Crops, Diseases Controlled, Rates and Timing
Crops
Diseases
suppressed/
controlled
Rate per acre Timing and specific comments
Preplant
In soils where canola,
sunflower, dry edible
bean or lentil will be
planted (fields have a
history of white mould)
All susceptible crops
Sclerotinia
sclerotiorum
0.8
kg
Apply to soil prior to planting spring crop;
at least 3 months before the typical onset
of sclerotinia stem rot. Product must be
incorporated in the top 5 cm of the soil. The
product should be incorporated within 1
week of application.
All non-susceptible
crops (eg. cereal
crops)
0.4
kg
Apply to soil prior to planting a non-
susceptible crop. Incorporate product within
1
week of application. Product should be
incorporated in the top 5 cm of the soil.
Post-harvest
On harvest residues
(
fields have a history of
white mould)
Susceptible crop to
be grown next spring
Sclerotinia
sclerotiorum
0.6 - 0.8
kg
Apply product to crop residues after
harvest. Incorporation should occur within1
week of application. Product should be
incorporated in the top 5 cm of the soil.
Non-susceptible crop
next spring
0.4
kg
Maintenance
All crops (annual maintenance treatment after
initial application)
0.2 - 0.8
kg
After initial application of Contans, it is
recommended to apply a maintenance
treatment of 0.2 kg/ac to reduce inoculum
levels in the field. Annual maintenance
rate will depend on crop type and tillage
practices.
Application Information
How to Apply
:
Ground application only. Do not apply by air.
Water Volume
: 40
L/acre minimum.
Application Tips
Use sufficient water volume to ensure thorough coverage of the soil surface and/or crop residues. After incorporation,
treated soils should not be disturbed (e.g. plowed) to avoid bringing untreated sclerotia from lower soil depths to the
top soil layer. As part of an overall long term pest management strategy, it is recommended to use other management
practices in addition to Contans such as in-crop foliar applications and following proper crop rotations.
Do not tank mix with fungicides or fertilizers. Do not tank mix with acids, alkalis or any product that attacks organic
materials. Contact UAP Canada for more information on products that are compatable with Contans.
How it Works
When applied correctly, the active ingredient in Contans WG will destroy sclerotia in the soil before the sclerotia are
able to produce fruiting bodies. Regular use of Contans in successive years within a long term management strategy
will improve disease control.
Restrictions
Pre-harvest Interval
:
Contans WG can be applied up to and including the day of harvest.
Environmental Precautions
