Introduction

71
when field bindweed is in the flowering stage and allow 3 weeks after treatment before resuming normal summerfallow
tillage.
Basagran - In labelled crops, apply 0.71 L/acre followed by 0.71 L/acre 7 to 10 days later. Apply in 20 to 35 gallons/ acre
(90 to 160 L/acre) water before field bindweed has developed a dark green colour and before it has begun trailing. Use a
recommended surfactant (see recommendations under the appropriate crop).
2,4-DB - As a spot treatment in labelled crops apply 2.83 to 4.86 L/acre in 10 gallons/acre (45 L/acre) water at the bud
stage. Do not disturb plants for at least 10 days following treatment. Heavy rainfall within 2 hours of application may wash
chemical off the foliage and a repeat treatment may be required. Rainfall occurring within 6 hours after application may
reduce control.
2,4-D amine - In grass pastures containing no legumes or as a spot treatment, apply 1.82 L/acre of formulations containing
500 g/L 2,4-D amine at early flowering stage.
Glyphosate - As a spot treatment, apply 2.8 to 4.9 L/acre (360 g/L formulations or equivalent of other formulations) in
10 to 30 gallons/acre (45 to 135 L/acre) at the full bloom stage or beyond. Allow 7 or more days after application before
tillage.
Restore II - For season long control in grass pastures and rangeland only, apply Restore II at 0.97 L/acre.
Tordon 22K - In rangeland and grass pasture, apply 3.6 L/acre in 90 to 180 gallons/acre (400 to 800 L/acre) for spot
treatment, using hand wand application equipment only, to a maximum of one acre of every two acre area of land. of
water to actively growing weeds. WARNING - Picloram is a very persistent and water-soluble herbicide. Do not apply to
permeable soil. Do not apply to irrigated areas. Take special precautions to prevent drift.
Weed Control
Field Horsetail
Amitrol 240 - Apply 5.0 to 6.7 L/acre in 10 to 30 gallons/ acre (45 to 135 L/acre) water in non-cropped areas and pastures
when the weed is young and actively growing.
MCPA amine, potassium and sodium salt mixtures - Apply 0.57 L/acre of formulations containing 500 g/L MCPA after the
weeds have fully emerged for top growth control. May be used in wheat, oats, barley, flax and rye.
Foxtail Barley
Focus - Apply in fall or spring as a pre-plant or pre-emergent treatment to wheat, spring or winter, corn or soybeans for preemergent
suppression of downy brome and Japanese brome. For best results use in a program with glyphosate.
Glyphosate - Prior to crop emergence, apply 1 to 2 L/acre (360 g/L formulations or equivalent of other formulations) in
5 to 10 gallons/acre (23 to 45 L/acre) water to foxtail barley at the seedling to heading stage. Late fall applications may
provide better control of established plants than spring applications.
Glyphosate - In glyphosate tolerant canola, apply 2 applications, each at 0.5 L/acre (360 g/L formulations or equivalent of
other formulations), for season long control.
Glykamba - Prior to crop emergence, apply 1.26 L/acre in 5 to 10 gallonsIacre (23 to 45 LIacre) water to foxtail barley before
initiation of the seed head for suppression only.
Gramoxone - Apply 2.23 L/acre in 98 gallons/acre (445 L/acre) water or 75 mL in 2.2 gallons (10 L) water/1076 square feet
(100 sq. m) for top growth control only.
Kerb - Apply registered rates in 20 gallons/acre (90 L/acre) water between October 1 and freeze-up. Use the lower rate on
grey-wooded soils or where perennial bluegrass or fescues are the predominant pasture species. Do not use Kerb for foxtail
barley removal in seed grass stands or desired foliage stands of timothy or fescue grass species. At recommended rates,
pasture stands of perennial bluegrass and fescue may be reduced by 10 to 15 percent. Where perennial bluegrass and
fescues are the dominant pasture species, use the lower rate of Kerb. Spray overlaps may seriously harm desirable pasture
grass species. Where the grass stand comprises mostly foxtail barley and reseeding to a desirable grass species is required,
delay seeding into the Kerb-treated soil until the end of June. Do not harvest or graze within 60 days of application with
Kerb. Avoid using Kerb on soils having more than 6 percent organic matter.
Quizalofop - in registered crops apply 200 mL/ac to foxtail barley in the maximum 3-4 leaf + 3 tiller stage (control with
Assure II only and suppression with Yuma GL).
