In its current edition, the Australian Potato-Link magazine reports on crop.zone’s technology and the outstanding test results.
Trials in 2020 compared the effectiveness of CROP.ZONE against two herbicides still registered for haulm kill in Europe.
The most effective treatment was two passes with CROP.ZONE in opposing directions. This killed >65% of stems, with the remainder yellowed (after three weeks). Although two passes in the same direction increased the number of dead stems to over 80%, around 10% green stems remained, particularly between the hills.
In contrast, the two herbicides left approximately 20% yellow and 20% green stems. This low efficacy level was surprising. Although both herbicides require sunlight to be effective, conditions in 2020 were ideal. As a result, three herbicide treatments were needed to achieve.
