Application Information:
Application Timing
400 to 800 g Prior to planting of spring crop; three months
before the typical onset of sclerotinia white
mould or stem rot.
In fall, prior to spring planting of susceptible
crop. After application to the soil, the product
should be incorporated to within 5 cm of the
topsoil.
Incorporation should take place as soon as
possible after application (within 1 week
maximum).
800 to 1600 g If soil incorporation is to a depth greater
than 5 cm, higher rate should be applied.
200 to 400 g Prior to the next soil treatment, the residues
of the susceptible crops in rotation can be
also treated to help reduce inoculum loads
of sclerotia in the field.
• Use sufficient water volumes to give thorough coverage of the soil surface and/or the crop residue (10 gallons per acre
of water volume).
• DO NOT allow spray mixture to stand overnight or for prolonged periods; should be used within 24 hours of being
prepared.
• After incorporation, treated soils should not be disturbed 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
along with Contans WG such as in season foliar fungicide applications and proper crop rotations.
• DO NOT apply by air.
