I'm also not sure why you think they were ineffective. In 2003, these inspection stations confiscated 16,000 some lots of prohibited or pest-infested plants/fruits from private vehicles.
Every time but one that I've driven through the checkpoint, the staff waved me through without even stopping. The one time the car was stopped, they asked if we had any fruits or vegetables, we said no, and they waved us on.
That doesn't seem especially effective. Clearly, the system could be fixed by making everyone remove their shoes as part of the check.
