Tordon 22-K picloram-potassium 24.9% was applied at 0.0036-0.0327 mg/kg to a 2:2:1 mixture of peat + soil + sand, in which French beans were sown as bioassay plants, in the glasshouse. The surface area of whole leaves was taken as a quantitative assessment of picloram residues in the soil. The sensitivity of the method was 0.003-0.004 mg/kg. Residues in the soil of 0.1 mg/kg reduced grain yields of wheat by 20% while 0.2 mg/kg almost entirely prevented grain formation.
