Do you know that....
- HARDI TWIN is minimising the loss on the ground and increasing the on-target deposit?
When moving the spray cloud down into the crop with huge amounts of air you could fear that most of it would end up at the ground - this is however not the case.
In the test below plants where cut into pieces after spraying and the amount of depositet chemicals where detected and compared with conventional spraying.

As an example +43% on the top leaf means that the plant sprayed with the TWIN has got 43% more deposit than the conventionally sprayed plants. The result from these tests shows that angling either forward or backwards reduces the loss on ground with 40 - 70%. This is due to the higher "filtering effect" from the crop when the spray hits at an angle - compared with the fact that the TWIN air moves the plants in the spray swath so they are able to catch more of the spray.
