Mixing and Spraying
Apply as a MEDIUM spray, as defined by BCPC.
For water volumes, see Section 3, above.
Remove the top filter. Fill the spray tank to the required volume with clean water and start the agitation. Then slowly add the required amount of Kumulus DF. Replace the filter, leave to disperse and continue agitation until spraying is completed.
When tank mixes are to be used, each product should be pre-diluted with water and added separately to the spray tank.
Kumulus DF may be applied from the air to wheat, barley and oilseed rape at the recommended rate in 25-60 litres of water per hectare. Aerial applications should not be made in tank mix with any other products.
