Vegetable Seed Crops

In some seed-producing regions, contracting seed companies or seed associations have secured SLN (SLN) labels for members. These labels may not be listed here because the authors of this handbook wish to honor the third-party ownership of these labels and their restricted use. SLNs for Syngenta products are only found on this website (, therefore we have included specific directions in the text of each section on how to access these labels, or we have at least referenced other sections where that information is available.

We do not include Section 18 labels because of their transient nature.

If an herbicide is labeled for use in a given crop, that herbicide also may be used in producing seed for that vegetable, unless expressly forbidden on the label. Be sure to check vegetable crop sections of this handbook for additional herbicide listings. Uses listed here are specifically for seed crops, and are not labeled for use in crops grown for food.
