PGR advice lifts yields

SPRING barley averages an 8% yield response to safened-chlormequat product Adjust, says Dalgety pgr specialist Colin Lloyd.

Applied at GS12-13, the three-leaf stage of the plant, it suppresses apical dominance to increase tiller numbers.

The safened formulation means it will work in cold conditions, even between frosts, he maintains. Tillers are a more even size in treated crops which results in less screenings, he adds.

A full-rate application of 1.25 litres/ha costs about £10/ha. Adjust and Mandops product Barleyquat are the only chlormequats approved for use on spring barley at this stage, he says. &#42
