Why does a product I previously used no longer show up when I search it to use in a CropIQ application?

Question:

Why does a product I previously used no longer show up when I search it to use in a Crop IQ application? (i.e. the product becomes "inactive" or "expired")

Answer:

Products may be removed from the market over time by the manufacturer or registrant.  This is particularly true of EPA registered products.  If a product is no longer registered for use with EPA or in a given state, that product will not be available for selection in Crop IQ.
