HC Deb 10 March 2000 vol 345 c868W
Joan Ruddock

To ask the Minister of Agriculture, Fisheries and Food what are(a) the growing season for genetically modified herbicide tolerant winter oil seed rape in UK field trials and (b) the prohibited period for the use of the herbicide glufosinate ammonia in the UK; and on what research evidence the prohibited period for glufosinate ammonia is based. [111353]

Ms Quin

[holding answer 28 February 2000]: Genetically modified herbicide tolerant winter oil seed rape is sown at the end of August and the beginning of September; the crop is harvested in the following July or early August.

Approvals for the commercial use of glufosinate ammonium on oil seed rape all prohibit its use for weed control from 30 September to 1 March. This is because data submitted do not support its use on oil seed rape during that period.

However, experimental approvals have not imposed this prohibition.
