Tordon 22K [picloram-potassium], Polidim [2,3,6-TBA-dimethylamine], simazine and their mixtures were incorporated 27-30 cm deep into the soil with chisel ploughing in autumn in the 1st yr of a maize/maize/winter wheat rotation. Tordon 22K at 1 kg a.i. alone and in mixtures with Polidim or simazine at 0.5 + 10 and 0.5 + 3 kg a.i./ha decreased the populations of C. repens and other weeds by 96% and increased the fodder/grain yields by 38-92%.
