New herbicide approved for control of broadleaf and grass weeds in potato crops in New Zealand

A new herbicide that controls potato weeds, like black nightshade, has been approved by the Environmental Protection Authority for use in New Zealand, subject to certain conditions.

Boxer Gold contains the active ingredient prosulfocarb, which is new to New Zealand, but already approved in the European Union, Australia, and Japan. It also contains S-metolachlor. This ingredient is currently approved in New Zealand and is approved in other jurisdictions including the USA, Canada, Europe and Australia.

Boxer Gold is intended to be used as a herbicide for the treatment of broadleaf and grass weeds in potato crops. Benefits identified in the application process for this product include reduced resistance in weeds, leading to bigger potato crops, and more product choice for farmers.

A number of controls, or rules, have been set around the use of this product. These include that it can only be applied only once a year, and only on non-windy days. A buffer zone of five metres must be maintained to protect against spray drift into waterways.

This herbicide can only be applied by professional users, via methods such as tractor-driven boom spray.

Boxer Gold was approved following the EPA’s first ever fully online hearing for a new hazardous substance.
