    did you read on the label about how to tell if it's okay to tank mix?
    from what i saw, sevin is compatible with many things.
    although i couldn't find it on a sevin label (please note that this sentence is in direct contradiction of the first sentence), the way compatibility between tank mixed chemicals is sometimes tested is:

    When tank mixing this product with other pesticides, observe all precautions
    and limitations on each separate label. The physical compatibility
    of this product may vary with different sources of pesticide products,
    and local cultural practices. Any tank mixture which has not been
    previously tested should be prepared on a small scale.

    Using a jar that is able to contain a minimum of a quart, add the proportionate
    amounts of the products to 1 qt. of water. Add wettable powders
    and water-dispersible granular products first, then liquid flowables,
    and emulsifiable concentrates last. After thoroughly mixing, let stand for
    at least 5 minutes. If the combination remains mixed or can be remixed
    readily, it is physically compatible.
    Once compatibility has been proven,
    use the same procedure for adding required ingredients to the spray
