Four potato toppers compared: The proof of the pudding is in the spec

Unable to use Reglone, the popular desiccant containing diquat, potato growers are now having to find other ways to remove the crop's haulm. One obvious mechanical option is a topper, so we put four of them to the test ... to find out how they perform

Potato growers are facing a massive challenge when it comes to dealing with crop haulm. There's certainly no shortage of chemical solutions, but there is a huge gap between the costs and the benefits. Other options are using gas to burn it or high-voltage electric, but both of these methods are not as straightforward or costeffective as topping, particularly when there is a quick change of plan.
