Introduction

181
Use the high registered rate for each crop to control the following weeds:
º Canada thistle (top
growth only)***
º Cleavers
(1 to 2 whorls)**
º Cow cockle
º Field bindweed †
º Velvetleaf
º Flixweed*
º Jerusalem artichoke
º Round-leaved
mallow**
º Shepherd’s-purse*
º Tartary buckwheat
†
Apply when actively flowering.
* Rosette stage in winter wheat.
** Suppression only.
*** Canada thistle should be treated when 6 to 8 inches (15 to 20 cm) of new growth is present after harvest and in
the early bud stage in fallow.
Rates for Native Range and Pasture will control:
º Alder
º Bull thistle
º Chicory
º Goat’s-beard
º Poison ivy
º Ragwort
º Sheep laurel
º White cockle
The high rate for each crop should be used for all weeds under adverse growing conditions, when weeds are at an
advanced stage of growth or when weed densities are high. Guidelines are not provided for weed densities under light or
heavy infestations. When in doubt as to the infestation level, use the high rate or contact the manufacturer.
Weed Control
NOTE: It is possible that poisonous plants such as ragworts, hemlocks and death camas could be more palatable to livestock after
treatment with DyVel DSp. Suitable precautions should be taken to avoid livestock access when such plants are present.
Application Information:
• Water Volume:
º Cereals: Minimum 40 L per acre.
º Corn: 81 to 142 L per acre.
• Nozzles and Pressure: Maximum 30 to 40 psi (200 to 275 kPa) when using conventional flat fan nozzles. Low drift
nozzles may require higher pressures for proper performance. Use a combination of nozzles and pressure designed to
deliver thorough, even coverage with ASABE coarse classification or larger droplets.
How it Works:
Refer to Table 9 on page 48.
Effects of Growing Conditions:
Crops under stress from excess moisture, drought or disease may suffer a setback when this herbicide is applied. DO NOT
apply when temperature exceeds 27 o C or when relative humidity is high. Stubble treatments for thistle control in fall should
be made at least 2 weeks prior to killing frost.
DO NOT apply DyVel DSp at wind speed greater than 5 mph (8 km/hr).
Tank Mixes:
Herbicides:
• AAtrex Liquid (0.91 L per acre).
Insecticides: None registered.
Fungicides: None registered.
Fertilizers: None registered.
Note: The above mixes are those listed on the DyVel DSp label only.
Adding ingredients in the correct order is critical for optimum performance. Check labels of products to be mixed for
directions. General guidelines can be found on page 8.
