A 'pregnancy-style' test which can be used on the farm to quickly detect the presence of herbicide resistance in black-grass is being launched today by Mologic Ltd, a developer of personalised diagnostics, and Newcastle University.

Sensitive enough to detect resistance in the early stages of blackgrass growth and giving a result in under five minutes, the new Black-grass REsistance Diagnostic tool – BReD – allows farmers to map non-target site herbicide resistance in populations of black-grass across the farm, giving rapid feedback on the effectiveness of weed control measures.

BReD - Works - Glutathione - Transferase - AmGSTF1—a

BReD works by detecting the glutathione transferase AmGSTF1—a protein that is found in high concentrations in black-grass populations that have evolved resistance to multiple classes of herbicide.

When the protein is present, an intense red band appears in a small window on the hand-held device within five minutes.

Years - Research - Chemical - Control - Weed

Founded on 20 years of research into the chemical control of this weed led by Professor Rob Edwards at Newcastle University, BReD has been developed as a new tool in the armoury to slow the spread of the UK's most devastating weed.

Research lead Professor Rob Edwards, Professor of Agriculture at Newcastle University, explains:

Tests - Place - Medicine - Pregnancy - Diabetes

"Early-indication diagnostic tests are common place in medicine, such as for pregnancy or diabetes, and are used to help people make decisions much earlier on with the aim of improving the long term outcome. It should be no different in agriculture."

"This new diagnostic tool marks an important step in our fight against resistance, using the latest research to deliver solutions in crop protection."

Approach - Agriculture - BReD - Series - Diagnostics

"It is an approach we have termed 'personalised agriculture', and BReD represents the first in a series of diagnostics we are working on to counteract resistance and emerging disease in the agricultural setting."

Mitch Brooker, General Manager at Mologic adds:

"Mologic has a proud history in forming lasting partnerships with both academic and commercial organisations....
