Aq. suspension concentrates comprise 5-50 w/v% pendimethalin (I) (dinitroaniline) 0-50 w/v% of one or more secondary pesticides 3-30 w/v% additives and 20-92 w/v% water. (I) has a ratio of orange crystal form to yellow crystal form of 4:96 to 100:0. The compsns. pref. comprise 20-40% (I), 0-50% of one or more pesticides which are water-sol. or have a m.pt. above 70 deg.C, 2-20% of a surfactant selected from opt. sulphonated cresol-or naphthalene-formaldehyde condensates and lignosulphonates, 0.05-2.5% of a suspending agent selected from xanthan gum, guar gum, gum arabic and cellulose derivs., 2-15% of an antifreeze selected from ethylene glycol, propylene glycol, and urea, 0.05-1% of a silicone antifoam, 0.05-2% of a thickener selected from clays, pptd. silicas, polyvinyl alcohols, PVP and polyacrylamide, 0.05-2.5% of a preservative (esp.
