Bupirimate (systematic name 5-butyl-2-ethylamino-6-methylpyrimidin-4-yldimethylsulphamate; brand names Nimrod and Roseclear 2) is an active ingredient of plant protection products (or pesticides), which has an effect as a fungicide.[1] It belongs to the chemical family of pyrimidines. Bupirimate has translaminar mobility and systemic translocation in the xylem. It acts mainly by inhibiting sporulation and is used for control of powdery mildew of apples, pears, stone fruit, cucurbits, roses and other ornamentals, strawberries, gooseberries, currants, raspberries, hops, beets and other crops. Bupirimate is not an insecticide. It is of low mammalian toxicity and is non-toxic to bees. However, it is used in many products which also contain insecticides.
