Special Requirements for Crops Grown for Seed

If you grow a seed crop, apply pesticides to seed crops or are a seed conditioner, take time to learn your responsibilities associated with the use of pesticides registered through the Special Local Need (SLN) process.

Most SLN labels that are for the use of a specific pesticide on a seed crop do not have a food or feed tolerance. Applicators, growers, and seed conditioners must comply with the use restrictions on the pesticide label. These specialty seed crop registrations are only made possible with these restrictions to prevent ANY pesticide residues from entering food/feed channels of trade.

The following summary of responsibilities are clearly spelled out on each pesticide label:
  • Crop is declared a non-feed/non-food use.
  • No portion of seed crop may be used or distributed for food or feed, including (not limited to) green chop, forage, hay, pellets, meal, whole seed, cracked seed, straw, roots, bulbs, foliage or seed screenings.
  • No grazing of the crop, stubble, or regrowth.
  • Seed screenings must be disposed of (not used for feed).
  • Specific records of pesticide applications, distribution and disposal of crop or crop parts is required.
  • Seed from a treated field MUST bear specific and conspicuous container labeling stating:
“This seed was produced using one or more products for which the United States Environmental Protection Agency has not established pesticide residue tolerances. This seed, in whole, as sprouts, or in any form, may not be used for human consumption or animal feed. Failure to comply with this condition may violate the requirements of the Federal Food and Drug Administration, the Oregon Department of Agriculture and other regulatory agencies.”

These restrictions apply to SLN registrations for the following seed crops:
Alfalfa, alliums (except garlic), arugula, beet(garden and sugar), birdsfoot trefoil, broccoli, brussels sprouts, burdock, cabbage (including chinese), carrot, cauliflower, celery, cilantro/corriander, clover, collards, cucumber. dill, drug and medicinal crops, endive, escarole, herbs (culinary), herbs (dietary supplement), kale (including chinese), kohlrabi, lettuce, meadowfoam, mizuna, mustard (including chinese), parsley, parsnip, radish (except daikon), rapeseed (industrial oil only), rutabaga, spinach, squash (summer), squash (winter except pumpkin), Swiss chard, turnip, and vetch.

Not complying with these directions will jeopardize the registration status of these products and specialty seed crop uses. Growers, applicators, and conditioners must communicate as they share responsibility to keep illegal residues out of the food/feed chain. To view most SLN labels refer to:
