10% spud boost claim

POTATOES could get a 10% yield boost from Cutonic Bac-Up, a new foliar applied mix of calcium and boron, says manufacturer Lambson Fine Chemicals.

Across five independent UK trials yield increase averaged 4.38t/ha (1.8t/acre) from a tuber bulking/skin set timed application. Dutch work has shown a 0.6% rise in tuber dry matter.

The boron appears to act as a carrier for the calcium, helping translocation from the leaf to the tuber, says technical director Alan Hughes. &#42
