[QUOTE="Hindsight, post: 6877364, member: 3169"] I concur with previous posters. As way of background for future reference a weakness of Pendimethalin is matricaria species - so mayweeds and groundsel. In years gone by I used to add a small dose of Lexus (flupysulfuron) to the autumn Flufanacet + DFF + Pendimethalin mix. Spring control of Groundsel relies mainly on SU or Forasulam, both are ALS inhibitors. Metsulfuron (Ally) is weaker on groundsel. Groundsel best to have some Tribenuron in the mix or Florasulam. To encourage debate there is possibility of clopyralid - but limited weed spectrum. Speedwells at this time - Harmony M (metsulfuron = thifensulfuron) or Arylex. If use Arylex its weakness is matricaria species. Speedwells - Ivy leaf or Common Field speedwell? Speedwells tend to be a low growing early senescencing weed. If at low levels do they need to be totally controlled? Only you will know of course Pixxaro - you may need some SU / Florasulam to beef up activity on groundsel. Plenty there to discuss with an agronomist. [/QUOTE]
