Plant growth regulators
Plant growth regulators function as plant hormones to manipulate the growth and development of plant cells. Their use in agriculture is regulated by the Australian Pesticides and Veterinary Medicines Authority. Five plant growth regulators are currently registered for use in viticulture and these are listed on page 21 of the ‘Dog Book’.
For grapes destined for export wine, the use of chlormequat or ethephon is not recommended. The AWRI advises that you contact your winery/grape purchaser prior to the application of any plant growth regulator.
