Chateau label expanded for hops

The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Chateau herbicide for management of labeled weeds and sucker control on hops in Canada. Chateau herbicide was already labeled for use on a number of crops in Canada for control of several weeds. 

 

This minor use project was submitted by Ontario as a result of minor use priorities established by growers and extension personnel. 

 

The following is provided as an abbreviated, general outline only. Users should be making weed management decisions within a robust integrated weed management program and should consult the complete label before using Chateau herbicide.

Rate (g/ha)

Application Information

Hops

Sucker control or Labeled weeds

280-420

TIMING TO HOPS FOR SUCKER CONTROL

 

Apply Chateau herbicide WDG as a directed application after hops have reached a minimum of 1.8m (6 ft.) in height for sucker control. Application should be dire

 

TIMING TO HOPS FOR PREEMERGENCE WEED CONTROL

 

Apply Chateau herbicide WDG as a 30-45 cm (1 - 1.5 ft.) band to each side of the hop row. Apply to dormant hops in the fall to ensure time for rain incorporation and activation. If weeds are emerged at the time of application, tank mix Chateau herbicide WDG with a labeled burndown herbicide, such as carfentrazone-ethyl, to assist with control of emerged weeds.

 

 · Do not apply more than 420 g/ha in a single application. Do not apply more than 420 g/ha per season.

 

 · Do not allow spray to contact green stem (unless used for sucker control), foliage, flowers or cones, or unacceptable injury may occur.

Chateau herbicide is toxic to aquatic organisms, small wild animals, certain beneficial insects and non-target terrestrial plants. Do not apply this product or allow drift to other crops or non-target areas. Do not contaminate off-target areas or aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers. 

 

There are significant precautions and detailed directions for use on the Chateau herbicide label; follow these carefully.
