Application Information
With
:
Apply with ground equipment only. Do not apply by air.
Water volume
:
Ground application: 22 - 91 L/acre maximum.
Mixing Instructions
Use mixing instructions “c” on page 13.
Application Tips
The use of 80° stainless steel flat fan nozzles tilted 45° forward is recommended for optimum spray coverage. Use
high water volumes on dense crop canopies for better penetration to weeds. Best results will occur if applications
are made to weeds not stressed by lack of moisture, excessive moisture, low temperature and/or very low relative
humidity. Select/Centurion/Arrow/Shadow at 51 mL/acre should only be applied under the following conditions:
good crop stand, early application (prior to tillering), light to moderate weed infestation, adequate moisture and
fertility, absence of stress, good growing conditions.
How it Works
Select/Centurion/Arrow/Shadow are systemic herbicides that are translocated from the treated foliage to the growing
points of leaves, shoots and roots.
Expected Results
Weeds
:
Leaf foliage will first change from green to yellowish, then purplish and finally a brown colour.
The time required for complete control is 7 - 21 days following treatment, depending on growing conditions and crop
competition.
Restrictions
Rainfall
:
Rainfall within one hour of application may reduce the effectiveness of the spray.
Grazing
:
Do not cut treated crops for feed or graze until 60 days after application of clethodim to annual crops and
30
days after application to seedling alfalfa.
Pre-harvest Intervals
:
Canola, coriander, common dry beans, chickpeas (desi, Kabuli), flax (including Solin),
lentils, potatoes, and mustard (brown, yellow oriental): 60 days. Alfalfa and fenugreek: 30 days. Sunflower: 72 days.
Field peas: 75 days.
Environmental Precautions
Clethodim is moderately to highly toxic to aquatic organisms. Avoid contamination of aquatic systems during
application. Do not contaminate these systems through direct application, disposal of waste or cleaning of equipment.
Toxicity
Low oral toxicity. Acute oral LD
50
(
male rats) = 2,920 mg/kg.
Storage
Does not require heated storage.
