Offering herb producers a herbicide option, Croptex Bronze (pentanochlor) is now approved for use this season.

The full label approval from the Pesticides Safety Directorate for celery and parsley also allows, under the Long Term Arrangements for Extension of Use, application to all herbs.

This extension of crop use has been gained with support from the HDC and the British Herb Trade Association.

An established herbicide for carrot and parsnip crops the extension of this label, offers a lifeline to growers of these specialised minor crops.

'Growers are suffering limited support from the large agrochemical manufacturers and are therefore running out of crop protection options,' said Peter Hingley, general manager of Certis.

'Pentanochlor is one of only 14 unsupported active substances that will be continued under the 'essential use' status that is applicable until 2007.

The long term arrangements use for other herbs is also extended for this period,' he added.

It offers mainly contact with some residual activity against a broad spectrum of weeds, including chickweed, knotgrass and fumitory. For the best results, Croptex Bronze should be applied early in the season, post-emergence of the crop and whilst the weeds are still small.
