It is most commonly available as microgranules containing 15 % active ingredients ( AI ), or emulsifiable concentrate containing 480 g / litre of AI . Homologuation in Europe requires a maximum dose of 2, 400 g per hectare of AI, or 5 litres / hectare of emulsifiable concentrate or 17 kg / ha of microgranules.

The energy-depth-dose profile is a curve starting with a surface dose, ascending to the maximum dose in a certain depth d m ( usually normalized as 100 % dose ), then descends slowly through depths of 90 % dose ( d 90 ) and 80 % dose ( d 80 ), then falls off linearly and relatively sharply though depth of 50 % dose ( d 50 ).
