Bifenthrin TC, EC, WP

BIFENTHRIN TECHNICAL MATERIAL

FAO Specification 415/TC (March 2024*)

This specification, which is PART ONE of this publication, is based on an evaluation of data submitted by the manufacturers whose names are listed in the evaluation reports (415/2009, 415/2010, 415/2014, 415/2016, 415/2021 & 415/2023). It should be applicable to TC produced by these manufacturers but it is not an endorsement of those products, nor a guarantee that they comply with the specification. The specification may not be appropriate for TC produced by other manufacturers. The evaluation reports (415/2009, 415/2010, 415/2014, 415/2016, 415/2021, & 415/2023), as PART TWO, form an integral part of this publication.

1 Description

The material shall consist of bifenthrin, together with related manufacturing impurities, in the form of a light brown to amber viscous liquid, crystalline solid, or waxy solid with a faint, slightly sweet odour free from visible extraneous matter and added modifying agents.

2 Active Ingredient

2.1 Identity test (AOAC INTERNATIONAL: Bifenthrin Analysis in Technical Material and Formulations by Capillary Gas Chromatography, Note 1)

The active ingredient shall comply with an identity test and, where the identity remains in doubt, shall comply with at least one additional test.

2.2 Bifenthrin content (AOAC INTERNATIONAL: Bifenthrin Analysis in Technical Material and Formulations by Capillary Gas Chromatography, Note 1)

The bifenthrin content shall be declared (not less than 930 g/kg) and, when determined, the mean measured content shall not be lower than the declared minimum content.

BIFENTHRIN WETTABLE POWDER

FAO Specification 415/WP (February 2022*)

This specification, which is PART ONE of this publication, is based on an evaluation of data submitted by the manufacturer whose names is listed in the evaluation reports (415/2009 and 415/2010). It should be applicable to relevant products produced by this manufacturer but it is not an endorsement of those products, nor a guarantee that they comply with the specification. The specification may not be appropriate for the products of other manufacturers. The evaluation reports (415/2009 and 415/2010), as PART TWO, form an integral part of this publication.

1 Description

The material shall consist of a homogeneous mixture of technical bifenthrin, complying with the requirements of FAO specification 415/TC (March 2024), in the form of an off-white to tan powder, together with fillers and any other necessary formulants. It shall be in the form of a fine powder free from visible extraneous matter and hard lumps.

2 Active ingredient

2.1 Identity tests (AOAC INTERNATIONAL: Bifenthrin Analysis in Technical Material and Formulations by Capillary Gas Chromatography, Note 1)

The active ingredient shall comply with an identity test and, where the identity remains in doubt, shall comply with at least one additional test.

2.2 Bifenthrin content (AOAC INTERNATIONAL: Bifenthrin Analysis in Technical Material and Formulations by Capillary Gas Chromatography, Note 1)

The bifenthrin content shall be declared (100 g/kg) and, when determined, the average content measured shall not differ from that declared by more than 10% of the declared content.

3 Relevant impurities

Water (MT 30.6, CIPAC Handbook P, p. 222, 2021)

Maximum: 30.0 g/kg

4 Physical properties

4.1 Wet sieve test (MT 185, CIPAC Handbook K, p. 149, 2003)

Maximum: 2 % retained on a 75 μm test sieve.

4.2 Suspensibility (MT 184.1, CIPAC Handbook P, p. 245, 2021) (Notes 2, 3 & 4)

Minimum 60% after 30 minutes in CIPAC Standard Water D at 25 ± 5°C

4.3 Persistent foam (MT 47.3, CIPAC Handbook O, p.177, 2017) (Note 5)

Maximum 15 ml after 1 min.

4.4 Wettability (MT 53.3.1, CIPAC Handbook F, p.165, 1995)

The formulation shall be completely wetted in 3 min without swirling

5 Storage stability

5.1 Stability at elevated temperature (MT46.4, CIPAC Handbook P, p.232, 2021)

After storage at 54 ± 2°C for 14 days, the determined average active ingredient content must not be lower than 95% relative to the determined average content found before storage (Note 6) and the formulation shall continue to comply with the clause for:

–wet sieve test (4.1),

–suspensibility (4.2)

–wettability (4.4).
