Wiping out weed-beet case study
During 2001 a local farmer growing sugar beet discussed the problem of weed-beet in his sugar beet crop. He had been using weed wipers for
many years and accepted there was a fundamental problem in the design - they dripped chemical solution onto the desirable crop below.
The problem occurred when the weed population was relatively sparse. Consequently, the pump was replenishing product onto the wiping area
before the same amount of product had been used.
This resulted in an over saturation of the wiping area causing the unit to drip onto the sugar beet crop below.
The unit the farmer had been using was designed in such a way that it could not be modified to overcome the problem and so began the task
of finding or designing a unit that would not drip.
