for the U.S., Mexico, and Canada, 42 crops, 1400 active ingredients, 29 pesticide types, and 14 different timings resulting in nearly 24 million combinations. The IPAD system provides chemical use practices in order to ensure compliance with a target country’s MRL standards and provides practical guidance to maximize the benefit to the U.S. producer.
