POLAR* (GF-2463=Dow 24630 H) contains the active ingredients florasulam and clopyralid both well known substances found in commercial products such as Primus*3 (florasulam), Starane XL* (florasulam, fluroxypyr), Ariane C* (florasulam, fluroxypyr, clopyralid) or Lontrel* (clopyralid). POLAR* has a broad dicotyledonous weed spectrum and controls Galium aparine, Matricaria spp., Centaurea cyanus, Stellaria media, cruciferous weeds (Brassica spp. and others), Polygonum spp., Solanum nigrum and other weeds when applied post-emergence in spring. Increasingly important weeds in cereal production such as C. cyanus as well as G. aparine and Matricaria spp. at late growth stages can be controlled very efficiently at BBCH 13 to 32 in winter cereals and at BBCH 13 to 30 in spring cereals. POLAR* is formulated as a Suspension Concentrate (SC) with a target dose rate of 200 ml/ha (60 g ai/ha clopyralid + 5 g ai/ha florasulam) in winter and spring cereals. It combines two modes of action: Auxin-like (clopyralid) and acetolactate synthase (ALS) inhibitors (florasulam) and can be safely applied in spring (soft and hard) and winter wheat, spring and winter barley, spring oats, winter rye, winter triticale and spelt.
