An independent claim is included for preparation of compound (I). [Image] - ACTIVITY : Herbicide; Plant growth regulant. The pre-emergence herbicidal efficacy of 4-amino-2-[(1R)-1,2,3,4-tetrahydronaphthalen-1-ylamino]py rimidine-5-carbonitrile (Ia) against Alopecurus myosuroides was tested as follows: compound (Ia) was applied at the rate of 320 l/hectare and percentage control of weed was measured. The compound (Ia) showed 100% control of weed. - MECHANISM OF ACTION : None given. |
