Herbicide Drift in vineyards

'Hormone' leaf.

Herbicide spray drift has been noted Langhorne Creek Wine Region and the Southern Fleurieu. For the vineyard pictured here the product Metsulphuron (tradenames Ally, Aim, Brush-offtm) is alleged to have drifted into a vineyard from a neighbouring property four weeks ago. Three weeks ago symptoms were seen. Herbicide drift shows as the ‘hormone’ shape, cupping and stunting of leaves (above and below) poor flowering and damage to the vine growing tips.

Disappointingly, herbicide spray drift is an ongoing issue in the area, and this is a timely reminder. 

Poor  shoot growth.
