Always check the source of cover crop seed and make sure a lab has analyzed the seed lots for weed seed before planting them.
“Cover crops are typically smaller seeded, which could harbor unwanted weed seeds,” says Brenda Sievers, plant industry program manager for the South Dakota Department of Agriculture. “Knowing your seed source and what you are planting will reduce unwanted weed pressure and prevent future problems with germination or other issues that might show up in your field.”
The label must include percentages for germination, purity, other crop, and inert matter as well as restricted noxious weed seeds.
Seed cannot contain prohibited noxious weed seeds in any amount. Prohibited noxious weed seeds in South Dakota include field bindweed, leafy spurge, hoary cress, Russian knapweed, perennial sow thistle, Canada thistle, Palmer amaranth and horse nettle.
The labeler’s name and address must also be listed on the label.Source: SDDA, which is solely responsible for the information provided and is wholly owned by the source. Informa Business Media and all its subsidiaries are not responsible for any of the content contained in this information asset.
