Extension of Authorisation for Minor Use 0253/2013 ‘Wing-P’ (212.5 g/l dimethenamid-P and 250 g/l pendimethalin) on outdoor ornamental bulbs and outdoor ornamental plant production prior to emergence of the crop

This new Extension of Authorisation for Minor Use (EAMU) relates to the use of ‘Wing-P’ (M15425) as a herbicide for the control of annual weeds in outdoor ornamental bulbs and outdoor ornamental plant production prior to emergence of the crop, click on the ‘Download’ button to see the authorisation notice.

Neither the efficacy nor the phytotoxicity of the product for which this EAMU has been granted has been assessed and, as such, the user bears the risk in respect of failures concerning its efficacy or phytotoxicity.

IMPORTANT Additional information for Growers:

‘Wing P’ has not been tested on all ornamental crops or bulb crops, and growers are therefore strongly advised to test a small area of crop prior to wider commercial use. However use on narcissus (cv Tamsyn) was evaluated post-flower cropping in HDC project BOF 73. Growers are advised to refer to this report and to check tolerance of bulb varieties and other ornamentals before treating the whole crop.

Use on ornamental bulbs for cropping is restricted to pre-crop emergence use or post cropping (after harvesting of the flowers) and where transplantation of bulbs will not occur (i.e. post planting pre emergence use). For bulbs which are not to be flower cropped, application can be made at any growth stage before senescence of foliage. Use on outdoor ornamental plant production must be pre-crop emergence.
IMPORTANT: When applying this product under the terms of this Extension of Authorisation, comply with any resistance guidance or restrictions stated on the product label.

Total reliance on one pesticide will hasten the development of resistance. Pesticides of different chemical types or alternative control measures should be included in the planned programme. Alternating with different modes of action is a recognised anti-resistance strategy. Strains of some annual grasses (e.g. black-grass, wild oats and Italian rye-grass) have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop advisor or product manufacturer.

Extension of Authorisation for Minor Uses (EAMUs) are granted only in relation to a particular product for specific uses. It is an offence to use an approved product in a manner that does not comply with the specific conditions of approval that is laid down in the statutory Appendix 1 “Conditions of Extension of Authorisation” of the EAMU. To demonstrate compliance with such terms, a user must have read and understood the document before commencing spraying operations. Possession of a current EAMU document is generally taken as part of the “burden of proof” of this requirement. Only the original EAMU document, held by the Chemicals Regulation Directorate (“CRD”), constitutes a valid legal document.

No reliance should be placed on a EAMU by a user in relation to products which, although similar to an approved product, are not expressly covered by the EAMU.
