Application Tips
Do not use more than 7 gm/acre/year. Do not apply to crops underseeded to legumes or grasses. With any
summerfallow treatment, allow at least 10 days to elapse between treatment and tillage. Only weeds emerged at time
of application will be controlled. Weeds must be actively growing at time of application or control might be reduced.
Do not re-enter treated fields until 12 hours after application. Once dissolved, Express® Pro herbicide will not settle
out, even if the sprayer is parked for long periods of time. Spray preparation should be used within 24 hours or
product degradation may occur.
Do not use on highly variable soils that have large gravelly or sandy areas, eroded knolls or calcium deposits.
•
Express Pro applied to fields to be planted to spring wheat, durum wheat, winter wheat or barley that are stressed
by severe conditions such as drought, low fertility, saline soils, waterlogged soils (soils at or near field capacity),
disease or insect damage may result in crop injury as crop injury may occur. Heavy rainfall soon after application
may result in visual crop injury or possible yield reduction. Conditions such as thin crop stand, sandy soil or low
soil organic matter may increase the severity of injury.
How it Works
Express Pro rapidly stops growth of susceptible weeds. However, typical symptoms (discolouration) of dying weeds
may not be noticeable for 1 to 3 weeks after application, depending on growing conditions and weed susceptibility.
Degree of control and duration of effect depend on weed sensitivity, weed size, spray coverage and growing
conditions. Activity of the herbicide mixture may be delayed by cold, dry conditions after application.
Rainfall
:
Heavy rainfall immediately after application may wash the herbicide off the foliage, which may reduce the
effectiveness of Express Pro. Do not apply if rain is forecast for the time of application.
