Regulatory Directive: Classification of Beans on Labels and Research Requirements
28 October 1993
Cat. No.: N/A
The purpose of this document is to inform pesticide registrants and other interested groups and agencies about the terminology used to designate bean crops on pesticide labels.
This Regulatory Directive replaces Trade Memorandum T-1-217 dated February 14, 1980.
The terminology used to designate bean crops, on pesticide labels and in various indices and information systems published by the Plant Industry Directorate requires clarification. Registrants frequently enquire if data produced on one species or variety of bean can support registration for use on other species or varieties of beans. Extension specialists and growers often find it difficult to interpret from a label the exact bean crop(s) for which a pesticide is intended. To resolve these difficulties, a standard policy has been established to regulate the names of bean crops used on labels.
The following terminology should be used on labels to describe bean crops. The exact meaning of each term is explained after the name.
A degree of extrapolation is generally possible among divisions; all applications, however, will be evaluated individually.
Phytotoxicity data will be required for each division of beans and for a number of bean types within Divisions VII and VIII. This is especially true for herbicides.
If data are presented on a number of types of beans within a division, extrapolations may be made to include the whole division. Otherwise, the label claims will be limited to the bean types on which use tests have actually been conducted.
When evaluating applications for registration of pesticides for use on beans, pre-harvest intervals and corresponding residue data are required. Maximum residue limits vary depending on end use and, accordingly, the following uses for beans are considered:
- human consumption
- pods and/or seeds in succulent form;
- dried seeds; and
- processed seeds (e.g., soybean oil).
- livestock consumption
- bean meal from seeds (i.e., fababeans, soybeans);
- immature plants for silage (i.e., fababeans, soybeans - after the pods develop, but before they mature); and
- crop residues (vines, hulls) for feed after harvest (i.e. snap common beans).
If any of the above situations are not covered by residue data submitted in support of the application, suitable limitations must appear on the label.
Residue data are required for all bean divisions. For common beans (snap and dry) residue data is usually required for several types from each group. For further information on residue data requirements and latitudes which may be taken in extrapolating among divisions, consult with officers in the Chemical Evaluation Division, Foods Directorate, Health Canada, Ottawa, Ontario, K1A 0L2.
