Introduction

Read these notes together with the recommendations given later in this publication. Additional information on use, toxicity and safety precautions is given here. With a few exceptions, the herbicides are listed under their common (generic) rather than their trade or product name. See Table 4-1, Herbicides Used in Ontario to determine the corresponding common name for a particular trade name. For example, Table 4-1 indicates that the trade name AATREX has a common name of atrazine; notes on AATREX are listed under atrazine in this section. See Chapter 5, Notes on Adjuvants, for information on adjuvants.

Complete information on each herbicide is available on the product label which is located on the herbicide container. The federal Pest Management Regulatory Agency also lists pesticide labels on their internet website. Many herbicide manufacturers also list product labels and/or Material Safety Data Sheets (MSDS) on their websites.
