Potato Review

MACHINERY FOCUS: HAULM PULLING I N the post diquat world, many potato growers are already using, or considering, haulm destruction methods for their crop, considering the costs and efficacy implications. Many growers now use haulm topping as their preferred method to remove the bulk of the haulm followed with an application of a PPO inhibitor such as Spotlight Plus (Carfentrazone) and Gozai (Pyraflufen- ethyl) to stop passive bulking and to control tuber size, and achieve skin set. This has proven to be an effective method but its effectiveness relies on sometimes repeated applications of these expensive actives to achieve the desired results. However in aworldwhere the E.L.M. scheme looms large on the horizon, with its focus on sustainability and the probable further reduction in reliance on chemical inputs across the sector, there is a need to find anotherway. The organic sectorwould also benefit fromthis simple and effective approach. Haulm pulling is a potential alternative to chemical application. Previously haulm Precision haulm pulling We highlight recent trials by a Dutch company that have sought to refine the mechanical pulling process to provide a new alternative to PPO inhibitor application in the UK. pulling has seen crop losses as a result of damage and greening which occurs when the stolon and tuber separation is not complete. Dutch brand, Vegniek, has been working to refine the mechanical pulling process and with its DiscMaster series of precision haulm pullers, which it has just launched into the UK for the first time. Its focus has been on reducing crop damage www. tongengineering .com e: sales@tongengineering.com t: +44 (0)1790 752771 > Gentle Handling > Advanced Design > Intelligent Control INNOVATIVE DESIGN FROM FARM TO PACK TURNKEY PROCESSING SOLUTIONS OPTICAL SORTING IN-FIELD & ON-FARM UNRIVALLEDCLEANING&GRADING ADVANCED BOX HANDLING WASHING & POLISHING THE COMPLETE SOLUTION Designed with you in mind
