Flusilazole TC, EC, EW

FLUSILAZOLE TECHNICAL MATERIAL

FAO specification 435/TC (April 2008∗)

This specification, which is PART ONE of this publication, is based on an evaluation of data submitted by the manufacturer whose name is listed in the evaluation reports (435/2007). It should be applicable to TC produced by this manufacturer but it is not an endorsement of those products, nor a guarantee that they comply with the specifications. The specification may not be appropriate for TC produced by other manufacturers. The evaluation report (435/2007), as PART TWO, forms an integral part of this publication.

1 Description

The material shall consist of flusilazole together with related manufacturing impurities, in the form of odourless white crystals, and shall be free from visi-ble extraneous matter and added modifying agents.

2 Active ingredient

2.1 Identity tests (435/TC/(M)/2, CIPAC Handbook H, p.172, 1998)

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 Flusilazole content (435/TC/(M)/3, CIPAC Handbook H, p.172, 1998)

The flusilazole content shall be declared (not less than 925 g/kg) and, when de-termined, the average measured content shall not be lower than the declared minimum content.

FLUSILAZOLE EMULSIFIABLE CONCENTRATE

FAO specification 435/EC (April 2008∗)

This specification, which is PART ONE of this publication, is based on an evaluation of data submitted by the manufacturer whose name is listed in the evaluation report (435/2007). It should be applicable to relevant products of this manufacturer, and those of any other formulators who use only TC from the evaluated source. The specification 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 who use TC from other sources. The evaluation report (435/2007), as PART TWO, forms an integral part of this publication.

1 Description

The material shall consist of technical flusilazole, complying with the requirements of FAO specification 435/TC (April 2008), dissolved in suitable solvents, together with any other necessary formulants. It shall be in the form of a stable homogeneous liquid, free from visible suspended matter and sediment, to be applied as an emulsion after dilution in water.

2 Active ingredient

2.1 Identity tests (435/EC/(M)/2, CIPAC Handbook H, p. 176, 1998)

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 Flusilazole content (435/EC/(M)/3, CIPAC Handbook H, p. 176, 1998)

The flusilazole content shall be declared (g/kg or g/l at 20 ± 2°C, Note 1) and, when determined, the average content measured shall not differ from that de-clared by more than the following tolerance:

Note. the upper limit is included in the range

3 Physical properties

3.1 Emulsion stability and re-emulsification (MT 36.3, CIPAC Handbook K, p.137, 2003)

The formulation, when diluted at 30 ± 2ºC with CIPAC Standard Waters A and D, shall comply with the following:

Note: In applying MT 36.3, tests after 24 h are required only where results at 2 h are in doubt.

3.2 Persistent foam (MT 47.2, CIPAC Handbook F, p. 152, 1995) (Note 2)

Maximum: 10 ml after 1 min.

4 Storage Stability

4.1 Stability at 0°C (MT 39.3, CIPAC Handbook J, p. 126, 2000)

After storage at 0 ± 2°C for 7 days, the volume of solid and/or liquid which separates shall not be more than 0.3 ml.

4.2 Stability at elevated temperature (MT 46.3, CIPAC Handbook J, p. 128, 2000)

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 3) and the formulation shall continue to comply with the clause for:

- emulsion stability and re-emulsification (3.1)
